Principle and Structure of Copeland Scroll Compressor
The Copeland scroll compressor is mainly composed of a moving disk (vortex revolver), static disk (vortex stator), bracket, Oldham coupling ring, back pressure cavity, and eccentric shaft;
The principle of the Copeland unit scroll compressor is that the scroll line of the moving plate and the static plate are the same.
But there is a phase difference of 180° to mesh, thereby forming a series of enclosed spaces;
When the static plate is not moving, the moving plate revolves around the fixed plate with the eccentricity as the radius.
During the revolving process of the moving plate, it meshes successively to continuously compress the crescent-shaped area.
So as to achieve the purpose of continuously compressing the gas, and then it is discharged from the center of the static plate;
Why You Choose Copeland Condensing Unit?
Let’s see the advantages and disadvantages of Copeland scroll compressors and you will know why Copeland condensing unit is so popular all over the world.
What are the Advantages of Copeland Scroll Compressors?
√ The eccentric shaft that drives the moving plate can rotate at a high speed, and the Copeland unit scroll compressor is small in size and light in weight;
√ The force change of moving parts such as the moving plate and the main shaft is small.
So the whole machine runs relatively smoothly, and there is almost no vibration;
√ The Copeland unit scroll compressor has strong adaptability in variable speed movement and frequency conversion speed regulation technology;
√ The Copeland unit scroll compressor has very little noise when it is running;
√ The tightness of the Copeland scroll compressor is very good, and its refrigeration coefficient will increase slightly with the increase of operating time;
√ The Copeland scroll compressor works very well within the proper working conditions, especially in the heating working conditions of the heat pump air conditioning system;
√ The Copeland scroll compressor has no clearance volume, so it can maintain high volume efficiency operation;
√ The Copeland unit scroll compressor has few operating parts and no reciprocating operating structure.
So its reliability is very high, its life is very long and it is easy to realize automation;
What are the Disadvantages of Copeland Scroll Compressors?
√ The manufacturing cost of the Copeland condensing unit scroll compressor is relatively high because most of its running parts are curved surfaces.
And the processing and inspection of such curved surfaces are more complicated.
And the accuracy requirements for processing equipment and self-aligning assembly technology are relatively high.
√ In order to achieve a good seal, the Copeland scroll compressor must maintain a certain movement gap.
Because of this, its compression ratio is low, so the cooling capacity is relatively low.

What Should You Do Before You First Start the Copeland Condensing Unit?
For open-type compressors, check whether there are obstacles in the transmission running parts and whether the protection device is in good condition.
Check whether the berth is normal for the compressor equipped with oil sight glass.
For freon refrigeration compressors equipped with oil heaters.
They should be energized and heated before starting to make the freon dissolved in the oil volatilize and the oil pump can work normally.
The heating time is subject to the regulations in the product manual.
The pressure gauge valve should be opened and observe whether the pressure is normal.
If the oil system is equipped with an oil three-way valve, make sure that the handle of the oil three-way valve is in the working position.
The compressor with an energy regulating device or unloading device should be set at the minimum load or no-load position.
The shaft seal should be checked for the open type.
If there is a valve in the return pipe of the mechanical shaft seal, the valve should be opened, and the gland of the packing shaft seal should be loosened slightly.
Check whether the opening and closing conditions of the manual valves on the refrigeration system pipeline are correct.
Check whether the safety valves, pressure gauges, liquid level indicators, and other front shut-off valves and pressure-equalizing valves on each device are open.
However, the filling valve, oil collector, and air discharge valve should be closed.
Check whether the refrigerant liquid level in the liquid receiver and other equipment is within the required range.
Check whether there are obstacles in the running parts of the water pump and fan and whether the motor and various equipment are normal.
For water-cooled condensers, open the condenser inlet and outlet valves.
The horizontal shell and tube condenser closes the drain valve and opens the breather valve.
