Abstract

The invention discloses a pressure reducing device and an air conditioner control method and a device. The pressure reducing device comprises a liquid storage tank capable of storing a refrigerant, a first pipe connected with air inlet pipes or air outlet pipes of the liquid storage tank and an outdoor side heat exchanger and provided with a first controllable switch, and a second pipe connected with air inlet pipes or air outlet pipes of the liquid storage tank and an air-liquid separator and provided with a second controllable switch, wherein the first controllable switch and the second controllable switch are connected with a controller, and can receive control signals of the controller and perform related actions. Under the condition that the system detects that the system pressure is too high, the controller can control the openness of the first controllable switch and / or the second controllable switch according to preset rules, so that the refrigerant in a system circulating pipe can be conveyed into the liquid storage tank through a first pipe and / or a second pipe, a system pressure value is reduced, and the normal work of the air conditioning system is guaranteed.

Description

Technical field [0001] The present invention relates to the technical field of electrical control, and more specifically, to a pressure reducing device, an air conditioning system, an air conditioning control method and device. Background technique [0002] During the operation of the air conditioner, the system pressure may be too high, and too high pressure will cause damage to the compressor and system components of the air conditioner. Therefore, in order to ensure the service life of each component of the air conditioner, it is necessary to solve the problem of excessive pressure in the air conditioner system. [0003] In the prior art, in order to avoid excessive pressure in the air conditioner system from damaging the compressor and various components, a high-pressure protection method is usually adopted. This method adds a high and low pressure switch or pressure sensor to the air conditioning system. When the system pressure is detected to exceed the set value, the system...
