Abstract: System, apparatus and methods for measuring air conditioning output temperature to ensure the proper amount of refrigerant for recharging an A/C vehicle coolant system, such as an automobile coolant system, are disclosed. In one aspect the disclosure features a system for servicing a vehicle coolant system, the system comprising: (a) a temperature sensor configured to transmit air vent temperature information at an output air vent of an air conditioning system within a vehicle passenger compartment, (b) a portable electronic computing device configured to receive the air vent temperature information and transmit actuating commands, and (c) a control unit in fluid communication with a pressurized canister containing a refrigerant, the pressurized canister including a plunger valve, the control unit being configured to actuate the plunger valve in response to actuating commands received from the portable electronic computing device.

Abstract: Air conditioning temperature measurement device for use with a valve actuated refrigerant recharge assembly operates in conjunction with a pressurized refrigerant bottle and a-remote temperature sensor enabled by radio frequency (RF) wireless communication. Sampled temperatures at an output vent of an air-conditioned cabin and rate of temperature change at the inlet modulate recharge of refrigerant into low pressure side of a phase change A/C control system. Automated sensing of the rate of temperature change in an air conditioner outlet vent, and modulation of refrigerant refill rate, ensure sufficient refrigerant is introduced to improve cooling efficiency while overfill is prevented by refrigerant valve control as rate of temperature change approaches a parabolic minimum.
