[0025] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0026] Reference Figure 1 As shown, the household fresh air constant temperature and humidity system according to an embodiment of this utility model includes a room and a cold and heat source device. The room is equipped with underfloor heating 100, a radiant air conditioner 200, and a fresh air dehumidifier unit 300. The cold and heat source device includes a cold water tank 400, a cold and hot water tank 500, and a temperature regulating device. A first circulating water path 410 is provided between the cold water tank 400 and the fresh air dehumidifier unit 300, and a second circulating water path 510 is provided between the cold and hot water tank 500 and the underfloor heating 100. A third circulating water path 520 is provided between the hot and cold water tank 500 and the radiant air conditioner 200; the temperature regulating device includes a first water tank 600, a second water tank 700, and a control structure 800 for cooling the first water tank 600 and for cooling or heating the second water tank 700. A fourth circulating water path 610 is provided between the first water tank 600 and the cold water tank 400, and a fifth circulating water path 710 is provided between the second water tank 700 and the hot and cold water tank 500.

[0027] By installing underfloor heating 100, radiant air conditioning 200, and a fresh air dehumidifier 300 in the room, when it is necessary to adjust the room temperature, humidity, and underfloor heating 100 temperature, it is only necessary to control the temperature of the first water tank 600 and the second water tank 700 through the control structure 800. In turn, the first water tank 600 changes the temperature of the cold water supplied to the cold water tank 400, thereby controlling the temperature of the cold water in the cold water tank 400. Thus, the fresh air dehumidifier 300 can filter the fresh air and control the room humidity by exchanging heat between the cold water and the fresh air. Furthermore, the second water tank 700 changes the temperature of the cold or hot water supplied to the hot and cold water tank 500. Thus, the radiant air conditioning 200 can control the room temperature according to the hot or cold water supplied by the hot and cold water tank 500, and the underfloor heating 100 can control its temperature according to the hot or cold water supplied by the hot and cold water tank 500, thereby achieving the control of the room temperature, humidity, and underfloor heating 100 temperature.

[0028] During operation, based on the required room temperature, humidity, and underfloor heating temperature, the water in the first water tank 600 and the water in the cold water tank 400 circulate through the fourth circulating water path 610. The control structure 800 controls the temperature of the water in the first water tank 600, thereby adjusting the temperature of the cold water in the cold water tank 400. When the temperature of the cold water in the cold water tank 400 reaches the specified temperature, the control structure 800 stops controlling and stops the water circulation. The cold water tank 400 delivers the cold water to the fresh air dehumidifier unit 300 through the first circulating water path 410. The fresh air dehumidifier unit 300 filters the fresh air entering the room and controls the humidity. When the humidity changes, the control structure 800 continues to control and circulate the water to ensure that the temperature of the cold water in the cold water tank 400 reaches the specified temperature.

[0029] The water in the second water tank 700 and the water in the hot and cold water tanks 500 circulate through the fifth circulating water path 710. The control structure 800 controls the temperature of the water in the second water tank 700, thereby regulating the temperature of the cold or hot water in the hot and cold water tanks 500. When the temperature of the cold or hot water in the hot and cold water tanks 500 reaches the specified temperature, the control structure 800 stops controlling and stops the water circulation. The hot and cold water tanks 500 then deliver the cold or hot water to the underfloor heating 100 and the radiant air conditioning 200 through the second circulating water path 510, thereby controlling the temperature of the underfloor heating 100 and the temperature of the radiant air conditioning 200 in the room, so that the temperature of the underfloor heating 100 and the room temperature reach the specified temperature. When the temperature of the cold or hot water in the hot and cold water tanks 500 changes, the control structure 800 continues to control and circulate the water to ensure that the temperature of the cold or hot water in the hot and cold water tanks 500 reaches the specified temperature.

[0030] In some embodiments of this utility model, such as Figure 2As shown, the control structure 800 includes a compressor 810, a first evaporator 820, a first expansion valve 830, a first condenser 840, and a four-way valve 850. The air inlet and outlet of the compressor 810 are both connected to the four-way valve 850. The two ends of the first evaporator 820 are respectively connected to one end of the four-way valve 850 and one end of the first expansion valve 830. The two ends of the first condenser 840 are respectively connected to the other end of the first expansion valve 830 and the four-way valve 850. The first evaporator 820 is used to heat or cool the water in the second water tank 700.

[0031] Specifically, the four-way valve 850 has a first port 851, a second port 852, a third port 853 and a fourth port 854. The outlet of the compressor 810 is connected to the first port 851. The two ends of the first evaporator 820 are respectively connected to the third port 853 and one end of the first expansion valve 830. The two ends of the first condenser 840 are respectively connected to the other end of the first expansion valve 830 and the second port 852. The outlet of the compressor 810 is connected to the fourth port 854.

[0032] like Figure 2 As shown, when it is necessary to heat the water in the second water tank 700, the first port 851 is connected to the third port 853, and the second port 852 is connected to the fourth port 854. The high-temperature and high-pressure gas in the compressor 810 enters the first evaporator 820 through the first port 851 and the third port 853. The gas in the first evaporator 820 is at a high temperature, so the first evaporator 820 can heat the water in the second water tank 700. After the gas discharged from the first evaporator 820 passes through the first expansion valve 830 and the first condenser 840 to reduce pressure and temperature, the low-temperature and low-pressure gas returns to the compressor 810 through the second port 852 and the fourth port 854, and the cycle continues.

