Description

Technical Field

[0001] The utility model relates to the technical field of dehumidification heat pump units, in particular to a dual-mode dehumidification heat pump unit. Background Art

[0002] At present, the equipment used in indoor constant temperature swimming pools includes a three-in-one dehumidification heat pump, an air-energy swimming pool-specific heat pump, an air-energy hot water heat medium unit, and an air-energy hot water shower unit. This results in an indoor constant temperature swimming pool requiring four independent systems, with many pieces of equipment and a large installation site. It requires the supervision of multiple professionals, a complex system, high initial costs, high later operating costs, and a large outdoor installation area.

[0003] Existing technical problems:

[0004] 1. Existing indoor constant temperature swimming pool equipment is of many types, complicated to install, occupies a large installation area, has high initial investment cost and high subsequent maintenance cost.

[0005] 2. At present, the three-in-one dehumidification heat pump for swimming pools only provides auxiliary heating for swimming pool water. When the indoor cooling is in summer, the excess heat is discharged to the outside, and the air source that heats the pool water at a constant temperature discharges the cold air to the outside, resulting in energy waste.

[0006] 3. Traditional three-in-one dehumidification heat pumps require additional heat medium to maintain constant air temperature in winter, and the heat medium is provided by a separate hot water system.

[0007] 4. Indoor constant temperature swimming pools will have a public shower area, which requires a large amount of hot water. The traditional approach is to design a separate hot water system for showering, which is usually provided by an air source heat pump. Utility Model Content