Start the water pump, connect the power to the condenser and compressor water jacket, and crankcase the oil cooler.
Turn on the power and prepare to start.
Copeland Condensing Unit Digital Scroll Compressor
The compressor in the refrigeration system is the core component of the entire refrigeration system.
And the performance of the compressor directly affects the effect of the refrigeration unit.
So we should discuss the compressor characteristics of the unit.
What is Copeland digital scroll compressor condensing unit?
How does a Copeland digital scrollwork?
Why does the Copeland AC condensing unit need a digital scroll compressor?
Everything you want to know about the Copeland scroll AC unit and Copeland scroll compressor is here.
Why is the Copeland Scroll AC Unit Compressor Called “Digital Scroll”?
The Copeland scroll ac unit compressor is alternately in two states, load state and unloads state.
In the load state, the compressor outputs at full capacity (1).
And in the unloaded state, the compressor has no output (0).
Because it changes between 1 and 0 in the set period, it is called a digital AC scroll.
How Much Energy Can the Copeland Digital Compressor Save?
For the modulation system, the Seasonal Energy Efficiency Ratio (SEER) is the standard measure of energy saving in operating the system throughout the year.
Compared with the seasonal energy efficiency ratio of the standard Copeland condensing unit scroll system, the Copeland condensing unit digital scroll system has increased by 20%.
Different system designs have slightly different actual energy savings figures, but conservatively speaking, the energy savings will exceed 20% compared to fixed-speed systems.
How Can the Copeland Digital Compressor Save Energy?
There are two factors for saving energy under partial load.
When operating under partial load, the Copeland scroll ac unit compressor runs for a period of time in an unloaded state.
The duration of the unloading state depends on the percentage of deflection.
The percentage of low deflection makes the unloading run longer.
In the unloaded state, the load on the scroll is very low (because there is no refrigerant suction), so little energy is consumed.
The test proves that the power consumption during unloading is only 10% of the full load power.
Low unloading power consumption saves energy in the part-load phase.
The second factor that contributes to operation under partial load is the wide operating range of the Copeland scroll ac unit compressor.
The capacity adjustment range of the Digital Scroll is 10-100%.
Therefore, even at a very low capacity (10%, 20%, 30%, etc.), the Copeland condensing unit compressor still does not require any hot gas bypass or on/off control.
The bypass will reduce the COP of the system, and because the Copeland condensing unit digital scroll does not require any bypass, it can save more energy.
Why is the Copeland Digital Compressor Easy to Return Oil?
Copeland scroll ac unit compressors do not use oil to seal the sides of the scroll.
So the basic oil circulation rate is very low compared to other manufacturers’ products.
Copeland scroll ac unit compressors are prone to return oil for two reasons;
One is that the oil only leaves the compressor under load.
In the unloaded state, because the refrigerant has no mass velocity, the oil does not leave the compressor.
Therefore, in the low load process, when the unloading time is long, only a small amount of oil leaves the compressor.
The second factor is that when the oil leaves the compressor under load, the gas velocity is sufficient to return the oil to the compressor.
What is the Variable Capacity Principle of the Copeland Digital Compressor?
The Copeland scroll ac unit operates in two states-load states and unloaded states.
The Copeland scroll ac compressor unit is equipped with an external solenoid valve.
When the solenoid valve receives a 220V signal, the top vortex moves up about 1 mm.
The movement of the top scroll creates a gap between the two scrolls, and there is no axial seal between the scrolls.
In this way, even if the motor is running, the compressor still cannot compress the refrigerant.
The capacity in the loaded state is 100%, and the capacity in the unloaded state is 0%.
The average output capacity of the compressor is the time average of the load state and the unloaded state.
For example: when the cycle time is 20 seconds if the Copeland condensing unit digital scroll is loaded and unloaded for 10 seconds each, the time average capacity is 50%.
What is the Starting Current of the Copeland Digital Compressor?
