Refrigerant reclamation and recycle unit

A device for demonstrating the operation of gas contaminant testing apparatus and for training persons to use such apparatus. The device can be portable and allows demonstration of and training on testing apparatus in a location removed from the environment in which the gaseous medium and its gaseous and vaporous contaminants are normally found. The device uses very small contaminant samples for demonstration in order to minimize personnel exposure and inadvertent or deliberate releases to the environment. The device allows the substitutions of, for training and demonstration purposes, a harmless gaseous medium for the actual gaseous medium of interest. In a preferred embodiment, designed for demonstrating the operation of a refrigerant contaminant testing apparatus, air is susbstituted for refrigerant as the gaseous medium in which contaminants are entrained when using the device. In that embodiment, air is caused to flow through a container holding a contaminant sample of interest. Vapors of the contaminant mix with the air and the mixture is caused to flow through a refrigerant contaminant testing tube connected to the device, resulting in testing tube indications that emulate the indications to be expected when testing a refrigerant sample containing the contaminant. More than one sample container can be fitted into the device and there can be one or more tester connections. The sample containers are interchangeable so that demonstrating a variety of contaminants is possible. The device may be used as an adjunct to gas testing apparatus for testing a gas sample collected at a remote location.

Device for gas contaminant tester training

A demonstration device for simulating the operation of a heat pump system comprising a schematic representation of a heat pump system, a plurality of lamps and associated electrical circuitry adapted to illuminate portions of the schematic representation to simulate the operation of the heat pump system in various modes of operation, and to simulate refrigerant flow and the phase state and temperature of the refrigerant at different places in the system, and associated explanatory panels for alternatively demonstrating the operation of the electrical circuitry of the heat pump system, or indicating the mode of operation of the system.
