Abstract
A fluidized bed includes an air blower, a heater, an air/air heat exchanger with auxiliary fans, and an air/cold water heat exchanger. The fluidized bed includes a remotely disposed portable water chiller that provides the cold water for circulating in the air/cold water heat exchanger. The water chiller includes a water refrigeration unit and a water pump. Flexible tubing carries cooled water from the water chiller to the air/cold water heat exchanger and relatively warmed water from the air/cold water heat exchanger to the water chiller. Each of the free ends of the tubing, the water chiller, and the air/cold water heat exchanger, is provided with mating male or female connectors to enable the tubing to be selectively connected and disconnected between the water chiller and the air/water heat exchanger. A programmable EPROM uses temperature information from temperature sensors and the operating characteristics of the heater, air/air heat exchanger, fans, air/water heat exchanger, and water chiller to control the operation of the heater, the fans, and the water chiller for optimum efficiency in maintaining a desired temperature of the patient support surface under the extant temperature conditions in the environment of the fluidized bed.
