Barriers to Energy Conservation in Industrial Refrigeration
- Maine's Noble Success. Marcotte, Robert M.; Greim, Clifton W. // Engineered Systems;Mar2003, Vol. 20 Issue 3, p44
Focuses on the heating, ventilation and air conditioning systems installed in Noble High School in North Berwick, Maine. Functionality of the temperature control system; Energy consumption; Capability to provide sufficient temperature to the school facilities.
- Wise consumption. // Refrigerated Transporter;Jul2008, Vol. 44 Issue 2, p34
The article focuses on the use of the cost-effective efficiency measures for the refrigeration systems in reducing electric costs. With the rising energy costs, facilities are encouraged to implement the simple steps of refrigeration controls for them to lower their electrical consumption and...
- I Scream, You Scream. Elovitz, Kenneth M. // Heating/Piping/Air Conditioning Engineering;Jan2007, Vol. 79 Issue 1, p13
The article discusses the author's experiences in managing the temperature of his refrigerant. He described the pressure and temperature of his refrigerant. He offered information on the heat-balance calculations of his refrigerant, including its temperature capacity. He also explained how he...
- Electronic Expansion Valves. Dern, Charles D. // ASHRAE Journal;Mar2005, Vol. 47 Issue 3, p88
The mechanical thermostatic expansion valve (TXV) for many years has been a mainstay in refrigeration systems. Current valves control by a combination of springs, refrigerant pressure, and proprietary charges in capillary tubes. These valves perform well for systems that work in relatively...
- 3 Energy- Saving Strategies for Freezers. Melvin, Pat // Process Cooling & Equipment;Sep2006, p34
The article provides three energy-saving strategies for freezers. The head pressure control can be eliminated to allow a lower head pressure and condensing temperature in specifying electric expansion valve. Defrost should only be done when the coils need to be cleaned rather than defrosting...
- VARIABLE-SPEED Drives. McKew, Amanda // Engineered Systems;Mar2003, Vol. 20 Issue 3, p42
Presents a design checklist for a heating, ventilation and air conditioning (HVAC) system. Specification for the sequence of HVAC operations; Information on the functions of control devices; Energy consumption of the equipment.
- Excalibur brings down energy. // Meat Trades Journal;8/17/2012, p10
The article informs that Excalibur LPA Ltd., a chiller company, has joined hands with processing business to reduce energy consumption by 30 percent and increase refrigeration capacity to chill chicken.
- Energy management systems. Dunay, Ed; Story, George // Refrigeration Service & Contracting;Nov96, Vol. 64 Issue 11, p16
Presents a question and answer on the Energy Management Systems (EMS) used to control energy costs for refrigeration systems. Skepticism over the savings produced by a popular control scheme; Operation of an unloaded compressor; Oil return.
- Cooling solutions times two. // ACR News: Air Conditioning & Refrigeration News;May2014 Supplement The Green Issue, p11
The article discusses two solutions including the R22 refrigeration phase out and free cooling that businesses can employ to become more energy efficient across the board to save money and make the most of the natural ambient temperatures around them.
