This creates a temperature gradient between the two fluids, allowing for efficient heat transfer. What are the advantages of using a counter flow heat exchanger? One of the main advantages of a counter flow heat exchanger is its efficiency. The opposite flow of the two fluids allows ...
Just like the energy efficiency ratio(EER),which is the evaluating value for single-speed air conditioner,the Seasonal energy efficiency ratio(SEER)is a value for evaluating the running efficiency of variable-speed air conditioner,the higher the SEER, the more efficient the variable-speed air condi...

The HBC box acts as a heat exchanger, and hot or cold water runs out of it and onto the floor plate, to feed each of the FCUs. R32 refrigerant is typically used between the external condenser units and the HBC boxes serving the zones. ...

To improve the efficiency of the glass furnace and to maintain high temperatures in a melter, a heat recovery device will often be used to recover heat from the melter flue gases and to provide high air preheat temperatures. Two common recovery devices are a regenerator and a recuperator. A...

A comparison of the efficiency of heat transfer in the noted regimes of heat transfer agent motions is made. For the purposes of this comparison, it is proposed to use an averaged value of the function that represents the ratio of efficiencies with heat transfer agent direct flow and ...
Hitherto, it has not been possible to determine the effective power of heat recovery devices but the theoretically calculated recovered heat has had to be accepted without conclusive information on the efficiency of the heat recovery device actually being obtained. According to the invention, a ...
