An air source heat pump based on the concept of energy saving and environmental protection

Abstract

The invention discloses an air source heat pump based on the concept of energy saving and environmental protection, which comprises an outer case, an inner case, an evaporator, a gas-liquid separator, an air compressor, a liquid storage tank, a condenser, a dry filter, an expansion valve, a first Circulating water pump, first solenoid valve, second circulating water pump, second solenoid valve, third solenoid valve, stepping motor and electric push rod, the inside of the outer case is fixed with an evaporator by screws, and one end of the evaporator A gas-liquid separator is connected through a pipeline, and the other end of the evaporator is connected with an expansion valve through a pipeline, the other end of the gas-liquid separator is connected with an air compressor through a pipeline, and the other end of the air compressor is connected through a pipeline There is a condenser, and the top of the condenser is provided with a first water delivery pipe. The invention has a sunshade and heat preservation structure, which can prevent summer sun exposure, improve summer cooling effect, and simultaneously prevent the problem of frosting of the evaporator in winter.

Description

technical field [0001] The invention relates to the technical field of air source heat pumps, in particular to an air source heat pump based on the concept of energy saving and environmental protection. Background technique [0002] With the maturity and development of air source heat pump technology, air source heat pump hot water heating has gradually entered the homes of ordinary people with its outstanding energy-saving and environmental protection performance. Air source heat pumps convert low-grade heat from air or underground into high-grade heat. The device itself only needs to consume a small amount of electricity, does not need to burn fuel, does not produce waste gas and other pollutants, and is very environmentally friendly. [0003] Air source heat pumps are generally composed of four major components: a compressor, an evaporator, a condenser, and a throttle valve. The working system basically revolves around these major components. The main component that consu...
