1. Air source heat pump unit belongs to medium-small units, suitable for buildings of 200-10000 square meters.

2. Air conditioning system enjoys all-in-one cooling and heating sources, suitable for users have simultaneous demands on heating and cooling, at the same time free from the need for boiler room.

3. Outdoor unit installation reduces the need for refrigeration room and saves the construction investments.

4. The primary energy ratio of air source heat pump unit is up to 90%, saving energy consumption, significantly reducing users' costs.

5. There is no need for cooling towers, cooling water pumps and piping, reducing investments in additional equipment.

6. There is no power consumption of cooling water system, no water loss, suitable for the water-deficient are

Heat pump water heaters are the automation devices, if conduct the daily maintenance when using, the working life and stability of the units will be guaranteed. 

1. We should set the outlet water temperature according to the factory settings. The best energy saving water outlet temperature is 46-52℃。

2. The filters installed outside should be cleaned regularly to ensure the clear water quality inside the system and to prevent the breaking from the blocking.

3. All the protection devices have been set before delivery, personal adjustment is not allowed.

4. Check regularly if the connection between the power supply and the electric system is tight. If there is something wrong with the electric system, we should maintain and change it in time.

5. Don’t turn on/off the units by pulling the plug directly, and check the leakage protection at regular time.

6. Check if the water compensation, safety valves and air exhausting device are in normal condition to ensure the heating capacity and operation stability..

7. Check if there is leakage existed in water pipe connection.

8. Environment outside the units should be dry and clean, and cleaning the heat exchangers every 3-6 months to ensure the heat exchange efficiency.

9. Check every part of the units to ensure there is no gas leakage and no refrigerant leakage.

10. If power off the units for a long time, it’s better to discharge all the water and power off the units. Before restart the units, complete inspection is necessary.

11. If there is some noise from the units when restarting, check carefully to exclude the obstacle.

12. If there is something wrong with units and we can’t solve them by ourselves, it’s better to inform the after sales service of the factories.

 

Heat pumps use a small amount of driven electricity to absorb heat and transport it from one place to another. Indeed, they couldn’t generate heat. 

As swimming pool’s water circulated by the pool pump, the water get from the pool passes through a filter and pool heater. The pool heater has a fan that brings in the outside air and guides it over the evaporator coil. Liquid refrigerant within the evaporator coil absorbs the heat from the outside and then evaporate gas. The evaporated gas in the coil then flows through the compressor. The compressor pump to increase the heat, generate a very hot gas that then flows through the condenser. The condenser moves the heat from the hot gas to heat the cooler pool water circulating through the heater. The heated water then flow into the pool. The hot gas, as cross flows through the condenser coil, back to liquid form and return the evaporator, where the whole process begins again. 

Higher efficiency heat pump pool heaters usually use scroll compressors versus the rotary compressors of standard composition. 

Heat pump pool heaters work efficiently as long as the outside temperature remains above the 7.2℃–10℃ range. The cooler the outside air they bring in, the more energy they exhaust. However, since most people adopt outdoor swimming pools during summer or mild weather, this usually isn't an issue.
