Snow pack refrigerating machine and defrosting method thereof

Abstract

The invention discloses a snow pack refrigerating machine and a defrosting method thereof, and belongs to the energy supply field. The snow pack refrigerating machine comprises a return air chamber, afresh air chamber and a refrigerating chamber, and further comprises a heat recovery rotor with two ends respectively located in the return air chamber and the fresh air chamber, wherein the heat recovery rotor is used for mixing air in the return air chamber with air in the fresh air chamber, the return air chamber is provided with a return air inlet and a return air outlet, a first air feedingmachine is arranged between the heat recovery rotor and the return air outlet, the fresh air chamber communicates with the refrigerating chamber, the fresh air chamber is provided with a fresh air inlet, the refrigerating chamber is provided with a refrigerator and an air feeding port, a second air feeding machine is arranged between the heat recovery rotor and the refrigerator, the fresh air inlet, the heat recovery rotor, the second air feeding machine, the refrigerator and the air feeding port are sequentially arranged, and the first air feeding machine and the second air feeding machine are used for driving the air to flow through the heat recovery rotor. The defrosting method of the snow pack refrigerating machine includes an air return step, a fresh air intaking step, a cold and hotair mixing step, an air exhausting step and an air feeding step. The snow pack refrigerating machine and the control method thereof can reduce refrigerating energy consumption, and achieve dehumidification and defrosting of the refrigerating process.

Description

technical field [0001] The invention relates to the field of energy supply, in particular to a snow field refrigerator and a defrosting method thereof. Background technique [0002] At present, in order to enable people to experience the low temperature environment under unnatural climate conditions, such as skiing, indoor snow playing, and indoor viewing of animals such as polar bears and penguins when the outdoor temperature is above zero, it is necessary to be in the snow at this time. Therefore, indoor refrigeration equipment suitable for ski resorts and other venues has emerged as the times require; [0003] Generally, the refrigeration equipment used for cooling in ski resorts and other places has a step of returning air from the room when cooling, and also has a step of sucking in fresh air from the outside and cooling the fresh air to send it into the room; but , in the southern region, when the outdoor temperature is high, such as when the outdoor temperature is ab...

Problems solved by technology

[0003] Generally, the refrigeration equipment used for cooling in ski resorts and other places has the step of returning air from the room when cooling, and also has the step of drawing fresh air from the outside and cooling the fresh air to send it into the room; and the step of cooling the air; but In the southern region, when the outdoor temperature is high, such as when the outdoor temperature is above 23 degrees, if the return air with a temperature of around zero or even below zero is directly drawn from the ski resort, and the low-temperature return air is directly discharged, it is easy to cause frost, The phenomenon of freezing also wastes resources, increases energy consumption, and affects the working efficiency of refrigeration equipment
