This
article will introduce air conditioning wall and window type (ie put the
machine in a hole like the window frame in the wall). These machines are
mainly used to reduce the temperature in the engine room or in the living room.
The
air conditioner is also an air conditioner, which also includes the engine
block, the compressor, the rigid rig, the rig and the capillary tube. This
machine is different from the fridge in the cooler to cool the air, and thanks
to the centrifugal fan the air in the room is cooled and then pushed back into
the room.
You want to buy an air conditioner but hesitate to choose which one to choose. Here are some guidelines that you need to know before deciding what to buy, or how to watch the machine to buy a good machine, used for a long time.
Air conditioners come in two types:

Air conditioners come in two types:
1.
Wall type (two-piece): This type has two separate parts made into two parts,
the cooler unit is installed in the house by mounting on the wall. The fan
and block are mounted outside the house, which is connected by a plastic tube
through a small pink hole (fitting the tube section) on the wall. This machine
is suitable for housing, corridors External (for placing fan and block).
Window
type (1 unit): This type is a homogeneous unit, which means that the fan unit
is always in the machine but not separated as the machine hanging
wall. This type is suitable for tall buildings. To mount this machine
just create a frame on the wall when mounting the machine, so that the surface
(cooler) back into the room.
In
general, the two types of machines work the same and buy the machine according
to the preferences of consumers.
To buy a good air conditioner, pay attention to the following:
Each air conditioner has a corresponding cooling capacity, meaning that each unit is only capable of regulating the temperature of the room.
The ability of the machine to cool (the ability to cool) is determined by its cooling capacity, ie the cooling capacity of the chiller is in a unit of time.

The ability of the machine to cool (the ability to cool) is determined by its cooling capacity, ie the cooling capacity of the chiller is in a unit of time.
The
larger the cooling capacity, the greater the cooling capacity.
The larger the capacity, the greater the cooling capacity (note the electrical power of the machine, not the cooling capacity). On the machine often specify the power consumption. Therefore, when there is no exact value of cooling capacity of the machine can be based on the estimated power capacity. Normally small scale air conditioners produce 75% of the electrical capacity of the machine.
The air conditioner maintains that heat in the room in accordance with the requirements of the room, so the main purpose of the machine is to serve people, can maintain the temperature in the room about 20 to 25oC (in the summer). Corresponding to that temperature, combined with appropriate humidity, humans will feel most comfortable.
Air conditioners for mainte- nance maintenance require that the mains air temperature is appropriate for the type of machine or appliance, and the temperature maintained is also subject to this requirement.
To maintain cool or cool in the room, the air conditioner must be able to remove the heat in the room. There are two types of heat: the heat generated in the room, such as the light bulb, the machine, etc., and the heat from the outside, because the outside temperature is higher than the room temperature.
a. Heat emanating from the room: The body always emits heat around itself. The amount of heat that is emitted depends on the intensity of the person's labor. The higher the level of heat, the greater the amount of heat.

For
example:
• In
the room there are 10 mechanic workers, the heat is twice as much as the heat
of 10 people working in the office.
In addition to the amount of heat emitted by the human body, the machine also emits a considerable amount of heat. For example: in the working room of a mechanic (welders, lathe workers, coolers, etc.), they usually arrange the machines corresponding to their work, or in the office work room. Electric motors, such as fans, bulbs, computers, printers, and fax machines emit a corresponding amount of heat.
b. Exterior heat: A room with air conditioning, the temperature in the room is always lower than the outside temperature. Therefore, when there is a difference in temperature, there is heat transfer from the outside to the room. The amount of heat transferred depends on the difference in temperature between the two environments. For example: the outside temperature is 35oC, inside the room is 15oC, the outside heat will infuse more, vice versa if the wall The thicker the room or the better the insulation, the lower the heat transfer.

Examples:
• Transmission through windows. If the door turns toward the sun, the amount of heat that passes through it is greater than the door does not turn toward the sun.
• Wall passage: If the wall is thicker and more insulating, the less heat it passes through. Heat can also be passed through doors or floors.
• Thus, when calculating the amount of heat entering the room, you have to calculate the area of the door (in, the window), the area of the partition walls, the floor area and should be calculated in the direction, the thickness of the wall ... and in turn deduce the amount of heat that can be transferred into the room.
• Finally, the total amount of heat emitted in the room and the amount of heat externally transmitted to the room. That is the basis for you to choose a suitable air conditioner for your room.
