Heat Pump Unit Working Principle

Air Source Heat Pump Working Principle

The heat pump works by absorbing heat energy from the ambient
environment and transferring it to the water. It uses a 4-way
valve, compressor, filter, gas-liquid separator, expansion valve,
condenser, and evaporator fan unit to achieve this process.

The formula for heat energy gained (Qc) is:

Qc = Qa (Compressor consumption) + Qb (Heat energy absorbed from
ambient environment)

Heat Pump Performance Curve for Variable Working Condition

The heat pump’s coefficient of performance (COP) is variable
depending on the working condition.

3. Heat pump unit working principle
3.1 Heat pump working process First, the low pressure and superheated gas in the evaporator is inhaled into the compressor then becomes the high temperature and high pressure overheated vapour. Second, the overheated vapour is exhausted into the condenser and exchange the heat with the water, then the refrigerant is condensed and becomes the saturated or over cooling high pressure and high temperature refrigerant liquid. The water is heated up by heat pump when absorbing the heat energy which released by the refrigerant. Third, the refrigerant liquid releases the pressure by passing the expansion valve, then becomes the low temperature and low pressure liquid. Fourth, the refrigerant liquid flows into the evaporator and absorb the energy from the air, then is vaporized and became the low pressure and overheated vapour. The refrigerant working repeatedly as described above, then the water which flows through the condenser is heated up constantly, the temperature rise and can get the hot water.

8.2.4 Control Output 1) Water temperature control Normal water temperature control can be performed when the controller is turned on. Heating mode: When the water tank (inlet water) temperature set temperature ­return difference, heating begins; When the water tank (inlet water) temperature the set temperature, the heating is stopped; Cooling mode: When the water tank (inlet water) temperature set temperature + return difference, the cooling starts; When the water tank (inlet water) temperature the set temperature, the cooling stops.
2) Circulating pump control (water circulation heat pump): When defrosting, water pump is forced to run. When cooling or heating, it is turned on 10 seconds before the compressor and stops 30 seconds after the compressor. Antifreeze mode: When the controller is powered on, whether heat pump is off or on, when the ambient temperature is too low, water pump will enter antifreeze mode to prevent the circulation line or the water tank from freezing. The specific conditions for enabling and disabling the environment for low temperature antifreeze are as follows: a. When the ambient temperature is 35 , and the duration of the circulating water pump is off for more than 30 minutes, the circulating water pump is forcibly started for 60 seconds; b. Exit the antifreeze mode when the ambient temperature rises to 39 . c. When the ambient temperature sensor is faulty, it is mandatory to start the circulating water pump periodically, and run for 60 seconds every 30 minutes.
8.2.5 The Alarm 1) Low pressure fault: After the compressor running for 5 minutes, if the low pressure switch is detected to be in the off state for 10 consecutive seconds, the compressor immediately stops running. At this time, the controller displays the low pressure fault alarm code “04E”. If the low pressure switch is restored, error code does not occur. If no other protection or locking occurs, the compressor is restarted after 3 minutes. If low pressure fault protection appears 3 times within 1 hour, the controller will lock the protection. And the compressor will lock in the shutdown protection state. At this time, only the shutdown and restarting can unlock the compressor. The low pressure switch is not detected during the defrosting.
2) High pressure failure: After the compressor is started, if the high pressure switch is detected to be in the off state for 10

seconds, the compressor immediately stops running. At this time, the controller displays the high pressure fault alarm code “03E”. If the high pressure switch is restored, error code will not occur. And if no other protection or locking occurs, the compressor is restarted after 3 minutes. If high pressure fault protection appears 3 times within 1 hour, the controller will lock the protection, and the compressor will be locked in the shutdown protection state. At this time, only the shutdown and restarting can unlock the compressor. 3) High exhaust temperature failure: After the compressor starts running for 1 minute, when the exhaust gas temperature is detected to be higher than or equal to the exhaust high temperature protection value by 230 for 10 consecutive seconds, an high exhaust temperature alarm occurs and the compressor stops. At this time, controller shows high temperature fault alarm code “02E”. When the exhaust temperature drops back to 194, the alarm is released and the normal temperature control function is restored. If high temperature fault protection appears 3 times within half an hour, the controller will lock the protection. And the compressor will be locked in the shutdown protection state. At this time, only the shutdown and restarting can unlock the compressor.
4) Water flow failure (water cycle model): After the circulating water pump starts, it detects that the water flow switch is in the off state for 10 seconds, then heat pump stops. At this time, the controller displays the water flow switch fault alarm code “01E”.Periodically (1 minute) restarts the water pump and 10 seconds later, the flow switch is detected. If water flow switch is closed, heat pump will goes to normal running. If the fault occurs 3 times within 1 hour, the fault is locked and heat pump will not starts.
6) Low ambient temperature protection: When the ambient temperature is 15.8, the compressor is prohibited from running. When the ambient temperature is 19.4, normal operation is resumed, This protection has no fault display.
7) Water temperature too low protection at cooling mode(water cycle heat pump) In the cooling mode with compressor running for 5 minutes, if detects that the outlet water temperature is <41 for continuous 5 seconds, heat pump enters subcooling protection. The compressor and the fan stop running, And the water pump operates normally. When the outlet water temperature is detected to be 44.6 , heat pump exits the subcooling protection and enters normal operation.
8) Water temperature too high protection at heating mode (water cycle heat pump) In the heating mode, after compressor running for 5 minutes, if the water temperature is detected by continuous 5S 149, it is judged that the outlet water temperature is too high. It will shutdown heat pump for protection and when the outlet water temperature is detected to be 140 , the protection is withdrawn. 9) Temperature sensor failure: Heat pump will stop once the water tank temperature sensor or outlet water temperature sensor or ambient temperature sensor is faulty. When absorb or exhaust or evaporator coil or water return temperature sensor is faulty, electric heater is allowed to operate.

