Dual fresh air and dual exhaust air multifunctional swimming pool heat pump air conditioner unit

Abstract

The invention relates to a dual fresh air and dual exhaust air multifunctional swimming pool heat pump air conditioner unit. The heat pump air conditioner unit is sequentially provided with a primarymixing segment, a cooling dehumidifying segment, an air return fan segment, a secondary mixing segment, a main heating segment, an auxiliary heating segment, and an air supply machine segment in the direction of air treatment. The primary mixing segment and the secondary mixing segment each comprise a fresh air adjusting valve, an air exhaust adjusting valve and an air return adjusting valve. Eachair return adjusting valve is connected with the corresponding fresh air adjusting valve and the corresponding air exhaust adjusting valve, the cooling dehumidifying segment is an evaporator of a heat pump system, the main heating segment is a condenser of the heat pump system, a complete heat pump system is formed through the evaporator, an inner condenser, an outer condenser and a compression mechanism, the unit is provided with two fresh air openings, and according to outdoor air hot wet state, primary and secondary fresh air amounts can be introduced, the unit has multiple different workmodes, energy in exhaust air and fresh air can be sufficiently used, the air treatment process is determined, and the advantages of saving more energy, being efficient and accurate in running, and more flexible in control are achieved.

Description

technical field [0001] The invention relates to an air conditioning unit, in particular to a multifunctional swimming pool heat pump air conditioning unit. Background technique [0002] The indoor air temperature of the swimming pool is about 26-30°C, the air is humid, the relative humidity is about 70-90%, the people are relatively dense, and the fresh air volume per capita is large. Therefore, the dehumidification load of air conditioning in swimming pool buildings is large, and the demand for fresh air is large. In view of the above characteristics, the air conditioning unit used in the swimming pool is also relatively special, not only to provide cooling and heating for the room, but also to take into account the dehumidification function. At present, heat pump air handling units are widely used, also known as three-in-one units. This type of unit generally includes an evaporation section, a mixing section, and a reheating section along the direction of the air supply a...

Problems solved by technology

The disadvantage of this type of air conditioning unit is that in summer and some transitional seasons, part of the return air after cooling and dehumidification treatment needs to be discharged, which wastes cooling capacity. The greater the fresh air volume, the more cooling capacity is wasted; on the other hand, the The air conditioning unit sends the fresh air into the room without cooling and dehumidifying it. Due to the high temperature and high humidity of the outdoor air in summer, only when the return air is treated until the temperature and relative humidity are both very low can the air supply be satisfied after mixing, resulting in the failure of the unit.
