Abstract (en)
[origin: WO2014165248A1] A refrigerant recovery unit with improved charging accuracy is provided. A service hose that includes a service coupler and a check valve A refrigerant recovery unit with improved charging accuracy is provided. A service hose includes a service coupler and a check valve assembly. The assembly is disposed proximal to the service coupler and includes a recovery flow and recharge flow path. The assembly is configured to provide a substantially free flow of refrigerant and also configured to provide a predetermined cracking pressure in response to the refrigerant being urged to flow along the recharge flow path. The disclosure includes thermally conditioning the interior of the service hoses based on one or more temperature reading(s) and/or based on a function and may be achieved by a heater along the length of the hose, recirculating refrigerant, and/or through a parallel line of heated liquid.
