The apparatus of the present invention comprises a housing defining a closed interior volume of a size sufficient to accommodate the appliance, a first heat sink located within the housing, a second heat sink located outside the housing, a reversible heat pump disposed between and in heat conductive engagement with each of the first and second heat sinks, a temperature sensor located within the housing, and electronic circuitry to actuate the heat pump in either of a first cooling mode or a second heating mode in response to predetermined temperature set points sensed by the temperature sensor within the housing. The apparatus also includes an appliance support tray and a holding bracket that engages and maintains the tray in spaced relation within the housing. A pressure equalizing diaphragm is also employed to accommodate pressure changes within the housing.

An apparatus for maintaining an operational environment for an environmentally and temperature sensitive appliance, comprising: a housing defining a closed interior volume of a size sufficient to accommodate said appliance; a first heat sink located within said housing; a second heat sink located outside said housing; a reversible heat pump disposed between and in heat conductive engagement with each of said first and second heat sinks; a temperature sensor located within said housing; electronic circuitry configured to (i) receive a first signal from said temperature sensor when the temperature within said volume exceeds a first set point and actuate said heat pump in response to said first signal to transfer heat from said first heat sink to said second heat sink, and (ii) receive a second signal from said temperature sensor when the temperature within said volume falls below a second set point and actuate said heat pump in response to said second signal to transfer heat from said second heat sink to said first heat sink; and a pressure sensitive diaphragm disposed in a wall of said housing and responsive to changes in the pressure within said housing to accommodate expansion or contraction of the gas volume within said housing to thereby minimize gas flow into or out of said housing.
