    is to compensate for other thermal loads so that the cabin temperature remains within the acceptable comfort range. In cold weather conditions‚ positive AC load (heating) is required for the cabin. Inversely‚ in warm conditions‚ negative AC load (cooling) is needed for maintaining the comfort conditions. The actual load created by the AC system depends on the system parameters and working conditions. In this work‚ it is assumed that an AC (or heat pump) cycle is providing the thermal load calculated

    temperature difference)‚ the "heat pump" is named by analogy. A heat pump always moves thermal energy in the opposite direction from temperature‚ but a heat pump that maintains a thermally conditioned-space can be used to provide either heating or cooling‚ depending upon whether the environment is cooler or warmer than the conditioned-space. When pumps are used to provide heating‚ they are used because less input from a commercial-energy source is required than is required for newly-creating thermal
