Abstract

The invention discloses an air conditioner indoor heat exchanger, an air conditioner and a control method. The air conditioner indoor heat exchanger comprises an air pipe, a liquid pipe, a back-row heat exchanger, a front-row heat exchanger and a flow dividing pipeline. A first liquid inlet / outlet of the back-row heat exchanger is connected with a liquid pipe; a first valve is arranged at a first liquid inlet / outlet of the back-row heat exchanger; a liquid inlet / outlet of the front-row heat exchanger is connected with a second liquid inlet / outlet of the rear-row heat exchanger; the front-row heat exchanger is located on the windward side of the rear-row One end of the shunting pipeline is connected with the liquid pipe, and the other end of the shunting pipeline is connected with a second liquid inlet / outlet of the back-row heat exchanger; a second valve is arranged on the shunting pipeline; by adjusting the opening degrees of the first valve and the second valve, the quantity of refrigerants entering the back-row heat exchanger and the flow dividing pipeline is adjusted, so that the temperature of the refrigerants entering the front-row heat exchanger can be adjusted, the evaporation temperature of the front-row heat exchanger is adjusted, the heat exchange effect is improved, and the problem that the heat exchange effect is poor is solved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an indoor heat exchanger for an air conditioner, an air conditioner and a control method. Background technique [0002] In low-temperature environments, such as communication base stations, bars, etc., although the external temperature is low, the air conditioner still needs to be operated for cooling. [0003] Existing air conditioners operate refrigerating in a low temperature environment. Due to the low evaporating temperature and condensing temperature, and no adjustment device, the heat exchange effect becomes poor, the cooling effect is relatively poor, and the cooling demand cannot be met. SUMMARY OF THE INVENTION [0004] The invention provides an indoor heat exchanger for an air conditioner, which solves the problem of poor heat exchange effect. [0005] In order to achieve the above-mentioned technical purpose, the present invention adopts the fo...
