Refrigerated truck water ice and salt ice refrigeration principle

At atmospheric pressure, the melting point of ice is 0Â°C. When the ice melts, the heat absorption is 334.8 kJ/kg. Adding salt to the water ice can reduce its melting point. Within a certain range, the more salt in water ice, the lower the melting point. Experiments have shown that when the mass of salt added is 29% of the mass of water ice, the melting point of the mixture can reach a minimum value of -21.2Â°C. If you add more salt, the melting point no longer declines. The salt ice of different compositions is usually selected based on the proper temperature of the refrigerated cargo. For example, using salt ice with a salt content of 22%, the temperature in the compartment can be maintained at -18~-13Â°C.

The water ice refrigeration device has a low investment and a low operating cost, but ordinary water (salt) ice has a small amount of heat absorption per unit mass, and the cooling in the vehicle compartment is limited. In addition, melting of salt ice will pollute the environment and food, corrode the car and the value of goods damp. Therefore, water (salt) ice refrigeration is mainly used for refrigerated transportation of fish and other aquatic products.
