The working principle of the double-stage heat recovery anti-condensation air conditioning unit for the swimming pool is as follows.
In summer, two stages of refrigeration and dehumidification are performed, the first stage is a third heat exchanger 5, a cold source of the third heat exchanger is chilled water of a central air-conditioning system, the second stage is a fourth heat exchanger 6 (namely an evaporator of the air-conditioning system), a built-in heat pump is in a refrigeration working condition, and the cold source is a low-temperature refrigerant (an environment-friendly refrigerant). After two-stage refrigeration dehumidification, the treated air can achieve a lower moisture content. The low-temperature dry air is subjected to heat dissipation of a condenser (a fifth heat exchanger 7 at the moment) and heat dissipation of an air supply fan 8 under the refrigeration working condition by a built-in heat pump, so that the purpose of supplying air by the processed air higher than the indoor dew point is achieved.
During refrigeration in summer, outdoor fresh air enters the first heat exchanger 1 from the fresh air inlet 10, meanwhile, indoor exhaust air enters from the exhaust air inlet 9, the outdoor fresh air and the indoor exhaust air are subjected to heat exchange (primary heat recovery) through the first heat exchanger 1, the fresh air after the heat exchange (after the heat exchange, the temperature of the fresh air is reduced, and the temperature of the exhaust air is increased) is mixed with indoor return air entering from the return air inlet 11, the mixed air is firstly subjected to primary refrigeration dehumidification through the third heat exchanger 5, then subjected to deep refrigeration and deep dehumidification through the fourth heat exchanger 6 to be changed into low-temperature dry air, and then heated through the fifth heat exchanger 7 (the process is secondary heat recovery under the working condition of summer), the heat of the compressor 2 is completely absorbed by the low-temperature dry air through the fifth heat exchanger 7 to be changed into high-temperature dry air which is higher than the dew-, the supply air outlet 12 feeds into the room of the pool at constant temperature. After heat exchange (temperature rise), the exhaust air flows through the compressor 2, the second heat exchanger 3 (at the moment, the second heat exchanger 3 does not work), the exhaust air fan 4 and the second exhaust air outlet 13 in sequence and is exhausted outdoors, and the exhaust air only carries away heat dissipation of the exhaust air fan 4 in the process and has no energy exchange with other unit components flowing through. The treatment process at the summer design conditions is shown in figure 2 on the psychrometric chart.
In winter, the third heat exchanger 5 adopts hot water of a central air conditioner to supply heat in winter, namely the heating coil, the heating coil is used for primary heating, the heat source is hot water of the central air conditioning system, the air conditioning system is changed into a heating working condition through a four-way reversing valve, an evaporator is changed into a condenser, the heating coil is used for secondary reheating, the heat source is a high-temperature refrigerant, and air heated by two stages meets the requirement of air supply of the air conditioner in winter. In the heating situation, the heat required by the evaporator (in this case the second heat exchanger 3) is all provided by the indoor exhaust air.
During heating in winter: outdoor new trend gets into from new trend entry 10, indoor air exhaust gets into from the entry 9 that airs exhaust, both carry out the heat exchange (one-level is retrieved) through first heat exchanger 1, new trend (new trend temperature improvement) after the heat exchange mixes with the indoor return air that gets into from return air entry 11, the air after the mixture is earlier through 5 heats of third heat exchanger, carry out the secondary heating through fourth heat exchanger 6 again, air conditioning system is through changing the four-way reversing valve, become the operating mode that heats, the air after handling becomes high temperature drying air, flow through fifth heat exchanger 7 again (the fifth heat exchanger 7 is out of work this moment, do not carry out the heat exchange), through air supply fan 8, supply-air outlet 12 sends to the indoor of constant temperature swimming pool. In winter, the four-way reversing valve is used, the condenser of the air conditioning system is the fourth heat exchanger 6, and the fifth heat exchanger 7 is not used in winter. The temperature of the exhausted air is reduced after heat exchange, the exhausted air sequentially flows through the compressor 2, the second heat exchanger 3 and the exhaust fan and is exhausted to the outside through the second exhaust outlet 13, the exhausted air is subjected to heat exchange with the second heat exchanger 3 after primary heat exchange in the process, the heat absorption of the evaporator is completely provided by the exhausted air under the heating condition of the built-in heat pump, the exhaust air temperature is further reduced, and the process is secondary heat recovery under the working condition in winter. The temperature of the exhausted air after primary heat exchange is still higher than the temperature of the outdoor air under the design working condition, the COP value of the heating working condition of the built-in heat pump is higher than that under the design working condition in the heat exchange process of the exhausted air and the evaporator of the built-in heat pump, and the heating can avoid frosting through calculation.
