Thank you for your reply. I am speaking of adding a reversing valve to a straight air appliance. These are normally coupled with a furnace as package or split. The very reason they are not heat pumps. I say they can and should have been heat pumps all along and if we upgrade them they will be...

I agree with you on the complication of the environmental impact. A study is warranted in my opinion. I think when something is better, it should be done. A hybrid heat pump is better than a heat pump with electric back up and a furnace alone. Most package gas are only 80 percent efficient. The...

In the case of reciprocating compressors, a suction accumulator would be beneficial. Heat pumps benefit from scroll compressors and R410a and crankcase heaters. Scroll compressors don't need suction accumulators. A Sporlan biflo txv is needed to feed the outside coil. The brazing is not too...

I am a refrigeration technician with a fascination for heat pumps. I wonder if we can make two systems in parallel. The Carnot heat engine is used to describe the steam locomotive. I want to use a different fluid with a lower boiling point to create a heat engine using a refrigeration cycle...

I have found large amounts of non-condensables in two different systems in my career. It is the worst of all variables because it is out of the norm and difficult to catch in the act. It works sometimes is the electrical equivalent of a short circuit. The air or nitrogen will stop all progress...

The refrigeration process is used in air conditioning to dehumidify and control temperatures in homes and buildings. The heating industry preceded the air conditioning business and many evaporator coils were placed on top of furnaces to create split systems and utilize existing ductwork. The...