The starting current of the Copeland condensing unit digital scroll is the same as that of the standard scroll.
This is because the starting current is a function of the locked rotor current, which is the same for all scroll compressors.
In addition, the Copeland condensing unit Digital Scroll can be started in an unloaded state to ensure low current consumption.
Are There Electromagnetic Interference Problems?
The loading and unloading of the Copeland condensing unit digital scroll is a mechanical operation and does not generate any frequency that may affect other electronic equipment.
Therefore, the digital system does not require expensive electromagnetic suppression electronic devices, which also increases its reliability and simplicity.
How Long Time Does the Solenoid Valve and Compressor Use?
The external type solenoid valve that is used in the Copeland condensing unit Digital Scroll is a specially designed long-life valve and cannot be replaced by a standard solenoid valve.
The service life of this valve is 40 million cycles equivalent to 15 years of continuous operation.
All components in the Copeland condensing unit Digital Scroll can withstand long-term continuous load and unload operation.
What are the Advantages of the Copeland Digital Compressor?
There are many advantages to Copeland condensing unit digital scroll compressor:
A. The Copeland condensing unit digital scroll compressor system has the widest variable capacity range, reaching 10-100%.
The variable capacity range of the frequency converter system is often indicated by the frequency range of the compressor, which is generally 40-120 Hz.
After being transformed into the system, the variable capacity range is only 50-100%.
B. The Copeland condensing unit digital scroll compressor’s electronic device is very simple, so it is easier for the manufacturer to manufacture the Digital Scroll system.
C. The Copeland condensing unit digital scroll compressor has no electromagnetic interference problems.
D. Because the Copeland condensing unit Digital Scroll compressor has a wider range and stepless variable capacity output, the system has more precise room temperature control.
E. Because the overall system structure of the Copeland condensing unit Digital Scroll compressor is much simpler, the system’s reliability is improved.
F. The manufacturer only needs two digital control boards to develop a complete model series, one for a single compressor system and the other for a parallel/triple system.
What is the Current Change During the Loading and Unloading Stages?
In the loading and unloading state, the Copeland condensing unit digital scroll compressor rotates at a constant speed.
Since the motor is always running, no starting current is required to change from the unloaded state to the loaded state.
In the loading and unloading state, the current fluctuation is low and does not affect any other electrical equipment.
What Types of Copeland Digital Compressor Unit Refrigerants?
In the next few years, new models using R410A will be introduced.
The Copeland condensing unit digital scroll compressor is also used in refrigeration devices using R404A.
What About the Copeland Digital Compressor Unit Cycle Time?
Cycle time is an integral part of the Copeland condensing unit Digital Scroll compressor operation.
The cycle time includes 220 volt (V) and 0-volt signals sent to the external solenoid valve.
The 220V solenoid valve signal triggers the unloading state, and the 0V signal triggers the load state.
The cycle time between the load state and the unloaded state is the average capacity.
Copeland condensing unit recommends a maximum cycle time of 30 seconds.
When the cycle time exceeds 30 seconds, it will affect the cooling of the motor and the service life of the compressor.
Is There Any Obvious Noise Between Load and Unload?
There is a clear sound difference between the loaded and unloaded states.
As far as the average sound pressure is concerned, compared with the unloaded state, the sound pressure of the loaded state is 2 dbA higher.
The sound quality of the two states is different.
If the sound becomes a problem, installing a sound jacket on the compressor is very effective.
In addition, the compressor can be installed in a soundproof room.
What is the Average Energy Efficiency Ratio of the Digital Compressor?
The energy efficiency ratio largely depends on the system structure, and there is no single energy efficiency ratio for low-load operation.
To evaluate the compressor performance in your system, please contact a Miracle engineer.
Why Does the Compressor Have No Discharge Temperature Protection?
The fixed-speed compressor adopts an internal temperature protection-hot plate.
This is a bimetallic device that opens when the vortex temperature exceeds 143°C.
