Abstract:The water heater of an air source heat pump has the disadvantages of high
exhaust temperature and weak heating performance in a cold area. The quasi
two-stage compression cycle technology can effectively improve its operation
characteristics in the cold area. In this paper, a rotor compressor with a
medium pressure air supply is used to develop the water heater with R410A
as the circulating working fluid. The system's heating performance under low
temperature environments is experimentally st… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
