All in one air source domestic heat pump for heating and hot water

Product application:

* Hot live water for shower all the year around

* House heating in winter

Product Description:
This series adopts high efficiency tube-in-shell heat exchanger and built-in water pump inside the heat pump, which ensures not only high efficient performance of the system but also easy installation. It can supply domestic hot water and house heating with underfloor heating,fan coil units or radiations.
The heat pump can control the three valves to realize the switching between sanitary hot water and heating.

1. DAISHIBA Scroll Compressor:
1) The volume efficiency is high: scroll compressor adjacent to the crescent-shaped space between the small pressure, less leakage, no suction and exhaust valve, the resistance is small, no clearance volume re-expansion
2) High insulation efficiency: In the case of the same cooling capacity, the vortex compressor is about 10% higher than the reciprocating type.
3) Small noise and small vibration.
4) Copeland Compressor: has a solid cast iron body to provide a large cooling area to improve the cooling effect of the compressor, and the use of lightweight aluminum piston to reduce friction and vibration, with cutting-edge electronic protective film block, can provide a comprehensive motor protection.
2. Water pump built in : Circulating heating
3. Automatic Defrosting : When the ambient temperature reaches the protection temperature set by the heat pump, the heat pump will automatically turn on the protection mode, play a protective role
4. Intelligent control : You can download the air source heat pump control the software, you can freely adjust the temperature you want, convenient and fast
5. Safe,Reliable,Stable Running : Pollution-free, energy saving, reliable technology
6. Low Noise & Vibration : Use sound insulation cotton to reduce the heat pump itself noise and vibration
7. Long working life : DAISHINA  Sheet metal use thickened stainless steel or galvanized, high quality, life can be as long as 10 years

How does a heat pump work?

Heat pump uses electrical energy and take low grade heat energy from the outdoor air to heat refrigerant which in turn heats water for domestic use and space heating. The efficiency of a heat pump is known as the coefficient of performance or COP. This is a ration of the heat delivered to power consumed.

At the beginning of the first phase the refrigerant is cold low pressure liquid.

1. The refrigerant passes into the evaporator and heat energy from the outside air passes over the evaporator causing the refrigerant to increase in pressure and change to warm vapor.

2. This warm vapor then enters the compressor as it passed across one side of a plate heat exchanger, and this is transferred via the pimary water circuit to heat up the water tank.

3. The hot refrigerant gas is the temperature, the cool vapor still has a high pressure and to reduce this pressure the vapor passes through an expansion valve. This cause the pressure to drop and the temperature lowers, returning the refrigerant to its initial state of cool low pressure liquid.

This process is repeated.

It is only the refrigerant that passes through this cycle; the water is heated as it travels tthrough the plate heat exchanger. The heat energy from the refrigerant passes through the plate heat exchanger to the cooler water which increase in temperature. This heated water enters the home heating circuit and also be used to provide domestic hot water via a hot water tank.
