Ultra-low temperature storage is an essential part of the medical cold chain and can save you from wasting expensive products. It can also help you keep your inventory frozen until it’s ready for distribution or sale.

Biological samples such as blood and plasma are stored in freezers to ensure they are properly preserved and that there is always a supply of life-saving blood available. Keeping these samples at -18oC or below prevents bacteria and microorganisms from growing and spoiling the product.


Refrigerant is a chemical compound that is used to make air conditioning systems and refrigerators function. It can be confusing, but it’s important to understand how it works if you want to keep your home cool and comfortable in the summer.

Refrigerants are classified into different groups based on how they transfer heat from one part of a system to another. They can be liquid, gas, or a combination of both.

Class 1 refrigerants cool by absorbing heat energy, lap dat kho lanh thuc pham nha hang usually through a process called vapor compression. They include refrigerants such as air, calcium chloride brine, sodium chloride brine, and alcohol.

There are also many types of liquefied refrigerants, which can be classified as either Class 2 or Class 3. The Class 2 refrigerants cool by absorbing the heat energy of a nonfreezing solution.

In addition to refrigerants, there are also a variety of other substances that can be used for cooling. Some examples include water, alcohol, and ice.

The most commonly used type of refrigerant in the United States is hydrofluorocarbon (HFC), which is a type of halogenated polyfluoroalkyl substance that contains fluorine, chlorine, and carbon. It was phased out in the 1990s for contributing to greenhouse gas emissions.

Air Quality Control

Air quality control is the process of managing the emission, transport and transformation of pollutants within the atmosphere. It involves all levels of government, regulated industries and scientists.

Various techniques can be used to control pollutants, including absorption, adsorption and incineration (combustion). These processes are effective against gaseous criteria pollutants, as well as volatile organic compounds and other air toxics.

Particulate matter with aerodynamic diameters of 2.5 microns and less is the most common form of air pollution in North America, and is particularly dangerous to asthmatic sufferers. High concentrations can cause inflammation and lung damage.

The United States Environmental Protection Agency maintains an air quality monitoring network that includes over 10,000 ambient monitors and over 5,000 monitors that are active. Data from these monitors is consolidated and stored in the EPA’s Air Quality System.

An AQS-derived daily Air Quality Index (AQI) is a measure of the pollutant concentration in the ambient air for the day. It indicates whether or not the air is considered to be clean and healthy for most people.

A non-attainment area is a region that has air quality that does not meet the National Ambient Air Quality Standards (NAAQS). It must have and implement an action plan to reach NAAQS compliance or lose some forms of federal financial assistance, such as grant programs for projects that improve air quality in the area.

Backup Power

Battery backup systems (also known as uninterruptible power supplies, or UPS) provide instantaneous power to plugged-in devices when main power is interrupted. They can be used in a variety of applications, including computers, office equipment, and mobile devices such as smartphones and tablets.

Backup power systems can range from small single cells to battery room facilities that support the uninterruptible power supply of large data centers. These can be powered by generators, but today’s cleaner energy systems, such as solar panels, wind turbines, and biogas facilities, also offer a reliable source of backup power.

In the United States alone, there are over 100,000 backup power systems in use. These units represent both new and replacement systems for supporting computer systems, telecom systems, and other applications.

A fuel cell system for backup power applications has significantly different requirements than those for automotive and stationary (primary) power generation markets. In general, fuel cell systems designed for backup power are much lighter than conventional batteries.

This weight advantage may not matter as much for most stationary applications, but for some locations it could improve the competitiveness of a fuel cell system compared to traditional backup batteries. Additionally, the hydrogen storage of a fuel cell backup power system must be sufficient to operate for the period required. This hydrogen can be stored in empty hydrogen bottles, or can be generated via an electrolyzer.
