Embodiment 1

[0047] A combined fresh air-capillary network air conditioning system in this embodiment includes an outdoor unit 100 , a fresh air unit 300 and a radiation temperature adjustment unit 200 . Wherein, the outdoor unit 100 includes a compressor 110, an outdoor main pipe 413 and a four-way valve 140, the exhaust port 111 and the suction port 112 of the compressor 110 are respectively connected with the four-way valve 140, and the exhaust port 111 of the compressor 110 is The gas pipe 411 is connected with the D port of the four-way valve 140; the compressor 110 compresses the working medium into a high-temperature and high-pressure gaseous state through mechanical work, and the high-temperature and high-pressure gaseous working medium is transported to the exhaust pipe 411 through the exhaust port 111 for use The suction port 112 of the compressor 110 communicates with the S port of the four-way valve 140 through the outdoor return pipe 412; the low-temperature and low-pressure ga...

Embodiment 2

[0061] Such as Figure 4 As shown, the system of this embodiment is the same as that of Embodiment 1. This embodiment is a refrigeration process of a combined fresh air-capillary network air conditioning system of the present invention. When the external environment is in summer or the room needs to be at a lower temperature, The system starts the cooling process. The refrigeration process of the system is:

[0062] Such as Figure 1~3 As shown, the compressor 110 compresses the working fluid to generate a high-temperature and high-pressure gaseous working medium, and the high-temperature and high-pressure gaseous working medium is transported to the exhaust pipe 411, and then the gaseous working medium is divided into two paths, and one path reaches the four-way valve 140 The D port of the other way flows into the bypass pipe 433.

[0063] A. The path where the high-temperature and high-pressure gaseous working medium in the exhaust pipe 411 reaches the port of the four-wa...

Embodiment 3

[0070] Such as Figure 5 As shown, the system of this embodiment is the same as that of Embodiment 1. This embodiment is a heating process of a combined fresh air-capillary network air conditioning system of the present invention. When the external environment is in winter or the room needs to be at a higher temperature , the system starts the heating process. The heating process of the system is:

[0071] Such as Figure 1~3 As shown, the compressor 110 compresses the working fluid to generate a high-temperature and high-pressure gaseous working medium, and the high-temperature and high-pressure gaseous working medium is transported to the exhaust pipe 411, and then the gaseous working medium is divided into two paths, and one path reaches the four-way valve 140 The D port of the other way flows into the bypass pipe 433.

[0072]A. The path where the high-temperature and high-pressure gaseous working medium in the exhaust pipe 411 reaches port C of the four-way valve 140 i...

Abstract

The invention discloses a fresh air-capillary network air combined adjustment system and a fresh air temperature adjustment method in winter and summer thereof, and belongs to the field of air conditioning equipment. The fresh air-capillary network air combined adjustment system comprises an outdoor unit, a fresh air unit and a radiation temperature adjusting unit; the outdoor unit comprises a compressor, an outdoor main pipe and a four-way valve; the radiation temperature adjustment unit comprises a temperature adjustment heat exchanger, an adjustment valve and a capillary network; and the fresh air unit comprises a refrigeration heat exchanger and a reheating heat exchanger. The outdoor unit provides corresponding working medium for the fresh air unit and the radiation temperature adjusting unit through the work of the compressor, so that the fresh air unit and the radiation temperature adjusting unit can work independently and stably, the cost for simultaneous working of the fresh air unit and the radiation temperature adjusting unit is reduced, and the space required for installing equipment is reduced. In addition, the fresh air temperature adjustment method in winter and summer of the fresh air-capillary network air combined adjustment system reasonably distributes the flow rate of a working medium discharged from an exhaust port of the compressor, so that the fresh air temperature treatment effect is capable of being improved and the stable operation of the whole system is facilitated.

Description

technical field [0001] The invention relates to the field of air conditioning equipment, and more specifically, relates to a combined fresh air-capillary network air conditioning system and a method for adjusting the temperature of fresh air in winter and summer. Background technique [0002] With the continuous improvement of people's living standards and the continuous advancement of technology, users have higher and higher requirements for the indoor environment; the traditional forced convection heat exchange air conditioner uses the form of indoor air circulation and convection heat transfer to change the indoor temperature and humidity. It is easy to cause discomfort to indoor users. In the late 1980s, the invention of the capillary network planar radiation system by German DonadHerbst attracted widespread attention. In the following decades, this invisible air-conditioning system was successively applied to many high-end commercial buildings, government buildings, ba...
