Patent ID: RE39287

Claim:
A temperature control system for use in a cabinet disposed with an ambulance or other medical service vehicle, wherein the cabinet stores medical items and said system maintains the cabinet interior and medical items within a particular temperature range, said system comprising: a temperature sensor disposed within the cabinet interior to measure the cabinet interior temperature and to generate a temperature signal indicating the measured cabinet interior temperature; at least one heat pump partially disposed within the cabinet interior to heat or cool the cabinet interior; and a controller assembly to enable selection and entry of the particular temperature range into said system and to generate control signals to control each of said at least one heat pump, wherein said particular temperature range is selectable from anywhere within a larger range of temperatures attainable in the cabinet interior and said controller assembly controls each of said at least one heat pump to heat or cool the cabinet interior as required in response to comparison of the temperature signal received from said temperature sensor with the selected particular temperature range to maintain the cabinet interior within said selected particular temperature range, and wherein said controller assembly includes a control console including: a numerical display unit for selectively displaying at least one temperature in said selected particular temperature range and said measured cabinet interior temperature indicated by said temperature signal, wherein said selected particular temperature range and said measured cabinet interior temperature are alternatively displayable on said numerical display unit.
