Air conditioner and its energy-saving control method

Abstract

The invention discloses an air conditioner and an energy-saving control method thereof, comprising: judging whether to enter a sleep shutdown mode or a timing shutdown mode; if yes, entering the energy-saving control mode when the distance from the set shutdown time is the first time a; Including: adjusting the opening and closing state of the compressor so that the compressor is in the shutdown state when the distance from the set shutdown time is the second time b; judging whether the temperature difference t is greater than e1; if the temperature difference t>e1, then start the compressor; if If the temperature difference t≤e1, the compressor will remain in the shutdown state until the temperature difference t>e1 to start the compressor; the distance from the set shutdown time is within the range of [third time c, 0], the compressor will remain or switch to the shutdown state until the air conditioner is completely The machine is turned off, or the compressor is kept or switched to the running state, and finally stops until the air conditioner is turned off. Therefore, rationally adjust the operation logic to maximize the comfort and energy saving of the air conditioner, and protect various loads related to start and stop to prolong the service life.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner and an energy-saving control method thereof. Background technique [0002] At present, when the sleep shutdown or timer shutdown function is set for air-conditioning products, there is no special control for the air conditioner before the set time reaches the shutdown, so that the energy-saving effect of the air conditioner cannot be maximized. For example, the compressor is still running when it is turned off, the air conditioner still has a lot of cooling capacity or heat that has not been fully released, resulting in energy waste, and the compressor and other loads have the phenomenon that they are turned off immediately when the shutdown time comes, which affects the service life. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present inve...

Problems solved by technology

[0002] At present, when the air-conditioning products set the function of sleep shutdown or timer shutdown, there is no special control for the air conditioner before the set time reaches the shutdown, so that the energy-saving effect of the air conditioner cannot be maximized.

For example, the compressor is still running when it is turned off, and the air conditioner still has a lot of cooling capacity or heat that has not been fully released, resulting in energy waste. There is a phenomenon that the load such as the compressor has just been turned on and then turned off immediately due to the shutdown time, which affects the service life.
