Integrated solar air source heat pump cooling and heating system

Abstract

The invention provides an integrated solar air source heat pump cooling and heating system and relates to the technical field of construction energy saving equipment. The integrated solar air source heat pump cooling and heating system comprises a solar energy system, an air source heat pump cooling and heating device, a water storage tank, a control cabinet, a solar vacuum breaker valve, a cooling and heating device vacuum breaker valve and the like. The gradient of preset positions of water channel pipes is 10-15 degrees. The water channel pipes are provided with the solar vacuum breaker valve and the cooling and heating device vacuum breaker valve correspondingly. The solar energy system, the air source heat pump cooling and heating device and the water storage tank form a closed loop through the water channel pipes. According to the integrated solar air source heat pump cooling and heating system provided by the embodiment of the invention, an antifreezing liquid circulation systemdoes not need to be arranged, a heat exchange device does not need to be mounted, and heat tapes do not need to be wound on the system pipes. The cooling and heating system provided by the inventioncan meet cooling and heating demands of users, the cost for replacement of antifreezing liquid is reduced, meanwhile, the heat tapes do not need to be driven by excessive electric energy, the purposeof energy saving is achieved, the cost is reduced, the service life is prolonged, and the cooling and heating system has good practicability.

Description

technical field [0001] The present application relates to the technical field of building energy-saving equipment, in particular to a cooling and heating system of a solar energy integrated air source heat pump. Background technique [0002] In recent years, due to the large-scale expansion of industrial production and the increasing energy consumption, many energy sources are in short supply. Now people are turning their attention to renewable energy in order to use renewable energy to alleviate the energy shortage problem. Based on the current background of the country's implementation of "coal to electricity", many energy-saving solutions and equipment have emerged as the times require. For example, an integrated system of solar water heater-air source heat pump unit utilizing solar energy resources and air energy resources. This system is a system in which solar water heaters and air source heat pump units work together, and the two assist each other. [0003] Accordin...
