Title:
FRESH AIR CONDITIONING SYSTEM AND HEAT RECOVERY METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/110898
Kind Code:
A1
Abstract:
A fresh air conditioning system and a heat recovery method thereof. The fresh air conditioning system comprises a first heat exchange device, the first heat exchange device being provided in a fresh air channel, and further comprises a water collecting member (600) and a recovery heat exchanger (205), the water collecting member (600) being located at the bottom of the first heat exchange device to collect condensed water from the first heat exchange device, the recovery heat exchanger (205) being communicated with the water collecting member (600) and communicated with a working medium of the first heat exchange device, and the working medium exchanging heat with the condensed water in the recovery heat exchanger (205) in advance. Fresh air undergoes heat exchange by means of the first heat exchange device; during cooling and dehumidification, condensed water is formed by means of condensation in the first heat exchange device in an air cooling process, and the condensed water is introduced into the recovery heat exchanger (205) by means of the water collecting member (600) to secondarily recover and reuse energy of the condensed water and exchange heat with a refrigerant or the working medium in an air conditioner, such that the supercooling degree of the recovery heat exchanger is increased, and the energy loss of the air conditioner is reduced.
