Example Embodiment

[0021] The present invention will be further described in detail below with reference to the drawings and specific embodiments, but it is not intended to limit the present invention.

[0022] Such as figure 1 with figure 2 As shown, the embodiment of the present invention provides an air conditioning system, including a compressor 1, an evaporator 2, and a condenser 3. The outlet pipeline of the compressor 1 has a first connection position and a second connection position. When the outlet pipeline of the compressor 1 is at the first connection position, the outlet pipeline of the compressor 1 is in communication with the inlet pipeline of the evaporator 2. When the outlet pipe of the compressor 1 is in the second connection position, the outlet pipe of the compressor communicates with the inlet pipe of the condenser 3; the outlet pipe of the condenser 3 communicates with the evaporator 2, and the outlet pipe of the evaporator 2 Connect with compressor 1.

Abstract

The invention discloses an air-conditioning system and a defrosting method thereof. The air-conditioning system comprises a compressor, an evaporator and a condenser. An outlet pipeline of the compressor is provided with a first connecting position and a second connecting position. When the outlet pipeline of the compressor is located at the first connecting position, the outlet pipe of the compressor communicates with an inlet pipeline of the evaporator. When the outlet pipeline of the compressor is located at the second connecting position, the outlet pipe of the compressor communicates with an inlet pipeline of the condenser. An outlet pipeline of the condenser communicates with the evaporator. An outlet pipeline of the evaporator communicates with the compressor. According to the technical scheme, when the evaporator needs to be defrosted, high-temperature and high-pressure gas exhausted out of the compressor can be adjusted to be directly led into the evaporator for defrosting, the defrosting time of the evaporator is shortened, the defrosting effect of the evaporator is improved, the low-temperature refrigerating capacity is increased, and the problem that defrosting of the evaporator is incomplete or the defrosting cycle is long under the low-temperature working condition is solved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning system and a defrosting method thereof. Background technique [0002] In special conditions such as computer rooms, the indoor ambient temperature is relatively high. In order to ensure that the indoor temperature is lower than a certain value, the air conditioner is required to operate normally even when the outdoor ambient temperature is very low, even when the outdoor ambient temperature is low. Cooling operation is also required at -15°C. When the outdoor ambient temperature is low, the condensation temperature of the outdoor condenser is very low, and the evaporation temperature of the evaporator is also very low. At the inlet of the evaporator, the temperature is often below 0°C. However, due to the high indoor ambient temperature, there is an obvious intersection of cold and heat on the surface of the evaporator, and because the inlet tempera...
