Integral air conditioner and control method thereof

Abstract

The invention discloses an integral air conditioner and a control method thereof. The integral air conditioner comprises a chassis, an electric control box, a compressor, a throttling device, an indoor heat exchanger, an outdoor heat exchanger and a heat dissipation device, wherein the heat dissipation device comprises a first refrigerant flow path and a second refrigerant flow path which are connected between the outdoor heat exchanger and the throttling device in parallel, and further comprises a radiator and a flow control part; the radiator is connected on the first refrigerant flow path in series; and the flow control part can control flow of the first refrigerant flow path and the second refrigerant flow path. According to the integral air conditioner provided by the invention, effective heat dissipation can be carried out on a part to be subjected to heat dissipation; when the temperature of a refrigerant flowing through the heat dissipation device is too low, the flow of the refrigerant flowing through the radiator can be decreased; and during refrigeration operation, the refrigerant flowing into the radiator is not throttled, and the refrigerant in the radiator is prevented from being too cold, so that condensation on the part to be subjected to heat dissipation is avoided, and the operation reliability of the system is improved.

Description

technical field [0001] The invention relates to the field of refrigeration and heating equipment, in particular to an integral air conditioner and a control method thereof. Background technique [0002] The electric control module of the frequency conversion machine has the problem of high heat generation. If the temperature is too high, it will have a great impact on the life of the electronic control components. At present, there are two main cooling technologies for the electric control box in the industry. One is air cooling, which is to use The wind field of the fan drives the electric control box to dissipate heat; the other is refrigerant cooling, that is, the refrigerant with a lower temperature in the system is introduced into the electric control box, and the cooling capacity of the refrigerant is used to dissipate heat from the electric control box. Among them, the first air-cooling method is noisy and has a lot of dust in the box, while the second refrigerant coo...
