The Coefficient of Performance (COP) is the performance rating used primarily in heat pumps. It is defined as the ratio of heat output to the amount of energy input of a heat pump. It compares the heat produced by the heat pump to the heat obtained from resistance heat. COPs vary with the outside temperature; as the temperature falls the

Varying the blower speed with an electronic variable speed drive provides for precise control over the pressure and temperature rise, and therefore over the rate of evaporation. 2 The steam condensate (Cc) from dairy industry TVR and MVR evaporators contains evaporated water from the feed process stream and this is known colloquially as cow water.

comparison of cooling systems rather than comparing full-speed EER. Since a chiller, like most air conditioners, only needs to run at full capacity a small percentage of the time, the IPLV and NPLV ratings are far more important than the full-speed numbers.

Collection Systems Technology Fact Sheet: Sewers, Lift Station

Because variable-speed pumping allows lift station discharge to match inflow, only nominal wet-well storage volume is required and the well water level is maintained at a near constant elevation. Variable-speed pumping may allow a given flow range to be achieved with fewer pumps than a constant-speed alternative. Variable-speed stations also ...
