Problems solved by technology
[0004] However, when the refrigeration device realizes the operation of a single-stage compression system, a two-stage compression system, and a three-stage compression system, the system’s pipeline loss and throttling loss are large, resulting in a greatly reduced system heating capacity and energy efficiency.

Description
technical field [0001] The present application relates to the technical field of air conditioning, in particular to a system for supplementing air and increasing enthalpy and a control method thereof. Background technique [0002] The heating capacity of the air source heat pump decays rapidly as the outdoor ambient temperature drops and cannot meet the needs of users. The existing technology of double-stage or quasi-two-stage compression with air supplementation and enthalpy increase, including two-stage throttling intermediate incomplete cooling and one-stage throttling intermediate incomplete cooling cycle, can increase the low-temperature heating capacity and COP, and at the same time reduce the compressor Exhaust temperature helps somewhat. However, the existing technology has a limited range for improving capacity or energy efficiency, and also has a limited range for reducing the exhaust temperature of the high-pressure stage. [0003] For this reason, a kind of ref...
