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 a blast pipe type CO2 air conditioning heat pump unit which comprises a first gas cooler, a second gas cooler, a liquid four-way reversing valve, a gas-liquid separator, a heat regenerator, a compressor, an ejector, a gas four-way reversing valve, an evaporator and an air valve. According to the invention, through reasonable arrangement of a system flow, the mode conversion of refrigeration, heating, defrosting and dehumidification is realized through controlling an electromagnetic valve of the unit, so that the unit has comprehensive functions and meets daily needs; the air valve and the second gas cooler are combined to replace an electric heater in a traditional system, so that the energy consumption of electric heating is reduced, and the system performance is improved; and CO2 is adopted to serve as a working medium, is inert gas, and free from toxin and stimulation.

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...
