The suction line is attached to the accumulator. This line is cold because of the low pressure the refrigerant (Freon) entering the compressor. It will condensate water vapor in the air. This is a good sign. However if you ever have to add refrigerant to your unit you have a leak. Some people think the refrigerant needs to be added every year. This is false. If a technician has to add refrigerant there is a problem, a refrigerant leak. There are 2 types of refrigerant used in residential hvac units R-22 and D-410A. R-22 is being phased out and and is expensive. R-410A is the new type of refrigerant. Fun fact, Freon is a name brand like frisbee. DuPont calls it Freon. In the hvac industry we call it refrigerant.

Why does ice buildup on tubing around components, and can that cause lower air flow and warmer air coming into house?

@TECTubefilms

4 жыл бұрын

It is usually the other way around. Lower airflow often causes the ice to form. Restrictions such as a dirty filter, dirty evaporator coil, or closing off registers are generally the cause of too low of an airflow. Although, refrigerant pressure can also be the suspect.

@orangeandbluehoosier

The job of the indoor coil in cooling mode is to absorb heat from the conditioned space. If you don't have enough airflow over that coil, it won't absorb enough heat and the temperature will drop below freezing (it's designed to be approximately 40F). An improper charge can also be a cause. In heating mode, the outdoor coil is designed to pick up heat from outside, so it is designed to be 20-25 degrees below the outdoor air temperature. When the outdoor air drops below 50, the outdoor coil is going to be below freezing by design. So, any moisture in the air will start to freeze on the coil and piping. To fix this, heat pumps have a defrost mode, that engages on regular time intervals and the temperature of the outdoor coil. If the defrost mode isn't working correctly, or you have poor air flow (leaves, grass, dirt, patio furniture, etc on the coil) or incorrect charge, will lead to ice buildup as well.

Just out of curiosity so What is the setup for a heat pump condenser in a traditional house? I know for regular AC you have AC condenser outside and then inside you have your gas furnace with coil on top. So what is the setup with heat pump condenser if the heat pump does cooling and heating? What goes inside the house?

The thermostat may need to change or at a minimum be re-wired. In some replacement scenarios... for both A/C or heat pump... the indoor equipment and refrigerant piping cannot be re-used.

You are correct. The heat pump in the video is a Carrier 25HPA and it uses pressure switches. Some of Carrier's heat pumps, such as a 25VNA use both pressure switches and pressure transducers. For those unfamiliar, a transducer will send a specific pressure reading to the circuit board (and possibly the thermostat) to be used to make decisions. A switch will simply open or close at a specific pressure, thereby letting the control system know the pressure is too high, for example, but not telling it what the actual pressure reading is. Switches are lower cost than transducers. Thanks for the correction @movax20h

Also pressure switches are more reliable and can switch higher currents, so they can act as safety switches to stop compressor for example.

The board is outside, because major electrical components of compressor and condenser fan are there, so there is less cables to run to it. Board is under cover and sometimes conformally coated. The boards getting wet are almost never a failure mode. Motors, contactors, capacitors, compressors, clogged lines, leaks, dust on condenser, bad electrical screw connections are usually issues. Also notice that the compressor is cooled by the fan in the unit. As of the insulation on the compressor, it is not exactly insulation. It is sound insulation. So it is not as thermally insulating as real thermal insulation. But yes it does insulate. However this is a second stage compressor afaik, and it moves liquids at much lower temperature in the first place so this liquid makes the compressor cooler during operation. In fact this compressor might need insulation to not freeze up. Just a guess.
