Problems solved by technology

However, this system uses a throttling element to realize the flow adjustment of all functional modes, which is only suitable for throttling elements with adjustable opening such as electronic expansion valves, not suitable for capillary tubes as throttling elements
In addition, the system uses many electric valves, which are costly and difficult to control.

Abstract

The invention discloses a indirect-expansion multifunctional solar energy auxiliary air condition system, comprising a refrigerant circulation system and a water circulation system wherein the refrigerant circulation system comprises a compressor, an indoor heat exchanger, a refrigerant-water heat exchanger, an outdoor heat exchanger, a high-pressure solution storage barrel, a throttling device, a three-way valve, an one-way valve and a liquid-vapor separator which are connected in turn and the water circulation system comprises a solar energy collection system, a water tank, a water pump and a refrigerant-water heat exchanger. The indirect-expansion multifunctional solar energy auxiliary air condition system uses a very simple way, a new bridge module with a high-pressure solution storage barrel, a one-to-one connection method of three throttling elements and three heat exchangers and only two electric valves to realize the various function modes of the cold-hot air conditioner and water heater, therefore the cost and control difficulty is greatly reduced. The indirect-expansion multifunctional solar energy auxiliary air condition system is very suitable for the occasion with rich solar energy resources and in need of cold-hot air condition and hot-water supply.

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 an in-expansion multifunctional solar auxiliary air conditioner system. Background technique [0002] Solar energy is an inexhaustible source of energy for human beings. The combination of solar energy and heat pump technology is an important direction for alleviating the current global energy shortage and realizing energy conservation and emission reduction. The indirect expansion (referred to as inter-expansion) solar-assisted heat pump is a combination of solar energy and heat pump technology with the longest history. It supplements solar energy to the side of the heat pump evaporator through water or other heat-carrying fluids, and realizes it by increasing the evaporation temperature. Heat more efficiently. In recent years, the rapid development of solar water heater technology has provided a broad ...