Due to space limitations in the Digital Scroll compressor, there is no internal hot plate.
Instead of a hot plate is an exhaust thermistor that measures the hot gas’s temperature.
Why Installed Check Valve on the Digital Scroll Compressor?
An exhaust valve is installed near the exhaust pipe of the standard Copeland condensing unit Scroll compressor and this valve helps to minimize downtime.
In the Copeland condensing unit Digital Scroll compressor, there is no such exhaust valve.
To avoid that any hot gas entering into the digital scroll compressor from the bypass through the exhaust port during tandem operation, an external check valve is required.
Is a Check Valve Required in the Exhaust Pipe?
For standard single-digital scroll compressors with a capacity below 6HP, no external check valve is required.
However, in a parallel configuration, Miracle recommends installing a check valve in the exhaust line.
Why No Liquid Injection for Compressor?
During a low load operation, the time that the Copeland condensing unit Digital Scroll compressor is in the unloaded state is extended.
The power consumption in the unloaded state is very low, only 10% of the full load power.
This low power consumption does not cause the compressor to generate heat, so there is no need to inject coolant.
Copeland Multi-Compressor Condensing Unit
Except for the open-type Copeland condensing unit and Box-type Copeland condensing unit, Miracle also supplies Copeland parallel condensing unit to meet your requirements. For details, please contact us.
Installation of Copeland Parallel Compressor Condensing Unit
Advantages of using Copeland Parallel Condensing Unit :
1. The capacity can be effectively controlled, and it can be adjusted by starting/stopping the Copeland condensing unit in the group.
2. Improve the reliability and reduce the number of times stopping and opening the Copeland scroll compressor parallel condensing unit compared with a single Copeland condensing unit.
3. The starting load is reduced, and the starting time of each compressor can be separated by the time delay method.
4. Spare function, if one of the compressors is damaged, there is still some capacity for other Copeland condensing units.
Copeland Condensing Unit Use Skills
System matching parameter requirements, basic performance requirements are the same as the single compressor unit system.
In the Copeland condensing unit parallel system, you should pay more attention to the oil return reliability of the system, and the multi-line system.
Oil balance between compressors:
During the oil return process.
There should be no bias flow that causes the lubricating oil to accumulate in one or several compressors while other compressors are short of oil.
A filter screen should be installed at the oil return port.
Temperature and pressure protection switches should be set.
Maintaining the oil level is the most important issue.
Copeland Compressor Unit Oil Analysis
In the Copeland condensing unit parallel scroll system.
Due to the difference between the compressor’s oil volume and the system’s oil return volume.
The long-term operation will cause the compressor’s oil level to change (one oil level decreases and the other oil level rises).
you can see the figure in the following:
When connecting Copeland condensing unit compressors A and B of the same model.
If the oil volume of compressor A is large and the oil return volume in the system should be small.
The oil level of A will continue to drop, and finally.
The Copeland condensing unit compressor will be almost no oil, resulting in poor lubrication and causing bearings to burn.
The oil volume of compressor B is small, and when the oil return volume of the system is large.
The oil level of B will continue to rise, and finally, the motor rotor is almost immersed in the oil, which will cause the increasing situation in input power and temperature rise in various parts.
Solutions to the Oil Partiality of Parallel Scroll Unit
⦁ Connect the Copeland condensing unit scroll compressor with the same model or same capacity.
Try to balance the oil amount and oil return amount.
⦁ The components of each system should adopt the same shape.
Such as the compressor discharge pipe to the confluence part, and the branch part of the compressor suction pipe.
The two compressors should try to maintain the refrigerant flowing and oil flowing evenly.
⦁ In order to further suppress the oil amount in the system, an oil separator is designed on the exhaust pipe so that the lubricating oil that is separated into the two compressors returns to the refrigeration system.
⦁ Carry out oil equalization operation after parallel unit operation for a certain period of time.
