Air conditioner system and air conditioner provided with same

Abstract

The invention discloses an air conditioner system and an air conditioner provided with the same. The air conditioner system comprises a compressor, an indoor heat exchanger, an outdoor heat exchanger, a reversing assembly, a first throttling element, a second throttling element, a gas-liquid separator and a liquid storage device. The compressor comprises a first air cylinder, a second air cylinder, an exhaust opening and an air return opening. The exhaust volume ratio of the second air cylinder to the first air cylinder is smaller than or equal to 0.1. The reversing assembly comprises a first valve opening, a second valve opening, a third valve opening and a fourth valve opening. When the air conditioner system conducts cooling, the first valve opening is communicated with the second valve opening, and the third valve opening is communicated with the fourth valve opening. When the air conditioner system conducts heating, the first valve opening is communicated with the third valve opening, the second valve opening is communicated with the fourth valve opening, and a gas outlet of the gas-liquid separator is communicated with the second air cylinder. According to the air conditioner system, the exhaust volume ratio of the second air cylinder to the first air cylinder is made to be smaller than or equal to 0.1, so that the performance of the air conditioner system can be effectively improved, and the air conditioner can reach the optimal state of energy efficiency easily.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular, to an air conditioning system and an air conditioner having the same. Background technique [0002] In the related technologies, for the rated cooling working condition, intermediate cooling working condition, rated heating working condition, intermediate heating working condition and low temperature heating working condition in the domestic APF standard, North American SEER working condition, HSPF working condition, European ERP working condition In addition, the air-conditioning system designed for APF working conditions and ultra-low temperature heating working conditions in Japan lacks the optimal design of the air-conditioning system, resulting in the ratio of the exhaust volume of the first cylinder of the designed compressor to the exhaust volume of the second cylinder is not high. Optimal range, which adversely affects the overall performance of the air con...
