The compressor in an HVAC refrigeration system
Compressor Rebuild - This freshly rebuilt reciprocating compressor is destined for a large commercial chiller. Chillers chill water for air conditioning. Compressors compress refrigerant vapor and pump the compressed refrigerant to the condenser to be condensed into a liquid. It is an essential component of the refrigeration system.
The compressor provides compression which is an integral part of the refrigeration process. The old compressor was condemned for electrical burnout. The windings in the old one burned up and caused the circuit breaker to trip. (more…)

Heat Pump Thermostats - To the average person a heat pump thermostat can be a very complicated thermostat compared to the typical thermostat which serves an air conditioning system with gas, electric, or an oil furnace. Of course, the heat pump thermostat typically has more wire terminations than the regular thermostat.
It has more switches to control emergency heat, and some even have lights, which will indicate that the auxiliary heat or emergency heat is functioning. Most heat pump thermostats are two-stage thermostats for the heating mode and a single stage for the cooling mode.

Learning the Basics of HVAC - To understand air conditioning and heat pump applications you will need to study refrigeration. Both air conditioners and heat pumps use refrigeration to move heat. Air conditioners move heat outside in the summertime using the process of refrigeration. Furthermore, heat pumps move heat in both directions (to the inside in the winter and to the outside in the summer) using the principles of refrigeration. (more…)
