Abstract

The invention discloses an injection enthalpy-increasing water-cooled air-cooled heat pump module unit, which comprises a refrigerant circulation module, a rectification module, a cold and heat source heat exchanger module, an injection enthalpy-increasing module, an economizer module and an indoor heat exchanger. This application highly integrates the traditional water-cooled refrigeration host and the cooling tower, and uses the air-cooled heat pump module unit as a template to add an air-cooled fin heat exchanger to the water-cooled unit to match the low-power screw compressor or scroll compressor. Created a brand-new model that integrates air-cooled heat pump unit and water cooler into one——injection enthalpy-increasing water-cooled air-cooled heat pump module unit, and uses air injection enthalpy-increasing and injection composite technology to greatly improve the mechanical efficiency of the heat pump , The double recovery of kinetic energy and heat energy in each physical link of the refrigerant circulation system can maximize the mechanical performance of the compressor unit, the overall energy efficiency of the unit is higher, the cost performance of the unit is improved, the economy of the unit is increased, and it is easy to popularize.

Description

technical field [0001] The invention relates to the field of heat exchangers, in particular to an air-cooled heat pump module unit cooled by ejected enthalpy water. Background technique [0002] The existing Fengshui integrated unit integrates the advantages of air cooling and water cooling. [0003] This type of feng shui integrated unit usually has the characteristics of small size and light weight, which is convenient for transportation, construction and maintenance. The wind-water integrated unit adopts the water cooling method, which avoids the problems of high condensing temperature and low cooling efficiency when the air-cooled heat pump unit is refrigerated; it avoids the lack of heating capacity of the chiller refrigeration unit, which is large in size and high in weight, which is inconvenient for transportation and installation. It avoids the problem of waste of indoor space caused by the need for indoor machine room; avoids the separation of the main unit and the...
