Working method of a heat pump

Abstract

The operating principle of the air-source heat pump is based on the physical property that the boiling point of a fluid increases with pressure. A heat pump has four main components: evaporator, compressor, condenser and expansion device. The examined heat pump is used for making domestic hot water and air condition. Decreasing energy resources of the Earth and enhanced energy consumption are typical of our life. However, one of the basic conditions to survive is that the amount of the energy used every day should be reduced. The energy used to air-condition a room and the possible use of secondary energies generated by the air-conditioning is studied in the research. The heat energy distracted by a heat pump out of the room is not let outside as heat loss, but it is used for making domestic hot water. The efficiency of the heat pump is examined with varied air parameters inside. About 0.3 kW electric power taken by heat pump from national electricity network. Heat pump can be separated from united electrical network by solar energy system; this article shows solution for this method too.
