Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/004972
Kind Code:
A1
Abstract:
A refrigeration cycle device (1) comprises a refrigerant circuit (11) and an adsorbent. The refrigerant circuit (11) has a compressor (31) that compresses the refrigerant and an expansion mechanism (32) that reduces the pressure of the refrigerant. The refrigerant circuit (11) constitutes a vapor compression refrigeration cycle in which the refrigerant circulates. The adsorbent adsorbs and desorbs the refrigerant circulating through a first unit. The refrigerant circuit (11) has a high pressure region and a low pressure region. The refrigeration cycle device (1) is operated on the basis of at least one of a first condition and a second condition. The first condition is that the pressure of the refrigerant in the high pressure region is not more than the critical pressure of the refrigerant, and that the temperature of the refrigerant in the high pressure region is greater than the critical temperature of the refrigerant. The second condition is that the pressure of the refrigerant in the low pressure region is lower than a saturation pressure corresponding to a vaporization temperature of the refrigerant when the adsorbent does not adsorb or desorb the refrigerant.
