NISCO Fan Co. has offered a few techniques of effective building ventilation and cooling. In industrial plants where there is a high density of employees and many manual operations involved, an improvement in the environment can produce substantial benefits in terms of increased production, reduced errors, and a decline in complaints and absenteeism among employees. In other circumstances, the attentiveness of an audience or student group may be a factor that spells success or failure for the project. To obtain a reasonable degree of personnel comfort in hot weather, there are three basic...

Potable buildings are nothing more than modular buildings that can also be defined as built to serve units. You will find that portable buildings are quickly becoming a popular choice for many people around the world. In fact portable homes have already caught on in Australia, Britain and America. Here are some the most frequently asked questions about Portable buildings. What are portable buildings? Portable buildings are pre fabricated structures made in a factory. The building is then transported to the required location and installed by trained professionals. The biggest advantage of...

Insultec, heat reflective paint when applied to roofing areas lowers the inside temperature of buildings, which means less use of electricity to run cooling systems which in turn will contribute to the reduction in global warming. A win, win situation for everyone. Developed in Australia this unique composite, forms a membrane which is capable of re-radiating 90% of infrared and 85% of ultra violet rays back into the atmosphere. Temperature readings on the underside areas of roofing not treated with the heat reflective paint were recorded at 55.8oC whereas areas under the same roof at the sam...

What is HVACR? The "Heating-Ventilation-Air Conditioning-Refrigeration"(HVACR) industry manages indoor environments. The HVACR industry covers the comfort systems - heating, ventilation, air conditioning and refrigeration - that our society depends on year around. The heating and cooling industry is a $150 billion a year business that employs many people and more skilled people are needed to fill the increasing demand. The HVACR industry works on issues that affect our environment such as indoor air quality and protecting the earth's ozone layer through refrigerant recovery. Where do...

Tenderall Fan Co. enginners truly reversible (exhaust and supply roof fan for general ventilating. The Type CBRE recirculators are designed for use in commercial and industrial applications where there is sufiicient ceiling height to create a temperature differential between the floor and the ceiling. These applications include factories, warehouses and large commercial buildings. CBRE Roof Recirculators function as regular power roof ventilators in warmer weather and as an energy-saving recirculation air system in cold weather. Each unit is equipped with a reversible fan that dist...

Greenhouse Ventilation Fluid ventilation within a greenhouse is possible because of a combination of roof vents, side vents and (of course) the inside/outside door. When constructing (or purchasing) a greenhouse, airflow within the greenhouse is, by far, one of the most important aspects to consider. Low-level ventilation is essential if you are trying to produce plants with dense foliage at ground level (tomatoes for example). The heat levels must be consistent as well as airflow from the fans. You must avoid stagnant air inside your greenhouse at all costs, as it will undoubtedly bring...

The idea that if you build a playhouse in the garden for your kids, it may improve the value of your property might sound outrageous, but at the very least it will increase the saleability of your home.

Many kinds of extras in a property can often clinch the deal for an undecided buyer. If two homes have the same appeal, but one has a small garden shed with a nice big window ove...

The UK has one of the oldest and least efficient building stocks in Europe, accounting for nearly half of the UK’s carbon emissions. If you overlay this statistic with the new Government target to reduce CO emissions by 80% by 2050, it is clear that direct action must be taken to reduce the emissions from buildings. This article focuses on commercial buildings, which are a clear target for such action and new measures have been recently introduced which target new buildings and for the first time, the stock of existing buildings. Energy Performance Certificates (EPCs) came into force on...

The combustion process in the engine generates huge amounts of heat. Hence, an efficient cooling system is needed to avoid overheating and its harmful effects. The cooling system is composed of various components that help in maintaining the engine’s normal operating temperature. The radiator is the main player in the cooling system, but another important component is the expansion tank. Connected to the radiator through the expansion tank hose, the expansion tank is sometimes called the overflow tank, coolant reservoir, or overflow canister. The expansion tank is a plastic container used...

In sweltering hot summers, the cool breeze from the air conditioners becomes a welcome respite that helps in rejuvenating from the heat. However, in order to maintain the perfect cooling conditions of the home and office it is very necessary to maintain the air conditioning filters in their optimum conditions. If the air conditioner has poor filters, it will cause inflated electricity bills. This can cause double burden on the user as both the air conditioner as well as the electricity bills will cause trouble. Thus it is very important to have proper air conditioning filters. It is ...
