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. 3.2 Air source heat pump working principle 4 way valve Fa n un i t Water inlet Condenser Ev ap or a to r Water Outlet Gas-liquid separator Compressor Filter Filter Expansion valve Figure 1 Qc (Heat energy get) =Qa (Compressor consumption) +Qb (Heat energy absorbed from ambient environment) -7- 4.

Adjusting and Initial operation 9.1 Attention ● Within 12 hours after running, please connect the circuit breaker, and make the crankcase heater be preheated. ● 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. - 40 - ● 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 - 41 - 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. ● Remove the compressor air suction and exhausting pipe. ● Remove the compressor power cables. ● Remove the compressor fixing screws. ● Remove the compressor. 10.5 Conduct regular maintenance according to the user manual instruction, to make sure the unit running in good condition. ● Fire prevention: if there is a fire, please turn off the power switch immediately, put the fire out with fire extinguisher. ● To prevent flammable gas: the unit working environment should stay away from gasoline, ethyl alcohol and other flammable materials, to avoid explosion accident. - 42 - ● Malfunction: if malfunction occurs, should find out the reason, eliminate it and then reboot the unit. Never boot the unit forcibly if the malfunction has not been eliminated. If refrigerant leakage or frozen liquid leakage, please turn off all the power switch, if the unit can not stop buy controlling switch, please turn off the general power switch. ● Never short connect the wire for protection required device, or else, in case unit malfunction, it can not be protected normally and will damage the unit. 11.
