Air-Conditioners
October 28, 2007
Air conditioner is a well designed mechanism to extract heat from and area using refrigeration cycle. HVAC (High Voltage Alternating Current) is a complete air conditioning system of heating and ventilation.
It is a system that provides comforts in the living spaces, improves productivities in the factories and maintains constant and optimum temperature. It is able to lower the air temperature and the humidity level of the place.
The options may include room air conditioner, central air conditioner or heat pump. It is better to spend time in selecting the best system that suits your needs. The heat pump is able to provide winter heating, whereas the central air conditioners are cooling product only. Heat pump costs higher than the other.
If you plan to shift your home then it is better you look for room air conditioner which can move with you and re-installed in the new residence. In bungalows with incomplete cellar, a duct system may be comparatively uncomplicated and reasonably priced.
There are two options for central systems usually expensive and frequently impractical. Mini-slit unit uses two-three indoors connecting a single outdoor to distribute cooling. Systems with a small diameter high pressure ducts are used to facilitate retrofit installation through walls.
You can find two types of air conditioning such as room air conditioner and central air conditioner but they also have different kinds within each type.
Room air conditioners have types of window mounting, wall-mounted and free-standing portable units. In same way the central air conditioners have single-package with roof mounting, split-system consists indoor to outdoor section, mini-split and mini-duct system.
A Comforting Home Appliance
October 27, 2007
Air conditioning is referred to as High-Voltage Alternating Current which is abbreviated in to HVAC. Air conditioner with the support of refrigeration cycle extracts heat from your living room or office. This mechanism is especially designed to make your living room more comfortable. In offices and computer server rooms air conditioner maintains constant and optimum temperatures.
The technology behind the conditioner
New designed models are provided with ‘heat pump’ technology, benefiting to both consumer and the environment.
This technology based mechanisms are space saving and more energy-efficient. This system works as a fridge does, as it can both cool and heat buildings. This system achieves efficiencies between 300% and 500%.
Different options for Air Conditioner are available in the markets such as ‘Heat Pump’ Technology, ‘floor standing’, ‘ceiling or wall mounting’ unit, and Slip air conditioning systems. These different types of model will have different functions. So, to select the best one that suits your needs can be tricky.
To have maximum flexibility over programs of the system and room temperatures, buy an air conditioner with remote control.
Terms often used in air conditioning system
- Air to air ‘heat pump’ or ‘cooling unit’: A fan which connects the duct work for cooling and heating the indoor atmosphere and another fan which rejects heat to the external atmosphere.
- Air cooled chillers: An externally located compressor or condenser. Frozen water is got from these chillers.
- Air to water heat pump: This comes with a reversing valve and hot water as well as chilled water.
- Water to water chillers: Instead of air water is used to reject heat. The circuit which rejects the water is condenser water. It is provided by a cooling tower.
- Defrost circuits: In this the external coil freezes with ice even at low temperatures when heat pump extracts heat from external atmosphere.
Generally air conditioning system consists of filter, fan and cooling or heating coils. Heat pump unit is an outdoor unit which provides heating and cooling. It is associated with direct equipment expansion incorporated with coil, reversing valve, compressor and fan.
Room air conditioners for your comfort
October 19, 2007
Room air conditioners are, as the name refers to, an air conditioner that is
used to cool either a room or a limited area. These work on electric power by
removing the heat from the room and by conveying it outside through its vents.
It is not a big unit in comparison to the centralized units which require both
space and duct work for its installation. This room air conditioner is meant
to give comfortable refrigeration and you can have complete access over it when
the room is in use or not.
With its compact design it can be carried easily from one place to another. These
room air conditioners are mainly categorized into two - units with louvered
sides that can be mounted on a window or units without louvered sides that can
be installed through wall installation.
It works with the simple technology; the way that our refrigerators work. By absorbing
the heat and unwanted moisture from the room and conveying it to outside the room.
A fan inside the air conditioner when on work circulates the room air and brings
it in contact with the low pressure refrigerant inside the air conditioner. When
the air comes in contact with it, it gets cooled and this air is passed on to
the room again. Thus by the continuous proceeds of air circulation the room is
cooled.
Usually the room air conditioners are not so big but its size can be varied with
the change in the room size. It is again taken into consideration by the use,
for what type of room its used, how many people will be occupying it and for how
long. The climatic conditions too will be considered and thus with the expertise
of a contractor the size and capacity of the air conditioner is decided. The main
purpose in all the cases is the cooling of the room and it has to meet at any
cost. It can be chosen as per your requirement and is available in different models
to suit your convenience, either the window mounted or through the wall units.
Once installed keep the unit open and make sure its vents are not closed or hidden
or blocked with any furniture or drapes as it will effect its efficiency. Consult
the right person and get it done the way it has to be and keep yourself cool all
through the year.
