Description

Technical Field

[0001] The utility model specifically relates to a refrigerant storage device based on temperature insulation. Background Art

[0002] Refrigerants generally refer to substances used to transfer heat in refrigeration and air conditioning systems. These substances absorb and release heat through a cycle of evaporation and condensation, thereby achieving the effect of lowering or raising the temperature. Common refrigerants include Freon, ammonia, hydrofluorocarbons, methane, etc. Different refrigerants have different properties and uses, and the choice depends on the application requirements and environmental considerations.

[0003] The existing refrigerant storage tank is relatively simple, with only a thin shell made of steel, which does not provide thermal insulation against the external temperature. When the external heat is large, the heat will be transferred to the inside of the tank, causing the refrigerant to vaporize due to the heat, increasing the internal pressure of the tank and causing the risk of damage. It cannot effectively isolate the external heat. For this reason, we propose a refrigerant storage device based on thermal insulation. Utility Model Content
