Problems solved by technology

The technical disadvantage of using temperature to control the chassis heater is that during the defrosting period of the air conditioner, the temperature of the air near the heat exchanger fluctuates greatly, which will affect the accuracy of starting the heating device and cause the chassis to Defrost is not clean, the heater is turned on or off for no reason, waste of electric energy and other adverse effects

Abstract

The invention discloses a deicing control method of an outdoor unit chassis of an air conditioner. The deicing control method of the outdoor unit chassis of the air conditioner comprises the step thata first pressure sensor arranged on the side wall surface of the outdoor unit chassis, a second pressure sensor arranged near a water outlet of the outdoor unit chassis and an electric heating modulearranged at the outdoor unit chassis control the starting of the electric heating module by using the first pressure sensor and control the closing of the electric heating module by using the secondpressure sensor. The pressure sensors are used for controlling the deicing operation of the chassis, so that the control is more accurate, the air-conditioning performance can be improved, and the reliability of the system operation is ensured; and compared with a traditional temperature control method, the deicing effect and the energy-saving effect are better.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a deicing control method for the chassis of an outdoor unit of an air conditioner. Background technique [0002] When the air conditioner is heating at low temperature, there will be frosting on the condenser. At this time, the system will enter the defrosting state, so there will be condensed water flowing along the condenser to the chassis of the outdoor unit, and then drained from the drain hole of the chassis of the outdoor unit. . At this time, the outdoor ambient temperature is low, which may cause the condensed water on the chassis to condense into ice, and in extreme ice and snow weather, some ice and snow may also be blown into the chassis of the outdoor unit of the air conditioner by the wind. The occurrence of the above conditions will lead to the following consequences : (1) The drain hole is blocked by ice, causing the condensed water to continue to ...
