What is a Pump?

The so-called pump is a device to concentrate the decentralized material and improve their bit energy. Heat is not material, but can, Hot concentration and increase the bit energy must be achieved through the carrier, the carrier is refrigerant. Heat pump is using of a small amount of high-grade electrical energy as a driving source of energy from the low-temperature scattered heat source to absorb low-grade heat and transfer to high-temperature heat source to achieve the pump heat purpose.

What is a Heat Pump?

Steam compression heat pump is currently the most common application of heat pump. This heat pump system works as below: the refrigerant is evaporated in the evaporator after absorbing heat, after evaporate into super-heated steam into the compressor, the refrigerant will be compressed into high temperature and pressure of the gas in the adiabatic compression of compressor. Then the condenser constant pressure condensed into low temperature and high pressure liquid, the liquid refrigerant flow past the throttle to become low-temperature low-pressure liquid, and then enter the evaporator to constant pressure endothermic, and then cycle back and forth. Heat pump water heater is transfer the heat in the air to water we need.

Heat pump technology is a technology to improve the energy grade, it is not the energy conversion process, so the energy conversion efficiency is not limited to 100% limit, but to comply with the inverse Carnot principle. The heat transfer coefficient of the heat transfer coefficient is also known as the Coefficient Of Performance (expressed in COP).Air source heat pump hot water equipment, the core technology is the energy efficiency ratio of COP value, selected air source heat pump hot water equipment, an important indicator should also be the size of COP value,when the energy efficiency ratio COP value is greater, means more energy-efficient.
