Refrigerant filter drier canisters This article discusses when, where, how and why refrigerant driers are installed on refrigeration, air conditioning and cooling systems. Our photo at page top shows the typical location of a refrigerant dryer canister at the compressorcondenser component of a split system air conditioning system. Green links show where you are.

Once an air conditioner or heat pump system refrigerant leak has been repaired, it will be necessary to flush the refrigerant piping system usually using nitrogen, pull a new vacuum on the system, and then re charge the system with the proper type and quantity of refrigerant. Our photo at left shows that a Catch All C 1. S refrigerant dryer and filter has been installed on the high pressure refrigerant line leaving the outdoor compressorcondenser unit. This is where we usually see this device installed. Notice that the refrigerant dryer, which removes un wanted moisture from the refrigeration system, is labeled with the types of refrigerant with which it is designed to be used. Article Contents. Article discussion topics What is that grey canister you see at an air conditioning component why are driers and filters installed on refrigeration equipment When is a refrigerant gas drier usually installed Where should the refrigerant drier be installed on refrigeration equipment Special refrigerant drierfilter for use when a compressor motor has been replaced. Diagnosing a saturated or dirt clogged refrigerant drier canister How to fix air conditioning or refrigerator refrigerant gas leaks. Where is the Refrigerant Drier Located on HVAC Systems Carson Dunlop Associates sketch illustrates where the filterdryer is most often found at air conditioning or heat pump equipment on the liquid refrigerant line, in one or more of these locations outside, near the condenser unit see sketch at leftinside near the evaporator coil, ahead of the thermostatic expansion valve or capillary tubeat both of the above locations, and possibly even on the suction line on a system at which a burnt out compressor motor has been replaced. Most HVACR refrigerant filter driers are designed to be soldered in place, as is the unit shown at left. Some driers may permit connection using flare fittings a connection we consider less secure and more leak prone. When a refrigeration system is or has been open has been emptied of refrigerant for re charging, for example, the last repair step before re charging the repaired air conditioning or heat pump system with refrigerant is to install a filterdrier such as shown in our photo at left. The purpose of a refrigerant drier is to absorb and thus remove moisture in the refrigeration system. The effects of moisture on refrigeration systems are detailed at REFRIGERANT LEAK DETECTION but in sum we can say that moisture in the system can prevent proper operation and can even completely stop the system from working at all, even causing costly damage. We also find a drier installed on refrigeration systems that have been serviced for a refrigeration leak, especially a low side piping leak, because of the increased chance that the system has been contaminated by moisture and perhaps dirt. In fact if the system was open and badly contaminated the HVAC technician may install a drier right after the repair and may install a new or second drier on the same system a few months later. While some technicians always install a filterdrier on the refrigerant system, even at original installation, more often when we see a refrigerant drier canister on a system usually at the compressorcondenser unit we assume that the system has undergone some service or repair as thats most often when the device is added. Refrigerant Drier Filter Installation Positions Locations on HVACR Equipment. Where is the Drier Usually Located on an Air Conditioning, Heat Pump, or other Refrigeration System The drier is installed at the coolest location on the system, on the liquid line, outside of the refrigerated space, and ahead of any refrigerant metering devices like thermostatic expansion valves or capillary tubes. In our photo left you can see that the drier has been installed outdoors, at the point where the high side liquid refrigerant line is exiting the compressorcondenser unit. In our photo below left youll see a filterdrier installed in two locations on the air conditioning system compressorcondenser. Refrigerant filter drier canisters may also be installed indoors. Some air conditioner and heat pump installation instructions specify the installation of a liquid line filter drier indoors as well as or in place of outside at the compressor condenser unit. A typical indoor refrigerant filterdrier location is shown in our sketch at left see the blue canister with red arrow showing refrigerant direction flow in Carriers sketch at left edited. Braze 5 in. 1. 27 mm liquid tube to the indoor coil. Wrap filter drier with damp cloth. Braze filter drier to above 5 in. Flow. arrow must point towards indoor coil. Connect and braze liquid refrigerant tube to the filter drier. Watch out UNIT DAMAGE HAZARD. Failure to follow this caution may result in equipment damage. Installation of filter drier in liquid line is required. Source Carrier5Below our photo illustrates the installation of a refrigerant filterdrier at the A coil you can see the horizontal drier canister to the right of and protecting the tan colored Thermostatic Expansion Valve TEV. Refrigerant Filter Drier Applications, Installation Details, Warnings. A factory approved liquid line filter drier is required on every unit Always install the factory supplied liquid linefilter drier. If replacing the filter drier, refer to Product Data Digest. Obtain replacement filter driers fromyour distributor or branch. Carrier installation instructionsMatch the filterdrier to the operating pressure properties of the refrigerant gas and equipment on which it is to be installed. For example, on HVACR using Puron R4. A refrigerant, do not use liquid line filter driers with rated working pressures less than 6. Do not leave Puron suction line filter driers in line longer than 7. Use the correct type of filter drier for the location at which it is to be installed. Do not install a suction line filter drier in liquid line. Do not overheat or damage the filter drier during installation. For example installation instructions typically call for the filter drier to be wrapped in a wet cloth during brazing of its connections to the refrigerant tubing or piping. When air conditioner or heat pump refrigeration system must be opened for service, recover refrigerant, evacuate then break vacuum with dry nitrogen and replace filter driers. Evacuate to 5. 00 microns prior to recharging. Source PURONR R 4. Cracker Barrel Cheese Ireland.
