Abstract

The embodiment of the invention discloses a solar air conditioning system as well as a control method and a control device of the solar air conditioning system, relates to the technical field of a solar air conditioner and aims to solve the problems that a compressor of an existing solar air conditioning system works for a relatively short time under a frosty working condition and needs to be started or stopped frequently. The solar air conditioning system comprises a coolant circulating loop, a solar heat collector, a thermal storage device and a coolant circulating branch, wherein the coolant circulating loop comprises a compressor, a four-way reversing valve, an indoor heat exchanger, a first throttling device and an outdoor heat exchanger which are connected in sequence; the solar heatcollector is connected with the thermal storage device; a first end of the coolant circulating branch is connected between the first throttling device and the outdoor heat exchanger; a second end ofthe coolant circulating branch is connected with an air sucking opening of the compressor; a first electromagnetic valve is arranged on the coolant circulating branch; and the coolant circulating branch positioned between the compressor and the first electromagnetic valve is connected with the thermal storage device. The solar air conditioning system disclosed by the invention can be applied to indoor temperature regulation.

Description

technical field [0001] The invention relates to the technical field of solar air conditioning, in particular to a solar air conditioning system, a control method and a control device for the system. Background technique [0002] As a clean and environmentally friendly energy source, solar energy has been widely used in various industries. At present, there are mainly two types of solar air-conditioning systems in China. One is to use solar heat as the heat source of the absorption refrigeration system generator to achieve cooling. However, when the temperature of the solar collector is low, the efficiency of converting solar heat into absorption refrigeration The other way is to use solar photovoltaic power generation, and use the generated electric energy to drive the compressor of the vapor compression refrigeration system, and its conversion efficiency is also low. Due to the instability of solar energy itself and the low energy conversion efficiency, the solar air-condi...
