Reverses the flow of refrigerant through the system so it absorbs the heat from the outside ambient air and then rejects the heat through the evaporator and into your duct work.

What component allows heat pump to switch between heating and cooling modes of operation?
the reversing valve is what actually changes the refrigeration cycle from heat to cool. the reversing valve receives its signal from the thermostat.
Can you replace your straight cool AC condensing unit to a same size unit with heat pump?
Hi, Good question and the answer is ( YES! ) as long <<<< as you are not taking up any fancy ideas of using it as a heat pump. Wire it in and set the reversing valve to stay on cool cycle and never reverse to heat and viola. Some units use energized reversing valve during cool and some de-energized. Its easy to find out. Just try it. Hope this helps: Jimiwane
How do you pump down a heat pump unit?
The process of pumping down a heat pump is quite simple. First you should switch the unit into air conditioning and put your compound gauge on the suction line. Make sure the unit is running. Then valve off the discharge line and watch your gauge pressure. When it pulls itself down into a vacuum the heat pump is pumped down within itself. Make sure to valve off the suction line to make sure no refrigerant is released back into the air handling unit. You should now be able to lay some wet rags on the valves to protect them if you desire to sweat the unit away from the line set.
What is heat pump?
A heat pump is one part, of a two part heating and cooling system and can be used as the primary heating unit in mild winter locations. They can also be used to supplement other heating systems where the temperatures are sub-freezing for longer time periods. Heat pumps also are used in summer for cooling. Basically, the way the system works in cooling mode is the same as most any other AC system. When winter comes it essentially runs the system in reverse to produce heat instead of cooling. The advantage is that it is very cheap to run. The biggest two disadvantages are the compressor has to run during both seasons, causing wear... and ... after you get to about 26 degrees F., the heat pump needs auxiliary heat (gas or electric coil) to warm your house. For most warmer climates they are the best choice. Speak with an HVAC professional to determine your region's best heating option.
Which valve is the preferred valve to use as flow control valve at the pump discharge 8 inch size ball valve can be used for the same application?
I would use a butterfly valve to set the flow and a pitot tube to measure it. Nexus Valve makes a good one and it is price competetive as well.
Is a heat pump and heat exchanger the same thing?
No they are not. In fact a heat pump contains within it a heat exchanger/coil. A heat pump is reverse refrigeration. A heat exchange, exchanges heart from a heat source to a conditioned space (the area you want heated). While a heat pump uses a heat exchanger to supply heat to the conditioned space. Reverse refrigeration uses the air conditioner in reverse(you know how heat comes if the back of yhe air conditioner, well when it's in reverse that heat is used to heat a home in winter months.
What part of an HVAC system switches the unit from air conditioning to heat and heat to air condtioning?
In HVAC (heating, ventilating, air conditioner) A thermostatic switches the unit from cooling to heat. In Heat pump unit it's the four-way valve or reverse valve. However, the thermostatic still controls it.
Which component is typically used on a conventional heater and not a heat pump?
A heat pump is basically an air conditioner that can work in reverse, heating the home. All the parts in the burner and burner cabinet are not found in a heat pump. These include the heat exchanger, burner ports, gas valve, igniter, flame sensor, combustion blower, pressure switches, and manifold.
How does a heat pump use freon to heat?
A valve is used to reverse the flow of freon. In the heat mode, the high or hot side gas is pumped to the indoor unit, The low or cold side is pumped to the outdoor unit. The valve is reversed for the cool mode. Pumping cool gas to the indoor unit and hot gas to the outdoor unit.

Where is the oil pressure relief valve on an LS2?
The high oil pressure relief valve is located in the oil pump

Where is the oil pressure relief valve located on 4.3 gm?
It is built into the oil pump/ Part of the oil pump.
Where is the pcv valve located on a 1998 Chevy Cavalier?
its on the right side of the valve cover, near the power steering pump.
How does a split system heat pump work?
The reversing valve switches the flow of refrigerant from cool to heat inside and outside the home.
How do you bleed diesel pump on vauxhall frontera?
open bleed valve on top of distribution pump, crank engine till fuel squirts from valve, tighten valve, turn over couple times. Add heat and fire up.
Where must a suction line be placed in a heat pump after a motor burnout?
between the comp and the reversing valve
