Sistem Sirkulasi Pertukaran Panas Media

The energy required for the cooling and heating of the food is driven by the circulating pump and transmitted to the shelf through the heat exchange medium, and then to the food. The cold source for food cooling is provided by the refrigeration system, the heat source for food heating is provided by the heating tank, and the switching between cooling and heating is accomplished by controlling the electromagnetic valve switch of the cold source and the heat source. When the temperature rises, the steam enters the heating medium of the heating tank, and the mixing ratio of the heating medium from the heating tank and the return heating medium of the shelf is adjusted by the pneumatic three-way regulating valve, and the opening and closing of the cooling water solenoid valve of the plate heat exchanger is controlled to control the shelf.
