A chiller is a machine that is designed to cool water or water mixtures in a closed circuit. The unit consists of a refrigerant circuit and a cooled water circuit. The refrigerant circuit is filled with refrigerant and the water circuit with water. These two fluids, which never come into direct contact with each other, exchange heat in the evaporator, where the liquid refrigerant evaporates as it absorbs the heat removed from the water. The colder water then proceeds to the outlet of the unit. When integrated in a closed cooling circuit, the chiller cool, circulates and re-uses the constant volume of the water.
The refrigerant circuit consists of four main parts: the compressor, the condenser, the expansion valve and the evaporator. The circuit is filled with R 407 C refrigerant. The connecting piping is made of copper. The water circuit of the Hyperchill chillers comprises a water accumulation tank, a cooling water circulation pump and a water by-pass pipe.
