Abstract

A high temperature self-adapting air conditioner comprises a refrigerating circle which is composed by a compressor, a condenser, main capillary, an evaporator. The refrigerating circle is parallel connected by a subsidiary throttle sidecut which is composed by a filter, an unloading valve and subsidiary capillary. Due to the subsidiary throttle sidecut, upon the side condenser's pressure exceeds the safety limit, the unloading valve opens and the subsidiary sidecut got through; then the flux index of the capillary will be increased, refrigerant flux will be increased; then lower down the pressure of the condenser; then the compressor will be protected for a continuous running.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a high-temperature self-adaptive split-type air conditioner, which belongs to the improvement technology of the existing split-type air conditioner. Background technique [0002] Split air conditioners currently on the market are divided into three types according to the type of climate they can adapt to: T1, T2, and T3. These three types of air conditioners adapt to different ambient temperatures, the T1 type is suitable for temperate climates, and the T3 type is suitable for high temperature climates. T1-type air conditioners are not suitable for use in T3 high-temperature areas, because when T1-type split air conditioners operate in very harsh high-temperature climates, the condensation pressure on the outdoor side is very high, the exhaust temperature increases rapidly, and the compressor is overloaded. It will lead to frequent protection...
