How to Identify Low Evaporator Heat Load, TXVThe low heat load condition could cause the evaporator coil temperature to be very cold. Ice or frost may form on the evaporator surface and suction line surface. The compressor shell may sweat and the hot gas temperature will be cool. Repair Procedure. Thaw the evaporator coil if frost or ice has formed. Inspect the return air filter and ...
Evaporator Coil Leaks — What Causes This A/C Issue?Evaporator coil leaks must be diagnosed and repaired by a professional. However, the homeowner can do a few things to make them less likely. Sealed inside your indoor air handler, the evaporator coil component of the air conditioner performs the heavy lifting of heat transfer that cools your home.
Air Conditioners & Heat Pumps: Dirty or Blocked Air ...This air conditioning repair article discusses the problem of dirt or debris blockage of the air conditioning system's cooling coil or evaporator coil in an air conditioning system air handler, how the dirt gets there, what problems it causes, how to clean a cooling coil (or evaporator coil), and how to prevent future dirt on the coil.

Evaporator - WikipediaThis works in the closed A/C or refrigeration system with a condenser radiator coil that exchanges the heat from the coolant, such as into the ambient environment. A different kind of evaporator can be used for heating and possibly boiling a product containing a liquid to cause the liquid to evaporate from the product.
Top 5 Causes of Frozen AC Coils - AristaIf the water is stuck in one place because of a clogged pipe, it can freeze. This is especially true if the obstruction happens near the evaporator coil, the coldest part of the AC. A blocked condensate line can cause the water, and subsequently the coils to freeze. 4. Malfunctioning thermostats are a cause of frozen AC coils

6.9 Flooded evaporators - SWEPUnlike in a direct expansion (DX) evaporator, the refrigerant is not fully evaporated and superheated at the flooded evaporator outlet. The leaving refrigerant flow is a two-phase mixture with typically 50-80% gas. Flooded evaporators, which are sometimes called wet evaporators, are divided into forced-flow evaporators and thermosiphon evaporators.
collecting oil in evaporator [Archive] - Refrigeration ...The evaporator's tailpipe will be oil logged and the inside of the tubes will be coated with oil. The remote bulb of the TXV at the evaporator outlet will have a hard time sensing a true evaporator outlet temperature because of the reduced heat transfer through the line. The TXV will hunt. As a result, constant superheat will not be maintained.
