Zeolite Molecular Sieves Drying Refrigerant / Refrigeration
The life of most refrigeration systems depends on when the refrigerant leaks. The leakage of refrigerant is caused by the reaction of the refrigerant and the trace water contained in it, which results in the corrosion of the pipeline. Molecular sieve of Dalian Haixin has the characteristics of low dew point, high strength and low wear, and has good compatibility with the refrigerant, and does not ...

EPA mandates proper refrigerant gas recovery processes
New EPA regulations require facilities that use air conditioning and refrigeration equipment to have a refrigerant recovery plan in place. The plan is needed to make sure that any harmful gases that might leak are captured. Refrigerant gases contain hydrochlorofluorocarbons, known to cause severe damage to the ozone layer and to promote global warming. A comprehensive plan is now in place to ...

Refrigerant leak creates environmental problems for businesses
A great concern for companies is a refrigerant leak in their refrigeration and air-conditioning (RAC) system or heating, ventilation and air conditioning (HVAC) system. That’s because gases that escape during a refrigerant leak pollute and damage the environment. To better monitor and maintain the operation of these business assets, many companies utilize a refrigerant management program.There ...

Understanding the CARB Refrigerant Gas Management regulations (2010 early actions)
Many of today's AC/HVAC systems and refrigerant products have high global warming (GWP) potential emissions. These include air conditioning (AC) in cars, homes and office buildings, commercial and home refrigerators, fire suppressant systems, and much more. Many of today's AC/HVAC systems and refrigerant products have high global warming (GWP) potential emissions. These include air conditioning ...

Applying Refrigerant Codes
Administering limits for the amount of refrigerant that can be discharged into a space in the event of a leak Some years ago, two young and inexperienced technicians were called to work on a large refrigerant system. The system was not working properly because of an incorrectly installed valve. In their attempt to fix the system, the technicians caused a leak in the piping at the tank, which ...

Exergy analysis of hydrocarbons mixture refrigerants R436A and R436B as a drop in replacement for R134a with TiO
2nanoparticlesThe refrigerator exergy efficiency (EE) with nanoparticles in the working fluid was investigated experimentally. Mineral oil (MO) with TiO2 nanoparticles mixtures were used as the lubricant instead of Polyol ester (POE) oil in the R134a, R436A (R290/R600a–56/44–weight %) and R436B (R290/R600a–52/48–weight %) refrigerator. The results indicate that R134a, R436A and R436B and MO with TiO2 ...

Global Warming Potential (GWP) significance of HCFC refrigerant gases
The global warming potential of chemicals is well documented. This is usually documented by referencing how much a chemical will impact global warming as compared to a similar amount of carbon dioxide. Refrigerants typically outrank carbon dioxide by a factor of 100 or even 1000 and stay in the atmosphere longer to our climate's detriment. All greenhouse gases are allocated a global warming ...

Refrigerant leak detection is regulated by the US Environmental Protection Agency (EPA)
Refrigerant leak detection is a difficult task in some heating ventilation and air conditioning systems or refrigeration and air conditioning systems. Sometimes the most experienced technicians find difficulty discovering a leak, which may be hidden in a system component, in tubing or in an operating or safety control switch. Refrigerant leak detection is a hot topic, following the recently ...

Heavy refrigerators are turning easily with the fridge turner
New handling system for refrigerator degassing ATN receives more and more requests from customers (especially from outside Europe) for automatic handling systems. Refrigerators are becoming bigger and heavier. In countries like the USA the weight of a refrigerator can be well over 150kg. In order to avoid manual handling of these big refrigerators during the degassing process ATN developed an ...

Reasons Why Monitoring Restaurant Refrigerators and Freezers is Important
Restaurants typically have refrigerator and freezer facilities for storing perishables. Larger restaurants and kitchens in hotels for example, have larger commercial type refrigerators. Whatever the size, monitoring restaurant refrigerators and freezers is important. In this article we will examine some of the reasons why remote monitoring of commercial refrigerators in restaurants is ...

Degassing Refrigerators - Drill-head and Piercing-plier
1. For what purpose do we have to degas a refrigerator? A refrigerator has to be disposed as hazardous waste. The refrigerants inside a hazardous refrigerator are harmful for the environment (ozone depleting and greenhouse effect). Most common refrigerants are; R12, R134a and R600a. The uncommon is the removal of NH3. Refrigerants are developed to dissolve very easily into the compressor oil. ...

Exergy based refrigerant selection and simulation of auto refrigeration cascade (ARC) system
This paper deals with the selection of refrigerants and simulation of Auto Refrigeration Cascade (ARC) system, which is generally used for low temperature applications in the range of -40 to -150°C that operates with zeotropic mixture, containing two or more refrigerants with different boiling points. The selection of refrigerants depends on the working pressure and temperature range of ...

California Air Resources Board (CARB) places higher restrictions on air pollution
As part of the California Global Warming Solutions Act (AB 32) the Air Resources Board (ARB) has approved an early action measure to reduce high-global warming potential (GWP) greenhouse gas (GHGs) emissions by establishing new legislation and defining requirements related to improved monitoring of AC/HVAC systems, enforcement of regulations, reporting of refrigerant usage, and recovery, ...

Realistic limitations to the operation of heat-driven refrigerators
The optimal characteristic curve relating the COP and the refrigeration rate of an irreversible heat-driven refrigerator is established on the basis of a thermodynamic model which combines the endoreversible model and the heat leak insulation model. It is found that the curve is loop-shaped and that both the refrigeration rate and the COP exhibit a maximum. In addition, it is shown that the curve ...

What is a ton of refrigeration?
Commercial refrigeration systems in the US are mostly rated in tons of refrigeration and this term is used widely in other parts of the world. However, outside the US, cooling systems may be normally specified in kW (or MW) or in Btu/h. The roots for refrigeration are in the ice making industry, and the ice manufacturers wanted an easy way of understanding the size of a refrigeration system in ...

Medical Refrigerator Disposable Temperature Data Logger Manufacturer
Medical refrigerators can refrigerate and remain stable and constant, so they are suitable for storing medicines and some medical supplies. Since many drugs are sensitive to temperature, higher temperatures will affect the quality and effectiveness of the drugs, so they are placed in medical refrigerators to keep the temperature constant and appropriate. Disposable Temperature Data Logger can be ...

Refrigerant leak detection is heavily regulated by government agencies
Refrigerant leak monitoring in refrigeration and air-conditioning (RAC) systems and heating, ventilation and air conditioning (HVAC-R) equipment is very challenging, even for the most skilled HVAC-R technician. The leak could be well concealed from view in tubing, a system component, or in an operating or safety control component. With the Environmental Protection Agency (EPA) laws ...
