Defrosting-free air cooling and water cooling all-in-one machine air source heat pump

Abstract

The invention relates to a defrosting-free air cooling and water cooling all-in-one machine air source heat pump. The defrosting-free air cooling and water cooling all-in-one machine air source heat pump is composed of an air heat exchange part and a heat transmission tail end part which are connected through a pipeline, and a circulating medium in the connecting pipeline is a refrigerant or a secondary refrigerant. The air heat exchange part is mainly composed of an exhaust fan, a spraying head, a fin heat exchanger, grid-shaped padding, a liquid storage tank, an automatic antifreezing liquid guiding and discharging pipe, a retaining liquid surface control switch and a spraying water pump. According to the heat transmission tail end part, when a low-power compressor system with a four-way valve is selected, the structure of the defrosting-free air cooling and water cooling all-in-one machine air source heat pump is the same with that of a common air source heat pump; and when a large-power compressor system without a four-way valve is selected, the structure of the defrosting-free air cooling and water cooling all-in-one machine air source heat pump is the same with the structure of a water source heat pump and a water cooling unit. According to the defrosting-free air cooling and water cooling all-in-one machine air source heat pump, defrosting is avoided during operation in winter, the refrigerating coefficient of operation in summer is the same with that of the water cooling unit, the high-power compressor system can be applied to the air source heat pump unit, and the high-power water cooling unit can be applied to the field of heating in winter.

Description

technical field [0001] The invention relates to a frost-free air-cooled and water-cooled integrated air source heat pump, which converts heat energy in the air into water, and is mainly used in the fields of heating in winter and central air conditioning in summer. Background technique [0002] At present, during the operation of the existing air source heat pump units in winter, when the surface of the air heat exchanger meets the frosting conditions, frost will form, and defrosting is required to ensure the normal operation of the air source heat pump. There are two obvious flaws: [0003] One is that defrosting needs to pay heat energy, which is far greater than the heat energy obtained from the frosting phase transition, that is, the defrosting process is a process that consumes extra heat, and the higher the humidity, the more heat energy paid for defrosting. In theory, the greater the humidity, the greater the latent heat that the heat exchanger absorbs into the phase...
