Abstract
A temperature control device for a constant temperature chiller unit or a vending machine is provided. Thermal medium fluid such as water in the chiller unit is accurately controlled under starting mode, heating mode and cooling mode. Thermal medium fluid such as air in the vending machine is conveniently controlled in winter mode and summer mode. In the device, a heat exchanger is interposed within a compression circuit, and a bypass circuit is disposed at the downstream side of a pump so that through the bypass circuit thermal medium fluid receives heat from the heat exchanger. Thus, the temperature of thermal medium fluid supplied to an external secondary heat load is controlled.
