Abstract: A cooling system includes a cooling device, a controller and a defrosting unit. The cooling device has a compressor, a condenser, an expander, an evaporator, a cooling channel and a coolant. The coolant is functioned in the evaporator to thermally exchange with a working fluid in a pipe. The controller is adapted for controlling the temperature of the working fluid by controlling the cooling device. The defrosting unit has a switch disposed on the cooling channel and located between the compressor and the condenser, and a defrosting channel connected with the switch. After passing through the switch, the coolant is optionally fed to anyone of the cooling channel and the defrosting channel. After flowing through the defrosting channel, the coolant passes through the evaporator and then flows back to the compressor. As a result, the cooling system is capable of fast defrosting without using a heater.

Abstract: An adaptive temperature control system for cooling a working fluid at a target temperature includes a cooling device and a controller. The cooling device includes a compressor having a motor, a condenser having a fan, an expander, an evaporator, a coolant, and an inverter electrically connected with the motor of the compressor. The coolant in the evaporator is functioned to thermally exchange with the working fluid, thereby cooling the working fluid passing by the evaporator. The controller controls the rotary speeds of the motor and the fan according to a plurality of system parameters, optionally including the target temperature, a temperature in the evaporator, a mass flow of the working fluid, inlet and outlet pressures of compressor, and a temperature of the working fluid obtained at a sense position where the working fluid has passed by the evaporator.
