There will always be a third port on a heat pump and that is always the suction port. It comes right off the compressor, or close to it.

What are the parts of a heat pump called?
There are three basic parts of a heat pump – the condenser, compressor and evaporator. This type of system is referred to as an air-to-air transfer system or closed-circuit heat pump. There are other parts of a heat pump, but these three components are the most fundamental and easiest to understand.
What are the two parts of a heat pump?
A heat pump consists of two main components: an indoor air handler and an outdoor unit similar to a central air conditioner, but referred to as a heat pump. The outdoor unit contains a compressor that circulates refrigerant that absorbs and releases heat as it travels between the indoor and outdoor units.
Where is the true suction line located?
Where is the true suction line located? The suction line is to return gas to the compressor. It is between the evaporator and compressor on a standard cooling system and between the reversing valve and the compressor on a heat pump.
What should the pressures be on a heat pump?
On a properly functioning R-22 system running in heat mode in 40-degree weather, the suction pressure tends to be around 40 PSIG. This guideline obviously doesnt work on an R-410A system or any other refrigerant. A more applicable guideline is 20-25˚ suction saturation below outdoor ambient temperature.
What is true suction on a heat pump?
The suction line is to return gas to the compressor. It is between the evaporator and compressor on a standard cooling system and between the reversing valve and the compressor on a heat pump. On a split system heat pump, the connecting lines are the vapor line and the liquid line.
What is the most important component of heat pump?
There are four important components of the heat pump: compressor, condenser, expansion valve and the evaporator. In the refrigerator and air conditioner the evaporator performs the most important function of cooling or freezing, but in heat pump the condenser performs the most important function of heating the room.
Where should a heat pump be located?
Typically, the best location for a heat pump condenser is a shady area, away from direct sunlight. The condenser also needs to be installed directly on the side of or behind the home, away from any shrubbery or vegetation (which could interfere with airflow.)
What is the most important component of a heat pump?
10 Cards in this SetWhen a substance changes directly from a solid into a gas, it has undergone _____.sublimationThe most important component of a heat pump is the ____.RefrigerantThe temperature at which a liquids vapor pressure equals atmospheric pressure is the _____ point.Boiling7 more rows
What is the only true suction line?
The suction line is to return gas to the compressor. It is between the evaporator and compressor on a standard cooling system and between the reversing valve and the compressor on a heat pump. You would have one on the true suction, one on the liquid and one on the vapor.
What does the suction line connect to?
The suction line connects the evaporator to the compressor, the discharge line connects the compressor to the condenser, and the liquid line connects the condenser to the expansion device. The expansion device is typically located at the end of the liquid line, at the inlet to the evaporator.
How do I know if my heat pump is low on refrigerant?
Note the following signs that can signal that your heat pump is low on refrigerant: leaking, icing, and inefficient performance.Leaking Heat Pump. Even though a heat pump uses refrigerant to cool or heat a home, the refrigerant doesnt dissipate during regular operation. Icing. Inefficient Performance.Oct 15, 2016
How do I know if my heat pump is overcharged?
In summary, there are seven symptoms or telltale signs of a system that has too much refrigerant.High discharge temp.High subcooling in the condenser.High pressures in the condenser.Higher condenser splits.Normal-to-high evaporator pressures.Normal superheats.High compression ratio.Aug 6, 2018
What are the 5 major components in a heat pump?
Heat pumps all have the same basic components. These components consist of a pump, a condenser, an evaporator, and an expansion valve.
What are the four major working parts of a heat pump?
The most common design of a heat pump involves four main components – a condenser, an expansion valve, an evaporator and a compressor.
Do you need a heat pump for every room?
Do I Need a Ductless Unit in Every Room of the House? No. While you wont need a single indoor unit for every room in the home, the outdoor unit does attach to multiple indoor wall-mounted units. In most homes, this typically means having indoor units in main living areas.
What is the purpose of a suction line?
The suction line connects the evaporator to the compressor, the discharge line connects the compressor to the condenser, and the liquid line connects the condenser to the expansion device. The expansion device is typically located at the end of the liquid line, at the inlet to the evaporator.
What causes the suction line to get hot?
The external suction line running hot means its running on heat mode. The real suction line is inside the unit and runs between the reversing valve and compressor, that part shouldnt be hot at any time.
