Energy storage type air conditioning unit

Abstract

The invention provides an energy storage type air conditioning unit, which comprises an air source, a phase change heat pool heat exchanger, a fin tube heat exchanger and an air conditioning heat exchanger, wherein an exhaust end of a compressor is fixedly connected with a first four-way valve, four through holes of the first four-way valve respectively communicate with the compressor, the air conditioning heat exchanger, a second four-way valve and the air source, and four through holes of the second four-way valve respectively communicate with the first four-way valve, the phase change heatpool heat exchanger, the fin tube heat exchanger and the air source; the pipeline of the air conditioner heat exchanger is fixedly provided with a first throttle valve, the pipeline of the fin tube heat exchanger is provided with a second throttle valve, and the pipeline of the phase change heat pool heat exchanger is provided with a one-way valve. The energy storage type air conditioning unit overcomes the defects of the prior art, reduces secondary heat exchange by combining a phase change material and a heat pump heat exchanger, so that the energy efficiency of the system is improved by 10%or above; the combined production and supply of an energy storage unit and an installed machine can be realized, a fluorine system is in a single heating operation mode, and a water system is used for combined supply.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an energy storage type air conditioning unit. Background technique [0002] The air source has the characteristics of flexible installation, low initial investment, etc. Compared with the traditional heating method, it has the advantages of energy saving, so it can be widely used. Although the air source has obvious advantages and is widely used, the traditional air source has shortcomings such as frosting and the air temperature cannot be too low, which leads to the air source not being able to exert the advantages of energy saving. The compression ratio of the unit is too large, and the unit cannot operate normally. In order to make up for the shortcomings of the air source, the energy storage technology is used to transform the air source, which can usually improve the heating efficiency of the air source at low temperature, and has a good energy-saving effect under ...
