A. Choose how capacity?

Choosing Chiller capacity is based on room structures such as wall covering, windows, towards the sun, ventilation and climate of each region. Power is called the electric power consumption of the refrigeration compressor unit is horse power (HP), for example 1HP ~ 9000 BTU / h (cooling capacity), 1.5HP ~ 12,000 BTU / h, 2HP ~ 18,000 BTU / h, 2.5HP ~ 24,000 BTU / h. In our experience, the structure houses in Vietnam today, you can choose 1HP capacity equivalent to the bedroom area of ​​14m2 - 16m2 or 12m2 living room area - 14m2. - Buy PC and purchased? Chiller plant often used for family apartments are 2-piece machines with indoor and outdoor wall hanging outdoor. Currently, the market has many types of machines are manufactured in Thailand, China, Malaysia, Taiwan, Vietnam, ... design quality and price are far different. Choose a Chiller is just beautiful, just reliable and suit your budget is that consumers think twice. When selecting a machine, in addition to quality, style and price, you need to consider after-sales service provider such as warranty, replacement parts, ... For sure, you should contact directly with the center or the distributor of the genuine, vending machines must be financial with the bill and its warranty. In recent times also appeared a few brands Chiller machine is assembled in Vietnam from the joint venture factory with high quality and competitive price.

Two. Why do you put it back to avoid wind?

When the Department has put in place the hot wind is blowing directly onto the surface of the machine will heat loss is occurring "in the wind". Heat escaping from the natural wind blowing back into the machine, making machine is not cooling and cause overheating, resulting in room temperature is not lowered and the machine is turned off frequently abnormal.

3. Note the installation:

General requirements

- The position must be fitted easily manipulated. If installed in a difficult position and must be equipped with wire scaffold insurance.
- Copper wire connection between the local hot and cold Department not be longer than 15 meters with a capacity for 9000BTU and 12000BTU.
- For machines with a capacity of 18000BTU, 20000BTU and 24000BTU copper wire connection between the local indoor hot with not more than 20m.
- The Department should not place too high hot indoor 7m for a capacity 9000BTU and 12000BTU, no more than 15m for a capacity of 18000BTU, 20000BTU and 24000BTU.
- Cables for sources with a capacity of ≥ 1.5 mm 9000BTU and 12000BTU
- Cables for sources with a capacity of 18,000 BTU ≥ 2.5 mm

Requirements for indoor mounting position

- Installation of indoor wall was solid and balanced to prevent vibration.
- And the airflow unobstructed to gas that can be released all over the room.
- Do not install indoor where direct sunlight projector on.
- Installation in indoor places can be connected with a local hot outside easiest way.
- Installation of indoor where drainage pipes can be installed easily and air filters can be removed for maintenance, cleaning regularly.
- Road Department in cold water to steep.

Requirements for local heating installation location

- If possible, do not mount local hot spots have direct sunlight on the projector.
- Do not install in places with hot local strong wind or debris.
- Do not place hot department where many people pass by.
- Do not place directly in the hot department.
- Note the direction of a neighbor’s house that might be blowing hot air from the Department on windows or noise.
- Space to transient local heating, the distance between two walls with gable and rear heated to ≥ 30 cm gantry
- The distance to the local hot wall opposite to ≥ 60 cm

Actions fitted

- Use size Balance Divo taken to place coil bracket, the sign and the screw holes.
- When the drill holes and how much to trace punch is smooth and slightly sloping outwards, the lower edge of the hole is not lower than the bottom edge of the coil. Coil bracket must be securely bolted to the wall.
- Measure the distance from the coil to the hot rig.
- Cut the copper pipe wrap insulation, wire machines.
- Acting as co jack: Marking wire in order to match coil, so that the jack operation has
not crack.
- Always have the pipe through the hole perforated copper coil to hang on racks.
- Pin or hang copper pipe firmly into the wall.
- Drilling rig rack hot
- Set local warming rack, proceed to squeeze the connector can push hot rig, then expel air discharge coil and strangled in jack available to the gable.
- The tip of the order marked in cooler, tape rolling and open terminal.

Requirements

- Pipe installation must meet the aesthetic requirements. If his water line tube when the tube pins to the slope.
- First there must be tight connectors.
- Hot Hangers Department must ensure certainty and safety.

Run machine

- Check to see if water drains flowing in coil or not, if there is water running down your drain is normal operation.
- Check the hot and cooler view rigs operate smoothly or not.
- Use a clock to measure steady ampere of current.
- Use a pressure gauge to measure pressure at the top of the rig back on heating according to the prescribed standards.

4. "Oil trap" is what? Why have oil traps?

Some cases are not fitted due to the location should be convenient to local hot or roof terrace ... are generally higher than indoor locations. In this case, if workers do not have experience handling only a few days after installation of the machine may be damagedBecause the Department of rusty hot gas and lubricating oil, the running, gas oil evaporation also run vertically and deposited much of the tube in cold Department makes no cold machine, block machine, while the lack of lubrication. Experienced workers will make an oil cap (oil trap), by bending the U-tube to prevent oil falling cold Department, local fire hot block for lack of lubrication.
