There are ways of how to recharge air conditioner systems. The methods for this air conditioning maintenance are,refrigerant charging from high pressure side,refrigerant charging from low pressure side,and refrigerant charging using weight Here are some extra tips for you before venturing into how to recharge air conditioner.purpose of refrigerant charging is to add or remove, a specified amount of refrigerant from an air conditioning system, such that you will get comfort air from the air conditioner.contrary to popular belief, refrigerant do not require periodical charging. It is not a consumable item within an air conditioning unit, unless,there is a leak within the system,you have just changed an air conditioner part, ORyou are assembling a brand new air conditioner unitrefrigerant of 4xx series, e.g. R-404a are non azeotrope type refrigerants, EXCEPT for R-410.R-410 is a near azeotrope mixture.So, what’s the big deal between azeotrope and non azeotrope refrigerant?Azeotrope refrigerants consist of more than one blend of refrigerants, but it acts like a single refrigerant.

Non azeotrope refrigerants on the other hand, DO NOT act like a single refrigerant.The implication is that, the blends will be lost from the system at different proportions due to different boiling temperatures, whenever there is a leakage in the non azeotrope refrigerant.Hence, charging of non azeotrope refrigerant can only be carried out from zero to full. Never top up this type of refrigerant in case of leakage.Evacuate, and fill to adequate quantity.Azeotrope, or near azeotrope blends will act as a single refrigerant, and therefore, may be topped up in case of refrigerant leakagedo not overcharge as this will cause compressor damage,do not underchargecorrect problems within the system, if subcooling or superheat is inadequate, even if the pressure in the system has reached design statenever use open flame to heat up refrigerant cylinders. heil ac unit warrantyUse warm water insteadrecover the excess refrigerant into recovery cylinder, if the system is overchargedA little more before we go further into how to recharge air conditioner systems.happy gilmore ac unit

the amount of refrigerant superheat is about 10 oF (5.5 oC), or as per manufacturer’s recommendation, ORthe amount of refrigerant subcooling is about 10 oF (5.5 oC), or as per manufacturer’s recommendation, ORthe sight glass after (or on) the filter dryer is clear after charging.Presence of bubbles means that there is no adequate chargingIt’s about time we look into details of "How to Recharge Air Conditioner". How to recharge air conditioner style 1: From high side:lg air conditioner parts brisbane This method is best used with capillary tube fitted systems.Other criteria that will require this technique are inadequate subcooling, and to top up refrigerant.First,stop the compressor,know the refrigerant in the system, and get the correct refrigerant to be charged,attach the refrigerant cylinder or canister to the centre manifold’s hose of the pressure gauge set,purge the line by throttling the plain gauge’s regulator, and the refrigerant cylinder’s regulator.

Don’t forget to close the regulators after purging,attach plain pressure gauge’s hose of the gauge set, to the liquid line service valve of the air conditioning unit.Make sure that the protective cap of the service valve is taken outopen the plain gauge’s regulator slightly,throttle the refrigerant cylinder’s regulator,close the cylinder’s regulator when the pressure in the high pressure side reaches the design operating pressure,operate the air conditioning unit,check the subcooling, and make sure that the is clear,stop the air conditioning unit if the subcooling is inadequate. Repeat steps (7) to (10) until the charging is adequateCourtesy for condenser picture: Bryant Air Conditioners How to recharge air conditioner style 2: From low side: This method is with thermostatic expansion valve fitted systems.Other criteria that will require this technique are inadequate superheat, and to top up refrigerant.First,stop the compressor,know the refrigerant in the system, and get the correct refrigerant to be charged,attach the refrigerant cylinder or canister to the centre manifold’s hose of the pressure gauge set,purge the line by throttling the compound gauge’s regulator, and the refrigerant cylinder’s regulator.

