Title:
A METHOD OF MEASURING THE REFRIGERANT RECOVERED AND A REFRIGERANT RECOVERY AND RECHARGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/034840
Kind Code:
A3
Abstract:
A method of measuring weight of the refrigerant recovered and a device for refrigerant recovery and recharge (10) is disclosed. A connection is established between the refrigerant recovery path (20) and the refrigerant recharge path (22). Refrigerant is filled in the refrigerant recovery path (20) and the refrigerant recharge path (22). Once the refrigerant occupies the all components of the refrigerant recovery and recharge device (10), weight of the refrigerant storage tank (18) is measured. The weight of the refrigerant storage tank (18) is measured once before the recovery of the refrigerant from the refrigeration equipment (12) and once after recovery of the refrigerant from the refrigeration equipment (12). Difference in the weights measured before recovery and after recovery is calculated to a get the amount of refrigerant recovered.
