Title:
BI-DIRECTIONAL FIRST-TYPE SINGLE WORKING MEDIUM COMBINED CYCLE
Document Type and Number:
WIPO Patent Application WO/2021/143550
Kind Code:
A1
Abstract:
The present invention relates to the technical field of thermodynamics, refrigeration and heat pumps. Provided is a bi-directional first-type single working medium combined cycle. The bi-directional first-type single working medium combined cycle refers to a closed process consisting of nine processes carried out separately or jointly with a working medium consisting of M1 kg and M2 kg of working media, i.e., an endothermic vaporization process of M1 kg working medium (12), an endothermic process of (M1 + M2) kg working medium (23), a pressure increasing process of (M1 + M2) kg working medium (34), an endothermic process of (M1 + M2) kg working medium (45), a pressure reduction process of (M1 + M2) kg working medium (56), an exothermic process of (M1 + M2) kg working medium (67), a pressure reduction process of M2 kg working medium (72), an exothermic condensation process of M1 kg working medium (78), and a pressure reduction process of M1 kg working medium (81).