Don’t forget to close the regulators after purging,attach compound pressure gauge’s hose of the gauge set, to the suction service valve of the air conditioning unit.Make sure that the protective cap of the service valve is taken outopen the compound gauge’s regulator slightly,throttle the refrigerant cylinder’s regulator.The pressure within the system shall be less than the condensing pressure of the refrigerantoperate the air conditioning unit,close the cylinder’s regulator when the pressure in the low pressure side reaches the design operating pressure,the charge should be adequate once the design pressure on the low side is reached, but it is good to check the superheat, and make sure that the sight glass is clearCourtesy for condenser picture: Bryant Air Conditioners How to recharge air conditioner style 3: Using weight: This method is used to charge refrigerant to an evacuated, or newly assembled, and moisture removed air conditioning unit.The steps,stop the compressor,know the refrigerant to be handled by the system, and get the correct refrigerant to be charged,attach the refrigerant cylinder or canister to the centre manifold’s hose of the pressure gauge set,purge the line by throttling the compound gauge’s regulator, and the refrigerant cylinder’s regulator.

Make sure that the protective cap of the service valve is taken output the cylinder on weighing scale,ORget adequate number of refrigerant canisters to charge the system open the compound gauge’s regulator slightly,throttle the refrigerant cylinder’s regulator,operate the air conditioning unit,close the cylinder’s regulator when the correct amount of refrigerant is added to the systemcheck the superheat, operating pressure, and make sure that the is clearCourtesy for condenser picture: Bryant Air ConditionersThat’s about it on how to recharge air conditioner systems. Remember that a leak free system do not need regular refrigerant charging.Top of How to Recharge Air Conditioner page Back to Air Conditioning MaintenanceYour window unit could make you sick. Before you install a window air conditioner in a room, consider some of the harmful effects it can have. Mold, for example, can be worse in a window unit than a central AC system. Other possible problems apply to air conditioning in general, not just window units.

Respiratory Illness Window unit air conditioners work by drawing heat and humidity from the room to lower the ambient temperature. The dehumidifying effects can also cause some drying of the mucus-coated lining inside your nose and allow airborne viruses to enter your system. A study published by the International Epidemiological Association in 2004 found higher sickness rates attributed to upper respiratory illnesses in women working in air-conditioned offices as opposed to women working in offices without air conditioning, though results were considered preliminary, due to limitations of the study's data. Allergy Irritant The humidity the window air conditioner draws from the air doesn't magically disappear; it deposits on the cooling coils inside the unit. This moisture plus dust creates an attractive environment for mold-growing spores. Failing to remove and clean or cover the window unit during the winter allows the accumulation of mold inside the cabinet. Neglecting to clean the filters inside the unit or installing inferior filters can allow dust and debris to pass through it.

Breathing these mold spores can trigger allergy symptoms, such as coughing, watery eyes and a runny nose. Mold can also trigger breathing restrictions in asthma sufferers. Inspect and clean the coils as needed. Outdoor Air Infiltration A high-quality window air conditioner that's properly installed should not permit unfiltered outdoor air into the interior space. However, any breach in the seal between the air conditioner unit and the window can introduce outdoor air, along with allergens and other air pollutants. Additionally, a malfunctioning or poorly designed air conditioner may not filter outdoor air sufficiently, pulling outdoor air directly into the room. To prevent these problems, make sure the air conditioner unit is fully sealed around the window opening and the unit is designed to filter all conditioned air. Also be sure to use a high-quality filter or supplemental disposable filter in addition to the unit's standard filter, to remove as many air pollutants as possible. Irritate Exiting Eye Conditions The allergens blown into the air by your window unit air conditioner can worsen allergic conjunctivitis, also known as Pink Eye.

An inferior filter allows dust mites and animal dander to pass through the window unit’s blower and pollute the air. These allergens irritate the lining of the eye, turning it pink or red. Air conditioning can also increase the suffering of individuals diagnosed with blepharitis. The cold air blowing into the room can accelerate tear evaporation and aggravate sufferers’ dry eye symptoms. Environmental Hazards Both window unit air conditioners and central units use refrigerant to cool your room. Depending on the age of the unit, it could use chlorofluorocarbon cooling agents that could leak from the sealed system and damage the earth’s ozone. Improper disposal of these older units could result in fines up to $25,000 issued by the Environmental Protection Agency. Even units using hydrochlorofluorocarbon cooling agents can harm the environment, although not as damaging as those units using chlorofluorocarbons. Check with your municipality for disposal facilities before you throw away your leaky unit.
