R410a Series
Circulating heat pump,Standard Inlet water 50℃, outlet water 55 to 60℃.
The temperature differential is 5 to 10℃.
R410a is used widely in living, commercial, industry and agriculture.
Atmosphere heat + high efficiency electric transference is the best heating device. Closed circulating heating system can save water storage tank size by keeping hot water in different layer.
In low temperature environment (-5℃ to 40℃), the normal living uses 60℃ water. R410a is very suitable for this requirement.
Ⓞ Analysis of Energy Saving Theory
Heat Pump hot water machine is driven by electrical power. The electricity is used to drive the heat pump to absorb the heat from external environment and release the heat to water. The electrical power is not used as electric heater to generate 860Kcal in a kilowatt hour.
In electrically powered heat pumps, the heat transferred can be three or four times larger than the electrical power consumed, giving the system a Coefficient of Performance (COP) of 3 or 4, as opposed to a COP of one of a conventional electrical resistance heater, in which all heat is produced from input electrical energy.
The heat pump drive compressor to transfer heat instead of heating the water by electric heater. Heat pump is used to provide heating because less high-grade energy is required for their operation than appears in the released heat. Compare to the electrical power boiler, it can save two of three cost.
Ⓞ Energy Saving Theroy
● Less electrical power drive the heat pump.
● Compressor-driven refrigerant transfer huge free heat from air QL
● Cold water is heated inside the machine get the energy We.
The law of conservation of energy:
Standard work: QL=WE then QH= QL+WE> WE
Coefficient of Performance(COP) = 4.3
Input Energy / Output Energy COP=QL/WE
That means consume 1kw electrical power can gain 4.3 kw heat energy.
