High Humidity Loads: Conquering the Challenge in Commercial ...During "reheat" or dehumidification mode, the HVAC system will simultaneously operate the compressor to condense and remove air moisture at the evaporator coil while reheating the air to an approximate room temperature prior to discharge. This operation results in a dehumidification mode that reduces humidity while maintaining room temperature.

Air Conditioner heat recover for hot water — northernarizona ...In Lake Worth FL that is probably not true but it depends on how the A/C is achieving their SEER performance. In general, R410a (Puron) performs poorer then R22 when outside temps are above 90 to 95 degs F and better below 90 degs F. R410a has higher compressor output pressure and temperature then R22 which would imply better performance for hot water heat recovery.
Military Spin - Rotor & Wing InternationalRecuperators are described by some skeptics as an attempt to achieve perpetual motion. Recuperators are heat exchangers that capture and exchange exhaust heat to superheat compressor discharge air up to a higher temperature before its introduction into a turbine engine combustor.

Air Conditioner Compressor Troubleshooting & RepairAir Conditioner Compressor Troubleshooting - The average compressor in many residential condensing units are hermetically sealed compressors. Furthermore, the only visible working parts on the compressor are the electrical connections and the copper discharge and suction lines.
Reciprocating Compressors: Startup and Capacity Control ...The most prevalent reason is to adjust the suction flow to match the process demand. The second reason is to save energy. As a rule, capacity control is determined by the compressor discharge pressure. Compressor capacity-control methods are utilized to maintain a required delivery under variable process conditions.
Advances in heat pump systems: A review - ScienceDirectThe scroll compressor is approximately 10 percent more efficient than the standard reciprocating compressor. There are three chief reasons for this improvement . Firstly, the suction and discharge processes are separate, meaning that no heat is added to the suction gas as it enters the compressor in contrast to the reciprocating compressors.
Common Compressor Problems in Your Air Conditioner | Ierna ...Compressor problems that can affect an AC. Bad pressurization: The compressor works through pump action—suction and discharge—to draw liquid refrigerant inside and then compress it into a high temperature gas. However, the suction pressure or the discharge pressure can become too high or too low because of improper mechanical motion.
