Refrigerant Management: Checking and Recharging for Optimal Cooling

two person fixing the aircon

Air conditioning is now a necessity in most homes throughout the year. However, to ensure optimal cooling, it is essential to manage refrigerants properly. Over time, refrigerant leaks may occur, resulting in inefficient cooling and potential equipment damage. In this article, we will delve into the art of refrigerant management, covering checks and recharging, to maintain the ideal cooling performance in your air conditioning system.

Signs of Refrigerant Leak

One of the most common indicators of a refrigerant leak is when the air conditioning unit is not running as efficiently as it should. You may also notice cooler temperatures produced by the condenser fan than normal. Another sign is the presence of ice on the coils or an oily residue leaking from the equipment. If you observe any of these signs, it may be an indication that your system requires recharging.

Checking Refrigerant Levels

Before adding refrigerant, it is crucial to determine if it is necessary. The first step is to check either the superheat or subcooling numbers, depending on the type of unit. Superheat refers to the amount of heat a refrigerant absorbs after it is converted into a gas. On the other hand, subcooling measures the amount of cooling that occurs after the refrigerant condenses from a gas to a liquid. Both superheat and subcooling numbers can be obtained from the equipment manufacturer or regulatory bodies in your region.

The Importance of Metering Device Check

Metering devices, such as expansion valves, are prone to failure and incorrect installation. By measuring the superheat, which remains relatively constant under different operating conditions, you can assess whether the metering device is functioning properly. Additionally, measuring the saturation pressure and comparing it to the pressure table for the specific refrigerant can provide a better understanding of its state.

Effects of Overcharging and Undercharging

Overcharging your air conditioning system can lead to low superheat temperature and high subcooling temperature. This imbalance increases the risk of liquid refrigerant finding its way back to the compressor, potentially causing compressor failure.

On the other hand, an undercharged system can result in low subcooling temperatures and excessive noise caused by vapor bubbles in the liquid line. An undercharged unit may also exhibit reduced cooling capacity and inefficiency.
