Triple supply method capable of implementing refrigeration, heating and heat water supply functions

Abstract

The invention relates to a combined function method for realizing multiple functions of refrigeration and heating and the like. A tri-supply method for realizing refrigeration, heating and hot water supply of the invention integrates a solar-cooling-tube refrigerating system, a trans-critical CO2 heat-pump circulatory system and a hot water circulatory system. The combined function method of the invention, by combining a solar-cooling-tube absorption refrigerating system and a trans-critical CO2 heat-pump system and integrating the strength of the two independent system to recover the defects of each system, can meet the demands of refrigeration in summer and heat supply in winter as well as the demands of hot water supply all year round, and has not only great strength on environmental protection, but also promising potential of energy conservation. The combined function method, which integrates a heat-pump air-conditioner and a hot-water-supply system in one body, not only ensures the compact structure in the implementation of the whole method, but effectively increases utilization rate of equipment.

Description

technical field [0001] The invention relates to a combined function method capable of realizing multiple functions such as refrigeration and heating. Background technique [0002] Due to the increasingly serious environmental problems such as global warming and climate anomalies, and the gradual depletion of conventional primary energy sources (such as oil, coal, etc.), environmental protection, energy conservation and the search for new energy sources have become major and urgent issues for the entire international community. [0003] At present, the freon household heat pump air-conditioning system widely used in summer has a large amount of heat released by the outdoor condenser, forming local heat pollution, and the higher the outdoor temperature, the lower the cooling efficiency and the higher the energy consumption; in the transitional season in the north or in winter in the south, When the outdoor temperature is low, the heating efficiency of the heat pump is very low...

Problems solved by technology

[0003] At present, the freon household heat pump air-conditioning system widely used in summer has a large amount of heat released by the outdoor condenser, forming local heat pollution, and the higher the outdoor temperature, the lower the cooling efficiency and the higher the energy consumption; in the transitional season in the north or in winter in the south, When the outdoor temperature is low, the heating efficiency of the heat pump is very low, and an auxiliary electric heating device needs to be added to meet the demand, and the energy consumption is also greatly increased; in addition, with the improvement of people's living standards, the demand for domestic hot water is also increasing. The bigger it is, the energy consumption it needs accounts for about 30% of the total energy consumption of the household. Generally, electric heating or gas heating is used to make hot water. The air conditioning system and hot water supply system are set up separately, so the equipment utilization rate is low and the cost is high.
