Split System at a Garment Showroom1. SummaryPower Knot’s distributor in India, Protronix Energy, working with Kool Nest Pvt Ltd treated a packaged unit air conditioner with the Power Knot Synthetic Refrigerant Additive at Freedom Garments Showroom in Bangalore.After treatment, the system was operating quieter and more efficiently. This was a proof of concept (POC) that impressed the experienced technicians at Kool Nest and demonstrated real benefits of the Synthetic Refrigerant Additive (SRA).
2. Introduction 2.1 The ProblemThe system selected for the POC was a system from Blue Star. Blue Star has, over a period of time, established itself as an expert in the field of central air conditioning and commercial refrigeration. This a/c system had been in service for nine years and the customer wanted to reduce energy consumption. 2.2 The Solution Power Knot guarantees a minimum of 10% savings after the application of the SRA. In the case of Freedom, this will mean the treatment will pay for itself within nine months. 3. About the Cooling EquipmentThe details of the a/c system are listed in figure 3.
4. Test ProcedureThis was a prof of concept. As such, Protronix Energy decided not to monitor power for a week in advance. Instead, we measured current consumption of the system and the temperature of the air fed to the store.
Prior to treatment, we measured the key parameters of the system as listed in figure 4. Although the measured parameters seem to indicate there is to much subcool, we proceeded to treat the system.
The system was treated SRA and then the measurements of power and ventilation temperature were made again. 5 Improvements After TreatmentThe first thing we noticed is that the compressor noise decreased immediately. We then recorded that the power consumption had decreased and the temperature of the air coming out of the supply duct also decreased. The recordings are listed in figure 5.
6. CreditsPower Knot would like to thank the management and staff of Freedom for their purchase order placed with Protronix Energy. We are also grateful to Mr. Charles Godfrey, Director, and technicians Sunil Melvin and Shameel at Kool Nest who assisted with this POC.7. ConclusionThrough the application of the SRA, Power Knot guarantees a gain in the efficiency of a refrigeration system of at least 10%. This study has shown that treatment has improved the operating efficiency of the system. The payback period for this customer for the treatment of the a/c system is approximately nine months.
