A temperature control system having an increased heating performance. The system includes a compressor adapted to compress a fluid, a heat exchanger coupled to the compressor such that compressed fluid moves from the compressor to the heat exchanger, and a pressure regulating valve positioned between the compressor and the heat exchanger such that compressed fluid from the compressor moves through the valve before reaching the heat exchanger. The pressure-regulating valve is designed to stay in a closed position until the pressure of the fluid from the compressor reaches a desired value. By virtue of this design, the pressure of the fluid in increased, thus resulting in an increased in the temperature of the fluid. Upon reaching the desired pressure, the valve opens to allow the highly-pressurized fluid to flow to the heat exchanger.
