Problems solved by technology

When running in winter, the heating demand cannot be met with the same capillary throttling parts, and the energy efficiency ratio will drop
Especially after the implementation of APF (Annual Performance Factor, annual energy efficiency consumption rate), the design of air conditioners should comprehensively consider the needs of cooling and heating, and the current throttling components of the system cannot meet the needs of APF
In addition, the design of the throttling parts of the current air conditioning system only considers the energy efficiency requirements of the system, but ignores the comfort requirements of rapid cooling and heating, which leads to the disadvantages of slow cooling in summer and slow heating in winter
[0003] It can be seen that the design of capillary throttling parts in current air conditioners not only cannot meet the needs of APF, but also cannot meet people's needs for rapid cooling and heating of air conditioners.

Abstract

The invention discloses an air conditioner, comprising an outdoor heat exchanger, a compressor, a four-way valve, an indoor heat exchanger, and a throttling device. Flow devices are sequentially connected by pipelines to form a circulation path; the throttling device includes throttling passages matching different flow rates, and one of the throttling passages is a rapid cooling and heating passage; the air conditioner also includes an indoor ambient temperature sensor and a The temperature sensor is electrically connected to the controller; the controller gates the corresponding throttling channel according to the temperature change detected by the indoor temperature sensor. The invention also discloses a control method of the air conditioner. The invention not only satisfies the requirement of APF, but also satisfies the requirement of fast cooling and heating.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner and a control method thereof that meet not only the requirements of APF but also the requirements of rapid cooling and heating. Background technique [0002] The current inverter air conditioner is designed according to the seasonal energy efficiency ratio. When operating in summer and transitional seasons, the capillary throttling and the system can be well matched. When running in winter, the same capillary throttling parts cannot meet the heating demand, and the energy efficiency ratio will drop. Especially after the implementation of APF (Annual Performance Factor, annual energy efficiency consumption rate), the design of air conditioners must take into account the needs of cooling and heating, and the current throttling components of the system cannot meet the needs of APF. In addition, the design of the throttling parts of the current air-conditioning sys...
