Abstract: An air-cooling water chiller includes a heat exchanger, a water-cooling system, and a refrigeration system. Heat is exchanged between the water-cooling system and the refrigeration system through the heat exchanger, and the refrigeration system and the water-cooling system are arranged in an up and down direction. The heat exchanger is embedded in the water-cooling system and leans towards the refrigeration system. The refrigeration system and the water-cooling system are arranged separately, so that heat dissipations of the refrigeration system and the water-cooling system do not interfere with each other, and pipelines do not intertwine with each other, making the later maintenance very convenient and simple. In addition, the refrigeration system and the water-cooling system are arranged in an up and down direction, so that an occupation area is small, making multiple systems convenient to be arranged in parallel for later.

Abstract: An air-conditioning, system includes a cabinet with a partition dividing an internal space of the cabinet into an indoor compartment and an outdoor compartment. An evaporator, a compressor and an internal fan are disposed in the indoor compartment. A condenser and an external fan are disposed in the outdoor compartment. The cabinet is provided with an internal air inlet corresponding to the internal fan, an internal air outlet corresponding to the evaporator, an external air inlet corresponding to the external fan, and an external air outlet corresponding to the condenser. The air-conditioning system is of a cabinet structure as a whole, has a small size and occupies a small space. An air flow of the internal fan is completely separated from an air flow of the external fan, so that internal circulating air and external circulating air are effectively prevented from being mixed, and the refrigerating effect is improved.
