Surrounding type refrigeration device in water cold storage

Abstract

The invention provides a surrounding type refrigeration device in water cold storage and belongs to the field of energy storage. The surrounding type refrigeration device comprises a first cold storage tank, the bottom end of the first cold storage tank is communicated with a water discharge pipe, an electromagnetic valve is arranged on the water discharge pipe which is inclined, the other end of the water discharge pipe is communicated with a second cold storage tank, the lower end of the second cold storage tank is communicated with a water return pipe, the other end of the water return pipe is communicated with the first cold storage tank, a water pump is arranged on the water return pipe, a temperature sensor and a water level sensor are arranged on the inner wall of the cold storage tank, the temperature sensor controls the water pump, the water level sensor controls the electromagnetic valve, a spiral pipe is arranged on the outer wall of the second cold storage tank, one end of the spiral pipe is wound from the upper end of the second cold storage tank to the lower end of the second cold storage tank and then spirally wound from the lower end to the upper end of the second cold storage tank, one end of the spiral pipe is communicated with a heat pipe, the other end of the spiral pipe is communicated with a cold pipe, air pumps are arranged on both the cold pipe and the heat pipe, and cold water is sprayed to the temperature sensor when the electromagnetic valve is turned on. The refrigeration device is high in refrigeration efficiency and cold energy utilization rate.

Description

technical field [0001] The invention belongs to the field of energy storage, and relates to a surround-type refrigeration device in water cold storage. Background technique [0002] Water storage technology uses the difference in peak and valley electricity prices to store cooling capacity in water during low electricity price periods, and use stored low-temperature frozen water to provide cooling for air conditioners during peak hours of electricity consumption during the day. When the use time of the air conditioner is synchronized with the use time of the non-air conditioner and the peak and trough of the power grid, the power consumption of the air conditioner in the peak time of the power grid can be transferred to the trough of the power grid to save electricity. [0003] Natural stratification is temperature stratification. Temperature stratified water storage uses the physical property of water with different densities at different temperatures, and relies on the den...
