2010-12-15 · The design and installation of a suction line is one of the most critical parts of a whole refrigeration system (see Info-Tec 12). Floodback/Flooded Starts Flooding is the continuous return of liquid refrigerant as droplets in the suction vapor instead of all super-heated vapor.

Thermostatic Expansion Values: A Guide to Understanding .

Understanding TXVs. Since the minimum efficiency regulation changed to 13 SEER in January 2006, most OEM systems now incorporate a thermostatic expansion valve (TXV) style metering device as the standard for air conditioning systems. It is now extremely important for the HVAC technician to understand the design and operation of this type of valve.

Basic Refrigeration Cycle

The refrigeration cycle tells us if there is air in the air conditioner units, what to repair after troubleshooting the refrigeration system, if there is enough air conditioner Freon, or if the filter is dirty. We could know the entire thing by knowing the pressure and temperature of the evaporator, condenser, and compressor.

Refrigerant overcharge effects: Air Conditioner / Heat .

Refrigerant charge quantity for air conditioners & heat pumps: This air conditioning repair article series discusses the the diagnosis and correction of abnormal air conditioner refrigerant line pressures as a means for evaluating the condition of the air conditioner compressor motor, which in turn, is a step in how we evaluate and correct lost or reduced air conditioner cooling capacity.

The Role of the Suction Line Accumulator

2001-8-29 · A suction line accumulator prevents compressor damage from a sudden surge of liquid refrigerant and oil that could enter the compressor from the suction line. The suction line accumulator is a temporary reservoir for this mixture, designed to meter both the liquid refrigerant and oil back to the compressor at an acceptable rate.
