Solar energy-air source energy-storage type solution heat pump device

Abstract

The solar-air source energy storage type solution heat pump device is a solar-air source energy storage type solution heat pump cooling and heating method with energy storage function based on water cooling and refrigeration in summer, absorbing heat from the air with the help of solution in winter and making full use of solar energy. It is a device for realizing this method, which includes a refrigerant circulation circuit, a solution circulation circuit and an air circulation circuit, and is mainly composed of a cold and hot water unit, a cooling tower, a solar heat collector, a solution regenerator, a concentrated solution reservoir, a dilute solution The main components such as the reservoir. In summer, the device can realize the function of water-cooled chiller, use the cooling water to evaporate and absorb heat in the cooling tower, cool the refrigerant of the unit, and produce cold water; in winter, use the solution to exchange heat with the air in the cooling tower, The heat absorbed is used by the unit to make hot water, which completely solves the inevitable frosting problem of the existing air source heat pump during heating operation in winter, and improves the performance coefficient and heating efficiency of the heat pump.

Description

technical field [0001] The invention relates to a solution-type heat pump device and a cooling and heating method of a solar energy and air composite heat source with an energy storage function, and belongs to the technical field of design and manufacture of solar energy, refrigeration and air conditioning systems. Background technique [0002] Since the mid-1990s, my country has completely transformed from an energy exporter to a major energy importer, and the energy situation is very severe. With the wide application of large and medium-sized central air conditioners, air conditioners have gradually become a large energy consumer in buildings. Today, when energy problems are becoming more and more prominent, the application of renewable energy such as solar energy has become particularly important and urgent. The development of renewable energy such as solar energy and the future The introduction of solar renewable energy into the central air-conditioning system has become...