The representative oil equalization operation method is to close or open both compressors in a limited time through the following sequence to correct the oil deviation, as shown in the figure below:
⦁ Stop a compressor B (OFF) for 2 minutes: the oil will move to the compressor A (ON) side through the oil equalization pipe.
⦁ Stop compressor A (OFF) for 2 minutes: the oil will move to the compressor B (ON) side through the oil equalization pipe.
⦁ Return to the original operating state Compressor A and Compressor B both return to the operating state (ON).
Tips of Parallel Scroll Copeland Unit
Copeland condensing unit Compressor installation:
It is required to install on the same level as possible; the center distance of the compressor is selected to facilitate the loading and unloading of the compressor.
The layout of piping that is with an accumulator should be as symmetrical as possible.
Copeland condensing unit refrigeration oil separator installation:
It can be equipped with one for each compressor, or it can be installed on the exhaust manifold.
Miracle provides different types of oil separators, such as standard AW series oil separators, AF oil separators, helical oil separators, etc.
If you need to know more about the oil separator, please click on the picture below.
Copeland Condensing Unit Accumulator Installation:
The Copeland condensing unit accumulator generally has two structures:
“One-in, one-out” structure refers to the main inlet pipe and the main outlet pipe and uses a three-way distributor or other distributors to connect the suction pipe of each compressor with the main pipe.
The advantages are: the structure of the Copeland condensing unit accumulator is simple, the manufacturing is convenient, and the versatility is good.
The disadvantage is that a three-way distributor is needed to connect the suction pipe of each compressor.
The splitting effect of the three-way directly affects the suction and oil return of each compressor, and the size of the oil return hole of the Copeland condensing unit accumulator is difficult to balance full open and minimum operation for the oil return.
“One-in, multiple-out” structure refers to one main inlet pipe and multiple outlet pipes.
The advantages are: the return air of each compressor is easier to be uniform, the size of the oil return hole of each pipe is only responsible for the return of oil from one compressor, and the impact on capacity adjustment is small.
In the case of blockage, it only affects one compressor, which is more reliable.
The disadvantages are: complex processing technology, high precision requirements, consistent requirements for the size of each hole, and the installation height of the outlet pipe must be strictly controlled and consistent.
Miracle provides different types of accumulators, such as standard accumulators from 1/2 to 3 1/8, also provide the Copeland condensing unit accumulator with heat exchanger, liquid receiver, suction accumulator with heat exchanger.

Yes, no problem. We are willing to do the most support we can to enlarge your business. Contact us for a talk.
Pressure and Temperature Setting of Copeland Scroll Compressor?
It is very important to monitor the pressure and temperature in the compressor scroll application.
The exhaust line thermostat is required in the scroll compressor of 2HP-6HP.
The purpose is to cut off the refrigeration compressor at 125°C or even below.
The thermostat must have good thermal insulation properties, and the distance from the discharge connector to the Copeland compressor must be kept at 5 inches.
In addition, the high pressure and low pressure of the Danfoss compressor must be well controlled.
The low pressure is mainly used to prevent damage to the compressor caused by high vacuum;
Can the Copeland Scroll Compressor Operate on the Liquids?
The answer is yes, and because of the axial and radial flexibility of Copeland scroll compressors, it can handle liquids better than most compressors.
But must be equipped with necessary accessories;
The accessories for Copeland scroll compressors to operate on liquids include:
For systems with large refrigerant capacity or uncontrollable refrigerant surge conditions, storage and crankcase heaters must be configured;
How to Realize Oil Management in the Copeland Scroll Compressor?
All refrigeration compressors must have an oil management system to maintain the correct oil level in the crankcase.
The oil pump of the scroll compressor has no oil pressure safety control, so the scroll compressor must be equipped with an external oil level controller;
This external oil level controller must ensure that the oil level cannot return to the normal level and cut off the refrigeration compressor;
