2.7 Refrigerant Condition
This part of the Energy Efficiency Manual presents energy conservation measures that maintain the correct conditions of the refrigerants in your chillers, air conditioners, and heat pumps. Managing the refrigerant of your cooling equipment is important routine maintenance. Neglecting it will cause a serious drop in efficiency and cooling capacity. You need to maintain the proper level of refrigerant, neither too little nor too much. You also need to make sure that nothing enters the cooling system but refrigerant.
The methods you learn here apply to both compression cooling and absorption cooling, and they apply to cooling units of all sizes. These Measures also reduce expensive equipment failure, and they extend equipment life. Maintaining efficiency and avoiding equipment damage are closely related aspects of refrigerant management, especially with low-pressure refrigerants.
