The working principle of the invention is as follows:
an ice making process: the ice water conveying pump 6 is started and the valve is opened, ice water in the water tank 21 is conveyed to the ice water distribution pipe 113, a small amount of water is sprayed into the ice sheet groove 111 through the water spray nozzle 114 (the time is short), the ice water conveying pump 6 is closed, the compressor 3 is started to start the ice making mode, after water at the bottom in the ice sheet groove 111 is frozen, the ice water conveying pump 6 is started again, the ice water is sprayed into the ice sheet groove 111 through the water spray nozzle 114 until the ice water is filled in the ice sheet groove 111, and then the ice water conveying pump 6 is closed. At this point, after a period of time (about 50min), the ice-making process phase ends. In the ice making process, cooling water enters from a water inlet connecting pipe 22 of a water tank 21, continuously exchanges heat with a refrigeration working medium in a condensation heat exchange pipe 24 through the condensation heat exchange pipe 24 to heat up, then flows out from a water outlet connecting pipe 23 at the tail part, and enters a water storage tank for storage and standby (the temperature can be further increased to 40-50 ℃ for heating, bathing and other domestic water). The refrigeration working medium completes four thermal processes of heat absorption evaporation, steam compression, steam condensation and throttling pressure reduction in the ice maker 11, the compressor 3, the condenser 2 and the throttling valve 4 to complete reverse Carnot cycle, and heat is transferred from a low-temperature heat source to a high-temperature heat source to complete the ice making process.
The process of deicing and conveying flake ice: the four-way change-over valve 5 is changed by the control system to change the refrigeration mode to the heating mode, the ice maker 11 (evaporator) is changed into a condenser, the condenser 2 is changed into an evaporator, ice close to the four walls begins to melt due to the heating of the evaporation refrigeration walls of the ice maker 11, after the ice near the wall surfaces completely melts, the whole weight of the ice is pressed on the spring bottom plate 117 of the ice maker 11, the spring bottom plate 117 begins to reverse under the action of gravity, the flake ice in the flake ice groove 111 falls into the ice receiving groove of the flake ice storage and transportation cabinet 14 by gravity, after the whole flake ice falls into the flake ice storage and transportation cabinet 14, the hatch 13 at the lower part of the left end socket of the ice making tank 1 is opened, the flake ice storage and transportation cabinet 14 full of flake ice is pulled out of the ice making tank 1, the empty flake ice storage and transportation cabinet 14 is sent into the ice making tank 1, the hatch 13 is closed, and the next ice making cycle is carried out.
The working process of the ice storage air conditioning system is as follows: during the night valley electricity period, the sheet ice machine works circularly for many times to store the sheet ice in the ice storage cabinet B, when the air conditioner is in the peak in the daytime, the sheet ice in the ice storage cabinet B sequentially enters the ice crusher C, the sheet ice is crushed into ice powder, the ice powder enters the stirring and mixing tank D and is stirred and mixed with the air-conditioning circulating water, the ice powder is quickly cooled, the air-conditioning circulating water enters the ice water storage tank E after the temperature of the air-conditioning circulating water is reduced to be close to zero, the circulating pump F is started, the low-temperature air-conditioning circulating water is sent to each air-conditioning user H, the circulating water releases cold energy, and the circulating water enters the mixing and mixing tank D after the temperature is increased, so that the air-conditioning process is continuously completed circularly.
