A control method of ice cold storage air conditioner based on spray heat exchange

Abstract

The invention discloses a control method of an ice cold storage air conditioner based on spray heat exchange. Obtain the real-time air supply temperature T11 and the real-time water temperature T21 of the storage bin; when T21>T2, the control device outputs a prompt for water drainage and ice replacement; when T21≤T2 and T1‑T0≤T11≤T1+T0, the control device controls the pressure pump. The speed remains unchanged; when T21≤T2 and T11>T1+T0, the control device controls to increase the speed of the pressurized water pump; when T21≤T2 and T11<T1‑T0, the control device controls to reduce the speed of the pressurized water pump; In the control method provided by the present invention, the control device obtains the real-time water temperature of the storage bin and adjusts the working state of the pressurized water pump according to the comparison result of the real-time water temperature and the set temperature of the storage bin, so as to realize the adjustment of the working state of the ice storage air conditioner, and fully utilize the storage bin. The cooling capacity of the melted water in the refrigerator improves the energy utilization rate of the ice storage air conditioner.

Description

technical field [0001] The invention relates to the technical field of ice cold storage air conditioners, in particular to a control method of an ice cold storage air conditioner based on spray heat exchange. Background technique [0002] The existing ice-storage air conditioner uses low-cost electricity to make ice-storage to store the cold energy during the downtime of the power grid at night. During the peak electricity consumption period during the day, the ice melts into water, absorbs heat and provides cooling together with the refrigeration 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 realized by direct contact between the outside air and ice, 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 melt...

AI Technical Summary

Problems solved by technology

[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
