Window air conditioners are one of the most commonly used and cheapest type of air conditioners. To install one of these units, you need the space to make a slot in the wall, and there should also be some open space behind the wall.
The human body feels comfortable at certain values of temperature, relative humidity and velocity of air inside a room. These are called comfort conditions or comfort zone. They depend on a number of factors, which the HVAC designers should be aware of.
The human body is like a machine that consumes fuel and produces power and heat. When the body consumes food, which contains lots of calories, it gets converted partially into energy and partially into heat. To attain body comfort, the excess heat generated inside the body should be removed.
AutoCAD is one of the most popular CAD software programs. Autodesk has launched the latest version named AutoCAD 2009. It has great looks and a number of additional features, which have been discussed in this article.
CAD stands for Computer aided designing or drafting. CAD software has become an inseparable part of the engineers and architects involved in designing, drafting and manufacturing. This article discusses what CAD is, its applications and some popular CAD software.
A number of software programs have come on the market that make complex HVAC design and heat load calculations very simple. Here one such product named AutoCAD HVAC Design software is described.
Heat is generated inside the room from various sources. Some of these include heat gained by the walls, heat entering from the windows, heat generated by the people, electrical equipments etc.
The HVAC system selected haphazardly for your home or office can turn out to be insufficient or highly expensive. For achieving comfortable conditions at optimum costs, HVAC design for your home or office is important.
Air conditioning is the process of maintaining comfortable conditions inside a closed space. It controls temperature, humidity, air flow rate and the cleanliness of air inside a room.
There are four important parts of a refrigerator: compressor, condenser, expansion valve and evaporator. Freon gas passes through all these parts continuously in the form of a cycle and undergoes various phase and temperature and pressure transformations. Freon acts as the media for transfer of heat.
The process of refrigeration is used for many day-to-day applications. It is used to chill water, make ice and ice cream, keep your food fresh and a host of other purposes. Let us try to know the basics of the refrigeration process.
Mechanical Engineering is one of the widest fields of engineering. It includes various fields like manufacturing processes, automobiles, thermal & hydraulic power plants, refrigerators & air-conditioners, aeroplanes, rockets, cryogenics, and much more.
