When the power is used in peak, the power is in tension, and when the power is used in off-peak, the power is not fully utilized, so that the power demand of the peak is transferred, the power supply is balanced, and the effective utilization of the power is improved, thereby becoming a concern.
Ice storage is a mode of making water into ice, and the latent heat of phase change of the ice is utilized for storing cold energy. The ice storage air conditioner utilizes night low-valley load power to make ice and store the ice in the ice storage device, and the ice melting in the daytime releases the stored cold energy so as to reduce the power consumption load of the air conditioner in the peak period of the power grid.
The existing ice cold storage air conditioner makes ice through the ice coil, the freezing mode of the ice coil is hard ice, and in the normal ice making process, a refrigerant is injected into the ice coil, so that the ice forms an ice column outside the ice coil, and a non-freezing safety gap exists between the ice column and the ice column. When the temperature of the refrigerant is too low or the refrigerating capacity is increased, the phenomenon of icing easily occurs, and the safety gap between the ice column and the ice column formed outside the ice coil is frozen into ice. The volume of water in the sealed safety gap is amplified by 1.1 times after being frozen into ice, so that a huge extrusion force is generated, the extrusion force is conducted back to the ice coil along the original ice column, and strong extrusion stress is caused on the ice coil, so that the ice coil is damaged, the ice coil can deform and leak, the service life of the ice coil is shortened, and the probability of failure is increased.
