All-weather solar heat pump air-conditioning system

Abstract

The invention discloses an all-weather solar air-conditioning system. The all-weather solar air-conditioning system comprises a solar collector, a heat pump compressor and a user heat exchanger, wherein the solar collector consists of a body, an air blower, a coiled pipe heat exchanger, a spray system and a solar panel; an opening is formed in the upper part of the body; the air blower is mounted at the upper opening; an opening is formed in the side surface of the body; a guide plate is mounted at the opening of the side surface; the coiled pipe heat exchanger is mounted inside the body, and connected with the heat pump compressor through a pipeline; the solar panel is mounted on the outer part of the side surface of the body, and connected with the heat pump compressor through a pipeline; the spray system consists of a spray water pump mounted in a water collecting slot in the lower part of the body and a spray nozzle mounted in the opening of the side surface of the body, and the spray water pump is connected with the spray nozzle through a pipeline; the heat pump compressor is connected with the coiled pipe heat exchanger, the solar panel and the user heat exchanger through a pipeline.

Description

technical field [0001] The invention relates to the technical field of energy saving and energy utilization, in particular to an air-conditioning system applied to the air-conditioning and heating industry. Background technique [0002] In the southern part of my country, the temperature is low in winter, the humidity is high, the sunshine time is short, and people feel the temperature is low. In order to heat the building, methods of burning fossil energy such as coal, oil, and natural gas are often used to provide high-temperature air-conditioning water to the room through the boiler to increase the indoor temperature. While the heating efficiency is low, various environmental pollution problems are brought. With the development of heat pump technology, various heat pump heating types using different heat sources have been widely developed. Such as ground source heat pump, water source heat pump, air source heat pump and so on. Air source heat pumps have been widely pro...

AI Technical Summary

Problems solved by technology

However, due to the severe low temperature and high humidity in southern my country, air source heat pumps are often prone to frosting and defrosting, which reduces their work efficiency and affects the heating experience of users.

At present, the direct expansion solar heat pump water heaters in China have not been widely used due to unstable working conditions.

In particular, its efficiency drops sharply in the presence of little or no direct sunlight, which has affected its popularization.
