A cooling jacket enables a portion of the pumped liquid or an external liquid to be circulated around the motor stator housing. This absorbs excess heat by forced convection, ensuring efficient cooling of the pump.
COP (Coefficient of performance)
Coefficient of performance (COP), is an expression of the efficiency of a heat pump. When calculating the COP for a heat pump, the heat output from the condenser (Q) is compared to the power supplied to the compressor (W).
Corrosion can occur on external and internal surfaces of pipes, tanks and radiators. In the design phase various issues have to be considered such as pipe material, insulation, medium, humidity and air purging etc.
COSP (Coefficient of system performance)
The COSP of a heat pump is based on the total heat extracted (also referred to as Q) in relation to the energy supplied to the heat pump (also referred to as W).
Cross flow heat exchanger
A cross-flow heat exchanger exchanges thermal energy from one airstream to another in an air handling unit (AHU). Unlike a rotary heat exchanger, a cross-flow heat exchanger does not exchange humidity and there is no risk of short-circuiting the airstreams.