[0033] like Figure 3 As shown, when it is necessary to cool the water in the second water tank 700, the first port 851 is connected to the second port 852, and the third port 853 is connected to the fourth port 854. The high-temperature and high-pressure gas in the compressor 810 enters the first condenser 840 through the first port 851 and the second port 852. After the high-temperature and high-pressure gas is cooled and depressurized by the first condenser 840 and the first expansion valve 830, it enters the evaporator. The gas in the first evaporator 820 is low-temperature, so the first evaporator 820 can cool the water in the second water tank 700. The low-temperature and low-pressure gas discharged from the first evaporator 820 returns to the compressor 810 through the third port 853 and the fourth port 854, and the cycle continues.

[0034] Specifically, the water in the second water tank 700 can circulate into the first evaporator 820, so that the gas in the first evaporator 820 can exchange heat with the water in the second water tank 700.

[0035] In a further embodiment of this utility model, such as Figure 4 As shown, the control structure 800 also includes a second evaporator 860, a second expansion valve 870, a second condenser 880, and a surface cooler 890. The inlet of the second evaporator 860 is connected to the outlet through a first pipe 861. A first valve 862 is provided on the first pipe 861. The two ends of the second expansion valve 870 are connected to the outlet of the second evaporator 860 and the inlet of the second condenser 880, respectively. The outlet of the second condenser 880 is connected to the pipe between the first condenser 840 and the four-way valve 850. The surface cooler 890 exchanges heat with the second condenser 880 and is used to cool the water in the first water tank 600. A second valve 811 is provided on the pipe between the outlet of the compressor 810 and the four-way valve 850.

[0036] The control structure 800 adopts the above-described structure, which allows a single compressor 810 to control the water temperature of the first water tank 600 and the water temperature of the second water tank 700.

[0037] like Figure 4 As shown, when the first water tank 600 needs to be cooled, the first valve 862 is opened, the second valve 811 is closed, and the second port 852 is connected to the fourth port 854. The high-temperature and high-pressure gas in the compressor 810 enters the second evaporator 860. After the high-temperature and high-pressure gas passes through the second evaporator 860 and the second expansion valve 870 to reduce pressure and temperature, it enters the second condenser 880. The gas in the second condenser 880 is at a low temperature, so the second condenser 880 can exchange heat with the surface cooler 890. Thus, the surface cooler 890 can cool the water in the first water tank 600. The gas coming out of the second condenser 880 returns to the compressor 810 through the second port 852 and the fourth port 854, realizing a cycle.

[0038] When the first water tank 600 is not required to be cooled, the first valve 862 is closed, the second valve 811 is opened, and the first evaporator 820 is used for cooling or heating.

[0039] In a further embodiment of this utility model, such as Figure 4 As shown, the control structure 800 includes a fan assembly 801. The first condenser 840 is located below the second evaporator 860. The fan assembly 801 is located to the left of the second evaporator 860 and to the left of the first condenser 840. By providing the fan assembly 801, the heat dissipation of the second evaporator 860 and the first condenser 840 is accelerated.

[0040] In a further embodiment of this utility model, such as Figure 4As shown, the first pipe 861 and the pipe between the outlet of the compressor 810 and the first port 851 of the four-way valve 850 are all equipped with one-way valves 863 to prevent high-temperature and high-pressure gas from flowing back to the compressor 810.

[0041] In a further embodiment of this utility model, such as Figure 4 As shown, a first filter 821 is installed in the pipe between the first evaporator 820 and the third port 853 of the four-way valve 850, and a second filter 864 is connected in the pipe between the second evaporator 860 and the second expansion valve 870 to filter impurities in the gas and improve the life of the compressor 810.

[0042] In some embodiments of this utility model, such as Figure 1 As shown, it also includes a fan coil unit 802 installed in the room, a third circulating water circuit 520 including an inlet pipe 521 and an outlet pipe 522, a hot and cold water tank 500 connected to a radiant air conditioner 200 through the inlet pipe 521 and the outlet pipe 522, the inlet of the fan coil unit 802 connected to the inlet pipe 521 through the second pipe 8021, and the outlet of the fan coil unit 802 connected to the outlet pipe 522 through the third pipe 8022.

[0043] In addition to the radiant heating and cooling air conditioner 200, a fan coil unit 802 is also installed to better control the temperature in the room.

[0044] During operation, cold or hot water is simultaneously supplied to the radiant air conditioner 200 and the fan coil unit 802. The liquid in the fan coil unit 802 exchanges heat with the air in the room to control the room temperature.

[0045] In a further embodiment of this utility model, such as Figure 1 As shown, both the second pipe 8021 and the third pipe 8022 are equipped with a third valve 8023, which controls the heat exchange and whether the fan coil unit 802 is used.

[0046] In a further embodiment of this utility model, such as Figure 1 As shown, multiple fan coil units 802 are configured to improve room temperature control.

[0047] In a further embodiment of this utility model, such as Figure 1 As shown, a pump 523 is installed in the water inlet pipe 521. The connection between the second pipe 8021 and the water inlet pipe 521 is located downstream of the pump 523, so that the fan coil unit 802 and the radiant air conditioner 200 share a single pump 523, thereby reducing costs.
