Control method of ice storage air conditioner based on spraying heat exchange

Abstract

The invention discloses a control method of an ice storage air conditioner based on spraying heat exchange. The control method comprises the steps that a control device obtains the set air supply control precision T0, the set air supply temperature T1 and the set temperature T2 of an ice storage box; the control device obtains the real-time air supply temperature T11 and the real-time water temperature T21 of the ice storage box; when T21 is greater than T2, the control device outputs a water draining and ice changing prompt; when T21 is less than or equal to T2 and T11 is greater than or equal to T1 - T0 and less than or equal to T1 + T0, the control device controls the rotating speed of a pressurizing water pump to keep unchanged; when T21 is less than or equal to T2 and T11 is greater than T1 + T0, the control device controls to increase the rotating speed of the pressurizing water pump; and when T21 is less than or equal to T2 and T11 is less than T1 - T0, the control device controls to reduce the rotating speed of the pressurizing water pump. According to the control method, the control device obtains the real-time water temperature of the ice storage box and adjusts the working state of the pressurizing water pump according to a comparison result of the real-time water temperature and the set temperature of the ice storage box, so that the working state of the ice storage air conditioner is adjusted, the cooling capacity of molten water in the ice storage box is fully utilized, and the energy utilization rate of the ice storage air conditioner is increased.

Description

technical field [0001] The invention relates to the technical field of ice storage air conditioners, in particular to a control method for ice storage air conditioners based on spray heat exchange. Background technique [0002] The existing ice-storage air conditioner uses low-cost electric ice storage to store cold energy during the low-valley time of the power grid at night. When it is in the peak period of electricity consumption during the day, the ice melts into water, absorbs heat and supplies cooling together with the refrigerating unit; Some ice storage air conditioners have problems such as heavy weight, inconvenient movement, and poor user experience. [0003] In addition, the heat exchange process of some existing ice-storage air conditioners is achieved through direct contact with ice from the outside air, and the air output by the ice-storage air conditioner may carry crushed ice and water droplets, which reduces the user experience; and When the ice melts into...

[0002] The existing ice-storage air conditioner uses low-cost electric ice storage to store cold energy during the low-valley time of the power grid at night. When it is in the peak period of electricity consumption during the day, the ice melts into water, absorbs heat and supplies cooling together with the refrigerating unit; Some ice storage air conditioners have problems such as heavy weight, inconvenient movement, and poor user experience

[0003] In addition, the heat exchange process of some existing ice-storage air conditioners is achieved through direct contact with ice from the outside air, and the air output by the ice-storage air conditioner may carry crushed ice and water droplets, which reduces the user experience; and When the ice melts into water, the melted water is generally directly discharged out of the ice storage air conditioner, which cannot be reused, which leads to the problem of high energy consumption of the existing ice storage air conditioner
