The invention relates to the technical field of air conditioning, in particular to a method for controlling heat storage of an air conditioner. The present invention aims to solve the problems of low control precision and poor user experience in the existing preheating scheme in advance. For this purpose, the heat storage control method of the present invention includes: obtaining the preset start-up time of the air conditioner; modifying the preset start-up time based on the time correction parameter; determining the heat storage time of the air conditioner based on the outdoor ambient temperature; Preset the start-up time and heat storage time, and calculate the heat storage start time of the air conditioner; when the heat storage start time is reached, determine the heat storage frequency of the compressor based on the outdoor ambient temperature; control the compressor to run at the heat storage frequency; Control the outdoor fan to run at the same time, before or after the machine starts running. Through the above control method, the heat storage control method of the present invention can increase the life of the compressor, greatly improve the control accuracy of the heat storage process of the air conditioner, and improve user experience.

The invention provides a method for coating the inner wall of an atomic gas chamber for slowing down the relaxation of atomic spins. The method firstly uses rubidium atom vapor to fill the atomic gas chamber, and then passes through a hydride solid gas release agent (such as titanium hydride, calcium hydride, etc.) Release hydrogen gas with a pressure of 10Torr to 100Torr into the atomic gas chamber, and keep it at a temperature of 50°C to 150°C for tens to hundreds of hours. A layer of rubidium hydride film will be attached to the inner wall of the atomic gas chamber, and finally the residual hydrogen in the gas chamber will be evacuated , to end the coating process, the present invention uses a solid gas release agent to generate hydrogen in the above coating process, compared with the traditional use of high-pressure hydrogen cylinders as a hydrogen source, it improves the process safety of rubidium hydride coating on the inner wall of the atomic gas, and the hydrogenation After rubidium coating, the residual hydrogen in the gas chamber is evacuated, which is beneficial to improve the stability of the performance of the atomic gas chamber compared with directly sealing the hydrogen in the gas chamber.

The invention relates to the technical field of air conditioning, in particular to a method for controlling heat storage of an air conditioner. The present invention aims to solve the problems of low control precision and poor user experience in the existing preheating scheme in advance. The thermal storage control method of the present invention includes: when the predicted time point is reached, based on the pre-established scoring system, calculating the probability score of turning on the heating mode at the next predicted start-up time; when the probability score is greater than the set threshold, the time-based correction parameter Correct the predicted start-up time; calculate the heat storage start time based on the corrected predicted start-up time and the preset heat storage time; when the heat storage start time is reached, determine the heat storage frequency of the compressor based on the outdoor ambient temperature; control the compressor to The heat storage frequency operates and controls the operation of the outdoor fan. Through the above control method, the heat storage control method of the present invention can increase the life of the compressor, greatly improve the control accuracy of the heat storage process of the air conditioner, and improve user experience.

A battery is assembled from cells arranged along an axis. The cells have end faces parallel to the line and first and second sides perpendicular to the faces. The first side of a first cell contacts the second side of a second cell. A sealed piping circuit includes a first heat exchanger in contact with, and spanning, the end faces and a second heat exchanger in fluid communication with the first heat exchanger for heat transfer between the heat exchangers.
