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

Abstract

A solar-air source energy storage type solution thermal pumping device is a method and a device for realizing the method, and the method is solar-air source energy storage type solution thermal pumping for refrigeration and heat-production on the basis of refrigerating with cool water in summer and absorbing heat from air with solution in winter and by means of taking advantages of solar energy. The device comprises a refrigerant circulation loop, a solution circulation loop and an air circulation loop, and is composed of main members of a cold and hot water unit, a cooling tower, a solar heat collector, a solution regenerator, a concentrated solution storage device, a dilute solution storage device and the like. In summer, the device can realize water-cooled water chilling unit function, absorb heat by evaporation in the cooling tower with cooling water, cooling agent of the water chilling unit prepares cold water, in winter, solution is used to exchange heat with air in the cooling tower, heat is absorbed for the unit to prepare hot water, thereby radically resolving inescapable frost produced when existing air source heat pump operates to produce heat in winter, and increasing performance coefficient and heat supply efficiency.

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...