When the return water temperature sensor fails, the return pump is allowed to run (do not judge the return water temperature) When the water tank or ambient temperature sensor are faulty, electric heating operation is not allowed. “11E”, “12E”, “13E” “, “14E”, “15E”, “17E”, “18E”, “19E”. are correspondingly displayed when the coil temperature sensor, ambient temperature sensor, exhaust temperature sensor, inlet water temperature sensor/tank temperature sensor, absorb temperature sensor, and outlet water temperature sensor/return water temperature sensor are faulty.

10. Other: “09E” is displayed when the communication between the main control board and the wire controller is abnormal or the data line is not connected normally. “–:–” is displayed when the valid clock cannot be obtained. And the communication indicator of the main control board flashes. The buzzer sounds when an alarm occurs. Press any key to silence the alarm. The fault code table is as follows:

9. Adjusting and Initial operation
9.1 Attention Within 12 hours after running, please connect the circuit breaker, and make the crankcase heater be pre-heated. Open the valve of water system, and the valve of assistant tank, inject water into the system, and exhaust air inside. Do adjustment after electrical safety inspection. After the power is switched on, start the test running of heat pump, to see if it can function well. Forced operation is forbidden, because it is very dangerous to work without protector. 9.2 Preparation Before Adjustment The system is installed correctly. Tubes and lines are putted in the right place. Accessories are installed. Ensure the smooth drainage. Ensure the perfect insulation. Correct connection of ground lead. The supply voltage can meet the requirement of rated voltage. Air inlet and outlet function can work well. Electrical leakage protector can work well. 9.3 Adjustment Process Check if the switch of the line controller can work well. Check if the function keys of the line controller can work well. Check if the indicator light can work well. Check if the drainage system can work well. Check if the system can work well after starting up. Check if the water outlet temperature is acceptable. Check if there is vibration or abnormal sound when the system is functioning. Check if the wind, noise and condensate water produced by the system affect the environment around. Check if there is refrigerant leakage. If any fault occurs, please check the instructions first, to analyze and remove the fault.

10. Operation and maintenance
10.1 Personals shall possess professional knowledge or operate according to professionals from our company. To ensure the well functioning, the system shall be checked and maintained after a period of time. During the maintenance, please pay attention to some points below:
Control and protect the equipment, please do not adjust any settings discretely.
Pay close attention to whether all the operation parameters is normal during system working.
Examine regularly whether the electrical connection is loose, if yes, fasten it on time.
Examine regularly the reliability of the electrical components, change all the failed or unreliable components on time.
There will be calcium oxidized or other mineral substance deposition on the surface of water heat ex-changer copper coil after long period of operation, which will influence the heat exchange performance and lead to high electrical consumption, discharge pressure increasing and air suction pressure drop, unit hot water volume produced is less. We can adopt formic acid, citric acid, acetic acid or other organic acid to clean.
The dirt retention on the surface of evaporator fin should be blowed by more than 0.6Mpa compressor air, brushed by fine copper wire, or flushed by high pressurized water, usually one time per month; if too much dirt, we can use paintbrush dipping gasoline to clean.
After long downtime, if we restart the equipment, we should make following preparations: examine and clean the equipment carefully, clean the water pipeline system, examine the water pump, and fasten all the wire connections.
Replacement parts must use our company original accessories, can not be replaced by other similar accessories.
10.2 Refrigerant filling
Examine the refrigerant filling condition through reading the data of liquid level from display screen, also the air suction and exhaust pressure. If there is leakage or changing components of the refrigeration circulation system, we have to make air tightness examination first.
10.3 Leak detection and air tightness experiment:
During leak detection and air tightness experiment, never let the refrigeration system filling oxygen, ethane or other flammable harmful gas, we can only adopt compressed air, fluoride or refrigerant for such experiment.
10.4 To remove the compressor, please follow the following steps
Turn off the power supply

Exhaust the refrigerant from the low pressure end, attention to reduce the exhaust speed, and avoid frozen oil leakage.
