air conditioner

Abstract

The present invention provides an air conditioner, comprising a compressor connected by pipelines, an outdoor heat exchanger, a throttling device and an indoor heat exchanger, the inlet side of the throttling device is a high-pressure side, the outlet side is a low-pressure side, and It includes a refrigerant regulating flow path connected in parallel with the throttling device. The refrigerant regulating flow path is provided with a refrigerant storage and electromagnetic on-off valves located on both sides of the refrigerant storage. By controlling the on-off state of the electromagnetic on-off valve, the control The communication status of the refrigerant accumulator with the high-pressure side pipeline and the low-pressure side pipeline. In the air conditioner provided by the present invention, a refrigerant regulating flow path connected in parallel with the throttling device is added between the high pressure side and the low pressure side, the refrigerant storage is used to store the refrigerant, and the on-off state of the electromagnetic on-off valve is controlled to control Which side of the pipeline is connected to the refrigerant storage, so as to adjust the amount of refrigerant stored in the refrigerant storage, and then realize the adjustment effect on the refrigerant amount in the refrigeration and heating cycle pipeline, and meet the complex use conditions.

Description

Technical field [0001] The invention relates to the technical field of air conditioners, and more particularly relates to an air conditioner. technical background [0002] For existing air-conditioning devices, such as split air-conditioners, window machines, mobile air-conditioners and other small refrigeration systems, the refrigerant is filled in the factory, and the filling amount is fixed. Generally, this charging amount is the best amount debugged in the laboratory under a certain standard working condition before production. However, the refrigerant with a fixed charging amount can't meet the complicated use conditions. [0003] Specifically, when users use it, with the change of indoor and outdoor temperature and humidity, the amount of refrigerant is not optimal, more or less, which will cause problems such as decreased cooling and heating effect, increased power, and even water blowing. Frequency conversion air conditioner can change the frequency and the opening of ele...

This charging amount is generally the best amount debugged in the laboratory under a certain standard working condition before production, but the refrigerant with a fixed charging amount cannot meet complex use conditions

[0003] Specifically, when the user is using it, with the change of indoor and outdoor temperature and humidity, the amount of refrigerant is not optimal, more or less, which will cause the cooling and heating effect to decrease, the power to increase, and even blow water and other problems; Inverter air conditioners can change the frequency and the opening of the electronic expansion valve, but the amount of refrigerant cannot be adjusted; the split air conditioner is installed on site. After many years of use, the refrigerant leaks, and the amount of refrigerant in the air conditioner is obviously insufficient, resulting in cooling and heating. Decreased effect, need to maintain and increase refrigerant, bring troubles to users
