CRAC / Refrigerator&Air-conditioner

Although refrigerators and air-conditioners share the same principle of refrigeration, they are designed as independent products since their invention. Here we introduce CRAC, the Combination of Refrigerator and Air-Conditioner sharing the same indoor cabinet and outdoor refrigeration system. Given that this design requires only one refrigeration system to support the two functions, it will save much room space, which is particularly suitable for small apartments. Moreover, it is promising to significantly reduce the consumption of metals, plastics and cryogen, and eventually protect our environment.
