Description

Technical Field

[0001] The utility model relates to the field of air conditioners, and particularly relates to an isothermal dehumidification triple supply system. Background Art

[0002] An air source triple supply system can provide air conditioning, floor heating, and hot water for a living environment. In the cooling mode, the air source heat pump absorbs the heat in the room and discharges it to the outside through the condenser, while releasing the cold air in the room to the room through the evaporator, thereby achieving indoor cooling and being able to provide domestic hot water at the same time. In the heating mode, the heat pump absorbs the heat energy outside and discharges it to the room through the evaporator, while discharging the cold air in the room to the outside through the condenser, thereby achieving indoor heating and being able to provide domestic hot water at the same time. In the hot water mode, the system absorbs and converts the heat energy in the air, converting low-grade heat energy into high-grade hot water.

One end of the compressor is connected to the second condenser, and the other end of the second condenser is connected to the first condenser and the evaporator. The other ends of the first condenser and the evaporator are connected to the compressor through the four-way valve.

The triple heat supply heat pump main unit 1 is respectively connected to the domestic water tank 5 and the hydraulic center 2 through water pipes. The hydraulic center 2 is connected to the dehumidification refrigerator 4 through a water pipe, and includes a ground hot air blower 3.

[0028] Since cold air sinks, the temperature on the ground is usually lower than that on the roof. Sending hot air on the ground can avoid the influence of condensate water generated due to too low ground temperature on the safety of users walking.

[0029] The dehumidification refrigerator 4 includes a refrigeration coil and a reheating coil. The refrigeration coil is connected to the hydraulic center 2 through a water pipe.

[0033] As Figure 2 shown, the triple heat supply heat pump main unit 1 includes a compressor 15, a four-way valve 16, an evaporator 17, a first condenser 18, and a second condenser 19. One end of the compressor 15 is connected to the second condenser 19, and the other end of the second condenser 19 is connected to the first condenser 18 and the evaporator 17. The other ends of the first condenser 18 and the evaporator 17 are connected to the compressor 15 through the four-way valve 16. An evaporation heat exchange coil is covered outside the evaporator 17, and a condensation heat exchange coil is covered outside the second condenser 19.

[0034] The evaporative heat exchange coil is connected to the hydraulic center 2 through a water pipe, and the condensation heat exchange coil is connected to the domestic water tank 5 through a water pipe.

[0036] The two water pipes of the evaporative heat exchange coil are respectively communicated with the first water tank 25 and the second water tank 26, and the first water tank 25 and the second water tank 26 are connected to the refrigeration coil in the dehumidification refrigerator 4 through a water pipe.

[0037] The usage method of this embodiment:

[0038] In the dehumidification season, the triple heat pump main unit 1 operates, and the second condenser 19 in the triple heat pump main unit 1 works to recover the condensed heat and produce domestic hot water for free. Then, the condensation heat exchange coil provides hot water to the domestic water tank 5, the domestic water tank 5 provides hot water to the domestic water terminal, and the heat exchange coil arranged in the domestic water tank provides hot water to the reheating coil. The triple heat pump main unit 1 provides cold water to the hydraulic center 2, and the hydraulic center 2 provides cold water to the refrigeration coil in the dehumidification refrigerator 4. The refrigeration coil in the dehumidification refrigerator 4 cools and dehumidifies the humid air.

At the same time, since cold air will gather on the ground surface, turning on the ground hot air blower 3 can avoid the condensed water generated due to too low ground temperature from affecting the safety of users walking.

[0039] In the refrigeration season, the triple heat pump main unit 1 operates, and the second condenser 19 in the triple heat pump main unit 1 works to recover the condensed heat and produce domestic hot water for free. Then, the condensation heat exchange coil provides hot water to the domestic water tank 5, the domestic water tank 5 provides hot water to the domestic water terminal, and the water circulation of the heat exchange coil arranged in the domestic water tank is closed, so that the heat exchange coil no longer provides hot water to the reheating coil. The triple heat pump main unit 1 provides cold water to the hydraulic center 2, and the hydraulic center 2 provides cold water to the refrigeration coil in the dehumidification refrigerator 4. The refrigeration coil in the dehumidification refrigerator 4 cools and dehumidifies the humid air, and the dried and low-temperature air after dehumidification is blown out through the blower. At the same time, since cold air will gather on the ground surface, turning on the ground hot air blower 3 can avoid the condensed water generated due to too low ground temperature from affecting the safety of users walking.
