Embodiment 1

[0024] According to an embodiment of the present invention, an embodiment of a method for starting an air conditioner compressor is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0025] figure 1 It is a method for starting an air conditioner compressor according to an embodiment of the present invention. Optionally, the air conditioner compressor includes three cylinders, such as figure 1 As shown, the method may include the following steps:

[0026] In step S12, after the air conditioner enters the heating mode, it is detected whether the air conditioner is in the anti-cold wind protection state.

[0027] In the above step S12, the controller of the air conditio...

Embodiment 2

[0067] The embodiment of the present invention can also provide a starting device for an air conditioner compressor, the compressor of the air conditioner includes three cylinders, such as figure 2 As shown, the device may include: a first detection unit 200 , a first control unit 210 and a second control unit 220 .

[0068] Wherein, the first detection unit 200 is configured to detect whether the air conditioner is in a protection state against cold wind after the air conditioner enters the heating mode. The first control unit 210 is configured to control at least two of the three cylinders of the compressor to operate at a first frequency when the air conditioner is in a protection state against cold wind. The second control unit 220 is configured to control the three cylinders of the compressor to operate at a second frequency after at least two cylinders operate at the first frequency for a first predetermined period of time, wherein the second frequency is greater than t...

Abstract

The invention discloses a method and a device for starting an air conditioner compressor. Wherein, the method includes: after the air conditioner enters the heating mode, detecting whether the air conditioner is in the anti-cold wind protection state; frequency operation; after at least two cylinders operate at the first frequency for a first predetermined period of time, three cylinders of the compressor are controlled to operate at a second frequency, wherein the second frequency is greater than the first frequency. The invention solves the problem in the prior art that during the anti-cold wind protection period after the air conditioner starts the heating mode, all the cylinders in the three-cylinder compressor of the air conditioner work at the operating frequency of the actual working condition at the same time, resulting in an excessive load on the air conditioner compressor technical problem.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a method and device for starting an air conditioner compressor. Background technique [0002] In areas with cold winters (such as the north), a large amount of low-grade energy such as coal or natural gas is often burned for heating, which aggravates air pollution and energy consumption. Considering energy and environmental issues, air source heat pumps can be used for heating. Since the temperature in the north is very low in winter, the heating capacity and energy efficiency of ordinary heat pumps are relatively low. Based on the above reasons, variable capacity compressors can be used to solve the problem of low heating capacity and energy efficiency of ordinary heat pumps, that is, variable capacity compressors can adjust the volume ratio of the compressor through different working loads, so as to achieve different heating capacities At present, variable capacity compressors ...
