Product Description

1.Application of Air Source Heat Pump
--Heating, ventilation, and air conditioning
In heating, ventilation, and air conditioning (HVAC) applications, a heat pump is typically a vapor-compression refrigeration device that includes a reversing valve and optimized heat exchangers so that the direction of heat flow (thermal energy movement) may be reversed. The reversing valve switches the direction of refrigerant through the cycle and therefore the heat pump may deliver either heating or cooling to a building.

--Water heating
In water heating applications, a heat pump may be used to heat or preheat water for swimming pools or heating potable water for use by homes and industry. Usually heat is extracted from outdoor air and transferred to an indoor water tank.

--District heating
Heat pumps can also be used as heat supplier for district heating. Possible heat sources for such applications are 
sewage water, ambient water (like sea, lake and river water), industrial waste heat, geothermal energy, flue gas, waste heat from district cooling and heat from solar heat storage.

--Industrial heating
There is a great potential to reduce the energy consumption and related greenhouse gas emissions in the industry by application of industrial heat pumps.

5. EUROSTARS Heat Pump Range:
Based on the "Reverse Carnot Cycle" principle, air to water heat pump is a type of air source heat pump (ASHP), which utilizes energy from the air to generate heat and provide domestic/commercial hot water, house heating and/or cooling. At the same time, ASHPs are among the most efficient heat pumps on the market, since they consume the least energy to complete the above requirements. And they are becoming more and more popular among households and businesses with their guaranteed safety, eco-friendliness, long service life and many other advantages. The service life of an air to water heat pump can usually reach 15 to 20 years.

7.FAQ
Q:What is the Daily Maintenance for Heat Pump Water Heaters?
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 46-52ºC.
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.

A,Place selection of installation Heat pump
 1). Heat pump should be installed in a large space, and have good air flow condition.
 2). Air inlet and outlet must be a clear road, the distance from barrier to inlet and outlet must be longer than 2m.
 3). Set drain ditch or drain outlet, so that can drain water easily.
 4). The installation base or bracket must be firm, make sure heat pump work balancely.
 5). Make sure heat pump is vertical, can't be slanted.
 6). Don't install heat pump at the place in where there is plenty of pollutional and corrosive gas or sand or fallen leaves.
 7). The installation place can't be near inflammable, flammable thing or fire.
 8). Installation:
---The installation base can be concrete construction, or steel bracket, and must use anti-vibration rubber pad, And the surface should be smooth.
---The design of installation base can be according to heat pump weight.
---The heat pump bottom should be fixed by bolt.
B,Pipe connection
The drain pipe and overflow pipe should be installed near drain ditch or drain outlet, easy to drain, and install drain water valve on drain pipe before magnetic valve there should be service valve on water pipe.
 If use plastic pipe (such as PPR pipe or ABS pipe), users should consider pipe expand and contract problem between heat pump and water tank.
 Water supply valve and cut-off valve maybe need insulation (according to local weather condition),avoid frost crack.
C,Water pipe system installation
Water pipe should be straight, and the arrange should be reasonable, reduce bend as little as possible. Reduce the water pipe resistance.
There can't be leaking at any place of pipe.
After all equipments and pipes installation finished, users should test water pressure, and drive air out, drain dirty out, make sure water cycle system is  clean. After confirm there is not any problem, then insulate all hot water pipes.
D,Power supply wiring
 220V heat pump use single phase power supply, 380V heat pump use three phase power supply, wire line is 3phase 4lines, A B C connects live line, N connects null line, E connect earth. Be sure not to connect N line to live line of power supply.
 1).When repairing, please turn power supply at "off" side.
 2).Power supply connecting process:make sure a equipment power supply is cut off before its installation is finished. Install power supply switch at suitable place, Use rubber hole for wiring line in electric box.
Power supply demand:
220V rated voltage±10%
380V rated voltage±10%
frequency:50Hz rated frequency±2%
 3).if power supply fluctuation is out of demand, please don't start your heat pump.
