Multifunctional solar auxiliary air conditioning system

Abstract

The invention discloses a multifunctional solar-assisted air-conditioning system. The multifunctional solar-assisted air-conditioning system comprises two parts of a refrigerant circulating system and a water circulating system, wherein, the refrigerant circulating system comprises a compressor, an indoor heat exchanger, a refrigerant-water heat exchanger, an outdoor heat exchanger, a high pressure liquid storage barrel, a throttling device, a three-way valve, an one-way valve and a gas-liquid separator which are sequentially connected; and the water circulating system comprises a solar heat collection device, a water tank, a water pump and the refrigerant-water heat exchanger which are sequentially connected. The multifunctional solar-assisted air-conditioning system of the invention can high efficiently realize the functions of a cool-warm air conditioner and a water heater, thereby having very strong energy-saving property, practicality, economy and broad market prospect. The multifunctional solar-assisted air-conditioning system is particularly applicable to the occasions which are rich in solar energy resources and simultaneously need the cool-warm air conditioner and the supply of hot water.

Description

technical field [0001] The invention belongs to the fields of heat pump air conditioners, heat pump water heaters and solar energy utilization, and in particular relates to a multifunctional solar energy auxiliary air conditioner system. Background technique [0002] The oil crisis and the greenhouse effect have posed severe challenges to the world in terms of energy and environment. It is estimated that, according to the current rate of exploitation and use, within 50 to 60 years, oil, coal, and natural gas will be exhausted, and the human energy use system will be updated to an energy system dominated by solar energy. The heat pump technology known as "heat multiplier" can transfer a large amount of low-grade heat with less high-grade energy, and is an application technology that efficiently utilizes high-grade energy. Combining the utilization of solar energy with the application of heat pump technology is very conducive to the rational use of natural resources, while im...
