Description

Technical Field

[0001] The utility model belongs to the technical field of heating, refrigeration and dehumidification equipment, in particular to a hot fluorine dehumidification and defrosting system. Background Art

[0002] Dehumidification means the air conditioner is in dehumidification mode, with the indoor unit's fan running very slowly. This allows moisture in the air to condense into liquid, achieving the desired dehumidification effect. Generally, when the air conditioner reaches the set temperature in dehumidification mode, the outdoor unit stops operating to prevent further evaporation of dew on the condenser.

[0003] For example, a heating, cooling and dehumidification system with Chinese patent application number CN202322332680.4 "belongs to the technical field of heating, cooling and dehumidification equipment; the utility model is composed of a Copeland digital compressor, a two-way liquid reservoir, a two-way expansion valve, a four-way reversing valve, a three-way valve, a cooling, heating and dehumidifying air blower (indoor unit), etc. The cooling and heating humidity can be automatically controlled, and the temperature and humidity in the cold storage can be adjusted by controlling the four-way reversing valve and the two-position three-way valve." In an environment with high dehumidification requirements, the dehumidification effect of this structure still cannot meet the specific requirements, so further improvements are being made to this point.

DETAILED DESCRIPTION

[0012] The technical solution of the present invention will be further specifically described below with reference to the embodiments and the accompanying drawings.

[0013] Example: A hot fluorine dehumidification and defrosting system, such as Figure 1As shown, it includes a first outdoor unit 1, which is characterized in that: a second outdoor unit 2 is provided on one side of the first outdoor unit 1, a first compressor 11 is correspondingly provided on one side of the first outdoor unit 1, and a second compressor 12 is correspondingly provided on one side of the second outdoor unit 2. A four-way reversing valve 9 is connected to the pipeline between the first outdoor unit 1 and the first compressor 11, and one end of the four-way reversing valve 9 is connected to a gas-liquid separator 10. The other end of the gas-liquid separator 10 is interconnected with the first compressor 11, and one end of the four-way reversing valve 9 is connected to the first compressor 11.
