Abstract

The invention discloses a steel cylinder for quickly adding refrigerant, and relates to the field of pressure containers. During operation of adding the refrigerant by using an existing steel cylinder, the temperature and the pressure of the refrigerant in the refrigerant steel cylinder are reduced, and then the refrigerant is added slowly. Due to the adoption of the steel cylinder for quickly adding the refrigerant, a heat conducting base is arranged at the bottom of the refrigerant steel cylinder, and an electric heater is used for heating to raise the temperature and the pressure in the steel cylinder. The steel cylinder for quickly adding refrigerant can ensure that the pressure in the steel cylinder is raised when adding the refrigerant, can be used for quickly adding the refrigerant, is simple in structure and low in cost, can be used by only turning on the power, and is convenient to use.

Description

technical field [0001] The invention relates to the field of pressure vessels, especially refrigerant cylinders. Background technique [0002] In the maintenance of refrigeration and air conditioning systems, it is often necessary to add refrigerant. In the operation of adding refrigerant, since the refrigerant evaporates and absorbs heat in the liquid filling pipe, liquid filling valve and steel cylinder, etc., the temperature and pressure of the refrigerant in the refrigerant steel cylinder decrease, and the pressure difference between the pressure in the steel cylinder and the pressure in the refrigeration system decreases. The flow rate of the refrigerant becomes slower, and as the evaporation of the refrigerant increases, the rate of adding the refrigerant becomes slower and slower. Especially when adding refrigerant to the low-pressure side of the refrigeration system, in order to prevent liquid shock, gas refrigerant should be added. At low temperature and low pressu...
