Reduced water heating costs as you cool milk
Milk refrigeration works by extracting calories from milk by means of a cooling unit. The calories extracted from the milk are removed via a condenser and are lost. It is possible to recover this energy to heat water for the dairy. To achieve this, a heat exchanger containing refrigerant/water is installed in the cooling circuit between the compressor and the heat recovery water-holding tank.
The bulk tank compressor compresses gas from the evaporator, which increases its temperature. The hot gas loses part of its calories to the water when passing through the heat exchanger. The resulting cooled gas reverts to the liquid state in the condenser prior to being once again injected into the evaporator to extract
calories from the milk.
The warmed water is stored in a heat recovery water holding tank which can then supply a water heater. Water from the lower part of the heat recovery water holding tank is pumped by the circulation pump through the brazed plate heat exchanger before being raised into the upper part of the heat recovery water holding tank. This operates on a continuous flow principle whilst the bulk tank is cooling. Warm water is available in a few minutes and is released to the existing water heater when required.
