Questions and answer:

1. What is kind of swimming pool heat pump water heater ? 

The device is a kind of all new production of hot water equipment, it will absorb heat from the air heating water to a maximum of 55°C. DAISHIBA swimming pool heat pump collective type with hot water, heating unit and villas, family, beauty parlor, small, with hot water heating unit. 

2. Low air temperature so how can put it the water heated to a temperature of 55°C? 
Usually, we always think that heat from the hot reservoir flow to the low temperature heat source, and only under 45°C, the temperature of the air especially cold winter if you want to use air directly heated water is impossible.But DAISHIBA swimming pool heat pump water heater with a compressor, through the input power, compressor power, can realize from the low temperature heat in air and translated into the process of high temperature heat, and by using high temperature heat heating water to 55 to 60°C. 

3. Swimming pool heat pump water heater need electricity, operation cost will very high? 
DAISHIBA swimming pool heat pump water heater is different from the electric water heater, electric water heaters are electric heating tube converts electrical energy into heat energy to heat the cold water directly, the electric conversion efficiency for around 95. But air heat pump water heater power is consumed by a heat pump work, only have the effect of prompting HTM circulation movement, due to the large amounts of heat from the air into the system, the consumption of energy is more than heat pump for hot water electricity and the ratio of the two energy can reach more than 4 times, namely high electro-thermal conversion rate reached more than 4 times.

How Does a Heat Pump Work?

Heat pumps use 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 where its temperature increase as a result of the compression process and turns into a hot gas.

3. The hot refrigerant gas is then condensed as it passes across one side of a plate heat exchanger, and this is transferred via the primary water circuit to heat up the water tank.

4. Despite dropping in 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 through 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.
