The water-cooled condenser option is available for facilities equipped with chilled recirculating water systems. This option utilises the cascade refrigeration design to reuse energy produced by an ultra-low freezer, whilst delivering additional energy-savings and high performance cooling. Ideal for material storage in repositories, hospitals, clinics and medical research facilities, the water-cooled system provides a range of benefits.
- Energy efficiency
- Cost saving
- Re-use of energy
- Faster recovery time
- Improved sample security
How It Works
Heat generated from the freezer compartment is transferred to a water circuit using a plate heat exchanger.
Transport the absorbed heat/energy from the freezer.
Possibility to re-use heat/energy for other heat/energy demanding systems.
PHCbi's water-cooled Ultra-Low Temperature Freezers incorporate a double plate heatexchanger that maximises heat energy transfer from the refrigerant to a closed water circuit. As water is more efficient than air at removing heat, the compressor efficiency is improved, meaning that the power consumption of a watercooled ultra-low temperature freezer can be reduced by 15-20% compared to an equivalent air-cooled model. As heat is removed through the water, there are much lower demands on the air conditioning system, resulting in additional savings.
The energy removed by the water cooling system has the potential for use for other purposes within the facility, such as heating water for hand-washing, or heating the building, reducing site-wide energy costs. As well as the environmental and financial benefits, a water-cooled system can also improve freezer performance and sample protection.
