Device for supplying heat to water resource heat pump by combination of solar energy and air energy

Abstract

The invention discloses a device for supplying heat to a water resource heat pump by combination of solar energy and air energy, belonging to the technical field of water resource heat pumps. The device comprises a solar heat gathering device, an air energy heat exchange device, the water resource heat pump and a hot water supply tank, wherein the water resource heat pump is in pipeline connection with the hot water supply tank; and the solar heat gathering device and the air energy heat exchange device are combined to supply heat to the water resource heat pump. The device has is simple in structure, is simple and reasonable and is convenient to install and use, can simultaneously supply heat through solar energy and air energy and can also selectively supply heat, air energy and solar energy complement each other, when solar energy is affected by cloudy and rainy weather, and heat is insufficiently supplied, air energy can also meet the condition for normal operation of a water resource heat pump unit, disadvantages are avoided, and the energy efficiency ratio of the water resource heat pump is obviously increased.

Description

Technical field [0001] The invention belongs to the technical field of water source heat pumps, and is specifically a device that combines solar energy and air energy to heat the water source heat pump. Background technique [0002] Solar energy is a renewable and environmentally friendly energy source with great development and application value. Solar energy collection technology is widely used in heating and hot water production, and has the advantages of energy saving, environmental protection, safety and reliability, and once and for all. However, solar energy generates heat by means of sunlight. In winter, the solar irradiance decreases and the heating efficiency decreases. At night, part of the heat will be dissipated through the water tank and pipes. If other auxiliary heat sources are not added to increase the water temperature, most of the time the heat The water cannot reach the temperature required by the user, and the hot water that is kept at a low temperature for a...

AI Technical Summary

Problems solved by technology

However, solar collectors and air source heat pumps have the defect of low efficiency in winter, and there is no complementarity. Moreover, the use of two independent heating equipment increases the investment cost of the project; there is also a heating method that combines solar energy and electric heating, which saves Investment, but power consumption increases
