Problems solved by technology

On the one hand, such an auxiliary heating device complicates the system and increases the equipment cost; on the other hand, it increases the energy consumption of the system during operation and reduces the heating efficiency of the system.
In addition, the working pressure of the traditional ducted air-conditioning heat pump unit is low, the energy-saving effect of using the ejector is not obvious, a large amount of expansion work is wasted, and the system performance is low

Abstract

The invention discloses an air duct type CO2 air conditioner heat pump unit, which comprises a first gas cooler, a second gas cooler, a liquid four-way reversing valve, a gas-liquid separator, a regenerator, a compressor, an injector, a gas Four-way reversing valve, evaporator and air valve; the present invention realizes the mode conversion of cooling, heating, defrosting and dehumidification by controlling the solenoid valve of the unit by rationally setting the system flow. The unit has comprehensive functions and meets the daily needs; the present invention uses the combination of the air valve and the second gas cooler to replace the electric heater in the traditional system, reduces the energy consumption of electric heating, and improves the performance of the system; the present invention CO2 is used as the working fluid of the system. CO2 is an inert gas, non-toxic and non-irritating.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning heat pumps, in particular to an air duct type CO 2 Air conditioning heat pump unit. Background technique [0002] The air duct unit connects an outdoor unit and an indoor unit with copper pipes, and the cold air (warm air) generated by the indoor unit is led out of the air supply pipe to each room, and then sent back to the indoor unit through the return air pipe, and cooled. (heating) and mixing part of the fresh air before sending it out. It is a central air conditioner with a new air system. The energy-saving effect is obvious. The air duct air-conditioning heat pump unit is a direct cooling system with a high evaporation temperature. Under certain other conditions, increasing the evaporation temperature can improve the efficiency and energy efficiency ratio of the unit. The air duct type unit air conditioner unit has a large capacity, which can meet the cooling (heating) requirement...
