Double fresh air, double exhaust multifunctional swimming pool heat pump air conditioning unit

Abstract

The invention relates to a swimming pool multifunctional heat pump air conditioner unit with double fresh air and double exhaust air. The heat pump air conditioner unit is sequentially provided with a primary mixing section, a cooling and dehumidification section, a return fan section, a secondary mixing section, and a main heating section along the direction of air treatment. section, auxiliary heating section, blower section; the primary mixing section and the secondary mixing section both include a fresh air regulating valve, an exhaust air regulating valve and a return air regulating valve, and the return air regulating valve is connected to the fresh air regulating valve and the exhaust air regulating valve respectively; cooling and dehumidification The heating section is the evaporator of the heat pump system; the main heating section is the condenser of the heat pump system; the evaporator, inner condenser, outer condenser, and compressor form a complete heat pump system. The unit is equipped with two fresh air outlets, which can determine the amount of primary and secondary fresh air introduced according to the heat and humidity state of the outdoor air; the unit can be set in a variety of different working modes to make full use of the energy in the exhaust air and fresh air to determine The air treatment process has the characteristics of more energy saving, more efficient and accurate operation, and more flexible control.

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. Lower operating COP
