Electric-energy-storage high-accuracy air conditioning equipment using low-grade heat source heat pump

Abstract

The invention relates to electric-energy-storage high-accuracy air conditioning equipment using a low-grade heat source heat pump. The equipment comprises a low-grade heat source, an adsorption-type heat pump, a heat energy storage device and an air conditioning system. The heat energy storage device comprises a heat-electricity conversion device and an electric energy storage device. The air conditioning system is a compression-type air conditioning system. The low-grade heat source is converted into a high-temperature heat source through the adsorption-type heat pump, then the high-temperature heat source is converted into electric energy through the heat-electricity conversion device, the electric energy is supplied to the air conditioning system and excessive electric energy is stored in the electric energy storage device for future use. The electric-energy-storage high-efficiency air conditioning equipment using the low-grade heat source heat pump has the advantages that since the heat energy is converted into the electric energy through the heat-electricity conversion device and then the electric energy is stored, the electric energy density is improved and the occupied space is saved; since the electric energy is used for driving the ordinary compression-type air conditioning system, the precise control of an air conditioner is easy to realize and the use requirements of places which have higher requirements on the air conditioner can be met; since a sensor is used for measuring the internal parameters of the adsorption-type heat pump and the adsorption conversion frequency of adsorbing agent is controlled, the conversion process can be shortened and the working efficiency of the heat pump is improved.
