20140137579 | Refrigerant Recovery and Recharge Device - A refrigerant recovery and recharge device and a method to recharge oil to refrigeration equipment is disclosed. The refrigerant recovery and recharge device comprises a valve block which is adapted to establish fluid communication between the device and refrigeration equipment and a recharge path adapted to recharge oil to the refrigeration equipment through an outlet in the valve block. The device further comprises at least a first oil container and a second oil container and the valve block comprises a valve with a first inlet and a second inlet. The first oil container is in fluid communication with the first inlet and the second oil container is in fluid communication with the second inlet to recharge oil to the refrigeration equipment. The method for recharging oil recharges oil either from the first oil container or the second oil container in dependence of the type of fuel used in the vehicle. | 05-22-2014 |
20130247596 | METHOD OF MEASURING THE REFRIGERANT RECOVERED AND A REFRIGERANT RECOVERY AND RECHARGE DEVICE - A method of measuring weight of the refrigerant recovered and a device for refrigerant recovery and recharge device is disclosed. A connection is established between the refrigerant recovery path and refrigerant recharge path. Refrigerant is filled in the refrigerant recovery path and the refrigerant recharge path. Once the refrigerant occupies the all components of the refrigerant recovery and recharge device, weight of the refrigerant storage tank is measured. The weight of the refrigerant storage tank is measured once before the recovery of the refrigerant from the refrigeration equipment and once after recovery of the refrigerant from the refrigeration equipment. Difference in the weights measured before recovery and after recovery is calculated to a get the amount of refrigerant recovered. | 09-26-2013 |
20130205810 | METHOD TO INDICATE FILTER REPLACEMENT IN A REFRIGERANT RECOVERY AND RECHARGE DEVICE - A refrigerant recovery and recharge device is configured to be connected to refrigeration equipment. The device includes a filter configured to filter refrigerant and removal contaminants in recovered refrigerant. The filter includes a fuse configured to indicate when the filter should be replaced. | 08-15-2013 |
