DEFINITION: LOOP SYSTEM: The geothermal, or ground source heat pump, has to have contact with the ground to transfer heat from your house in summer, and extract heat to warm your house in winter. The "loop" is the piping system that carries the water heated or cooled by your home, to the ground, one way or the other.
Jul 15, 2015· Air conditioner or heat pump operating temperature diagnostic questions & answers: HVAC system temperature FAQs: Questions & answers about air conditioner or heat pump system temperatures at the equipment, at the cooling or heating coil, at the supply or return registers, & how those temperatures help diagnose HVAC system problems.
A heat pump is a device that transfers heat energy from a source of heat to what is called a heat reservoir. Heat pumps move thermal energy in the opposite direction of spontaneous heat transfer, by absorbing heat from a cold space and releasing it to a warmer one. A heat pump uses external power to accomplish the work of transferring energy from the heat source to the heat sink. The most common …
Jul 02, 2009· Re: Heat Pump temperature drop. When the coil temperature is to high because the system is under charged or dirty or it is running high head pressure because of a dirty condenser, you can't dehumidity nothing,and it can take 3-4 hours to cool the …
Ground-source heat pumps are better dehumidifiers than normal air conditioners, because these systems typically have a larger, flat return coils that conditions and dehumidifies more air than the corresponding coil in an air-conditioning system. Air-source heat pumps have about the same dehumidifying capabilities as air conditioning systems.
A heat pump requires the same annual maintenance as a typical air conditioning system, including cleaning and inspecting the condenser coils, and inspecting and lubricating the fans. A standard air conditioning tune up or summer heat pump tune up can cost around $100.
How to get the best efficiencies Our Technical Director Guy Cashmore explains that whilst the design of the ground side of a ground source heat pump installation is key, for good efficient performance from any heat pump installation, the design of the hot side is equally important. Our Technical Director Guy Cashmore is a regular columnist.
Aug 18, 2008· Re: Measuring temp differential. Just because you set the thermostat to 60 does not mean the AC is going to get colder, its just going to run longer to try to meet that temp. If the supply air coming out of the ducts is under 65 degrees then it is a good assumption that the AC unit can cool the house to 65 degrees if kept running.
Dec 11, 2012· What about temperature rise on Aux heat with the heat strips running? or a gas aux heat unit? Aux heat strips can be typically 5kw to 10kw, the amount of airflow will also change the heat output. Anywhere from 15 to 40 degree diff. could be normal depending on the system.

Jan 09, 2002· Evaluating the performance of a heat pump in heating mode can be very difficult. The typical feedback we usually rely on in the cooling mode to determine how a system is operating (like pressures, subcooling and superheat) is much less valuable in heating mode.
