The cost savings associated with split ductless heat pumps is dependent upon a number of factors including the efficiency condition and location of. Typically the heat transfer efficiency is between 0 6 and 1. In this equation only the definition of mean temperature difference has been made more specific. Heat and energy efficiency.

The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. Shell tube heat exchanger efficiency. Where lmtd is the logarithmic mean temperature difference. Compare costs efficiency installation operating costs and more for electric heat pumps vs gas heating to determine which hvac system is best for your home.

A heat exchanger is a system used to transfer heat between two or more fluids heat exchangers are used in both cooling and heating processes. They are widely used in space heating refrigeration air conditioning power stations chemical plants petrochemical plants petroleum refineries natural. In this paper the heat transfer efficiency is assumed to be 0 95 40. The use of electric heat pumps will actually save you between 1 000 and 2 000 anually in energy costs making it one of the most energy efficient air conditioning and heating systems out there.
