Problems solved by technology

[0003] In fact, the air conditioning system of heat pump unit + fan coil unit + fresh air unit still has the following weaknesses: the cooling (heating) system and the fresh air system are two systems, and the control system is also two independent systems, which cannot be coordinated and unified. The user's operation is difficult, maintenance is difficult, and energy saving cannot be concentrated

Abstract

An airing style central air conditioning hot pump set is achieved by: connecting compressor exhaust with inlet of four-way reversing valve, its outlet connected with refrigerant intake of an airing condenser; connecting the refrigerant outlet of the condenser with a throttle with its exit connected with refrigerant intake of an distiller via a one-way valve; and connecting refrigerant outlet of the distiller with the compressor inlet via the four-way valve to form a loop. The apparatus can be used to cool in summer and to heat in winter at regions where no adequate water exists. It has a fresh air intake unit, and omits water-cooling unit and air-circulating unit so as to prevent from infection of diseases.

Description

Technical field: [0001] The invention relates to the technical field of air-conditioning regulation systems, in particular to an air-cooled central air-conditioning heat pump unit with fresh air. Background technique: [0002] Fresh air is a crucial performance parameter for central air-conditioning. At present, the more popular air-conditioning systems with fresh air generally include heat pump unit + fan coil unit + fresh air unit; heat pump unit + hybrid air handler (fresh air and return air are in the air handler Medium mix); three types of heat pump unit + fresh air air handler. In recent days, it has been found that many deadly viruses such as SARS in buildings are mainly transmitted through the return air system of the air conditioner. Therefore, the method of mixed air treatment has been questioned by humans; the fresh air treatment can effectively prevent it because there is no return air Viruses spread, but due to the high operating costs, this system cannot be po...
