Product Description

1.Application of Air Source Heat Pump
Eurostars EVI air source heat pumps are designed for house heating and cooling. User can change the working mode by operating the controller. Compressor starts/stops according to return water temperature. When all rooms reach preset temperature by room thermostat, heat pump will be turned off through linkage switch.
Wide Range of Applications: these EVI low temperature heat pumps could meet the heating and cooling requirements of different places, such as villas, houses, schools, factories, hotels, hospitals, spa centers, sauna centers, greenhouses, flower gardens, farms, etc. 


2.Eurostars Air Source Heat Pump Features:
EVI air source heat pumps are designed for domestic/commercial hot water and house heating in cold areas where lowest air temperature is above -25ºC,They are featured with: 
--- Efficient and Energy-saving 
Air to water heat pumps absorb hot energy from the air freely, while the electricity is only used to drive the compressor to pump up the heat from the air, so they consume just a quarter of power of traditional electric water heaters, saving a lot of electric cost for users.  
---Green and Environmental Protection
By using air source energy and electric power, there is no harmful gas being discharged during the operation of heat pumps. R410A and R407C refrigerant guarantees fluoride-free emission. 
---All-weather Operation
Stable operation without being influenced by windy, rainy or snowy weather. 
---Endurable 
The Enhanced Vapor Injection (EVI) technology from Copeland compressor with crankcase heater for special cold area, famous brand electronic expansion valve, Eaton/ Schneider/FUJI AC contactor and thermal relay as well as other brand components of the heat pump guarantee high product quality and a long lifespan. All of our screws and clips (both external and internal) are rust resistant , stainless steel is optional. The cabinet we are using is made of galvanized steel, making the product more rust resistant and durable.
---Multiple Protections
Eurostars heat pumps with multiple protections: For example, if water flow is not enough in the system, the system will show high pressure protection and stop the heat pump automatically to protect the compressor from being damaged. Also, there is high current protection: if the power supply is not stable, the heat pump will show the high current error to stop the heat pump and avoid compressor damage.
---Guaranteed Safety
Complete isolation of water and electricity avoids electric shock, explosion and poisoning. 
---Convenient: 
EVI heat pumps are easy to install. They can be placed in many places, such as garages, balconies, kitchens, etc.

7.FAQ
Q:When in cold winter, can the heat pump unit work properly?
Of course. Regarding our air source heat pump unit features intelligent auto-defrosting function, which ensure the heat pump to work in the low temperature by sensing the outdoor temperature, evaporator fin temperature and time of working automatically.

Q:Can a heat pump also heat the domestic hot water?
It certainly can, but whilst heating to the high temperatures required, the efficiency reduces. However, even low efficiencies are far better than an electric immersion heater. Most of the latest heat pump units have the hot water function built in, so it is usual to use this facility.
As the insulation levels in buildings increases, the room-heating demand drops, but the hot water demand is, if anything, increasing. It is therefore becoming more important to optimise the hot water facility. i.e. the size and design of the hot water cylinder is very important.

Q:Why it can work at -25ºC?
Because of the Enhanced Vapor Injection (EVI) technology from Copeland compressor, EUROSTARS designed EVI gas piping system and controlling system, make EVI air source heat pump can work stably in the low temperature condition.

10.Installation instruction or installation photo, project photos


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.
