Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0029] The air duct machine in this application performs the refrigeration cycle of the air duct machine by using a compressor, an expansion valve, and a heat exchanger. The refrigeration cycle consists of a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to air that has been conditioned and heat exchanged.

[0030] The compressor compresses refrigerant gas in a high-temperature and high-pressure state and discharges the ...

Abstract

According to the air conditioner, a first refrigerant opening is connected with an outlet, and a third refrigerant opening is connected with an inlet; one end of the outdoor heat exchanger is connected with the second refrigerant port, and a branch where the outdoor heat exchanger is located is connected with a first throttling device in series; a first connecting port of the heat recovery heat exchanger is connected with a second refrigerant port, and a branch where the heat recovery heat exchanger is located is connected with a second throttling device in series; one end of the indoor heat exchanger is connected with the other end of the outdoor heat exchanger and the second connector, and the other end of the indoor heat exchanger is connected with the fourth refrigerant port; one end of the heat exchanger for heating is connected with the third connector, and the other end of the heat exchanger for heating is connected with the fourth connector; the liquid pump is connected in series to a circulation loop formed by the heat recovery heat exchanger and the heat exchanger for heating. According to the air conditioner, the condensation heat dissipating capacity of the refrigerant can be effectively recycled to heat the indoor air, so that constant-temperature dehumidification and temperature rise dehumidification of the air conditioner are achieved, and then the air conditioner can better meet the requirements of users.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner. Background technique [0002] In the related technology, in the constant temperature dehumidification mode of the air conditioner, the high-temperature and high-pressure refrigerant discharged from the compressor will first pass through the condenser and then enter the heating part and dehumidification part of the indoor unit. The constant temperature dehumidification of the air conditioner is achieved by balancing the cooling capacity of the internal refrigerant. However, in the above process, due to the temperature difference between the refrigerant and the air and the long flow of the hairpin tube of the condenser, there will always be a part of natural heat dissipation during the process of the refrigerant flowing through the condenser, resulting in a decrease in the heating capacity of the refrigerant entering the heating part. This makes it dif...
