Huu Phat Electrical Engineering Co., Ltd is the contractor for construction of the following systems:
Local air conditioning system
Central air conditioning system VRV
Central air conditioning system CHILLER
Ventilation systems for buildings and buildings
Stair pressure system.
Storage system for factories and supermarkets
Huu Phat also designs and advises the investor on investment solutions and selects the most suitable equipment suitable for each type of works.
According to the function, operating mode and requirements of the microclimate environment, the air conditioning system of the buildings is designed as a total solution, capable of creating the appropriate microclimate environment. For each area of the building, meeting the common standards in the world. From that point of view, the air conditioning system for the building is designed to ensure the following basic criteria:
1. Ensure the temperature, humidity, air purity of the building in accordance with human comfort standards in all weather conditions. Room temperature and humidity can be set and maintained at different levels depending on the user's requirements.
2. Clean air supplied by the air-conditioning system ensures a minimum level of 20 ¸ 30m3 / h.
3. The air in the building is well ventilated with the purpose of avoiding phenomena such as air from the toilets, spreading to other places or outside hot and humid air. The phenomenon of dew in the room.
4. The air-conditioning system is capable of automatically adjusting the actual thermal capacity of the building from time to time in order to improve the efficiency of the system and to save operating costs.
5. The equipment of the system is highly reliable, simple operation and convenient for maintenance and repair.
6. The whole system is designed, installed without affecting the interior and architecture of the works. System noise does not affect areas of the building and surrounding areas.
SOME TYPES OF MODIFIED AIR CONDITIONING SYSTEMS IN VIETNAM:
1) Air-cooled packaged (Air Conditioners)
a / Air Conditioner:
* Window Conditioner (Window):
- Advantages:
Simple assembly.
- Disadvantages:
Structural structure is distorted because many air conditioning units surround the house.
Dependent on outside temperature: High outside temperature is reduced or power may stop for some time.
Low efficiency, no power savings.
Low reliability and durability (compared to the central compressor type compressors, the life expectancy is only 1/10).
Limited operating range, less efficient.
* Split air conditioner:
The feature is similar to a window air conditioner.
It does not deform the structure of windows, but has the disadvantage of not getting fresh air (oxygen-rich air).
b / V.R.V (Valueable Refrigeration Volume):
- Advantages:
Very convenient to install for high rise buildings, an outdoor unit mounted on the roof can be installed 8 or even 16 air conditioners (Indoor Unit)
Power saving.
- Disadvantages:
Compared with other systems, the cost of the V.R.V system is relatively high.
Capacity is limited, so for buildings with large heat load, many V.R.V systems must be installed
Because the outdoor unit is cooled by air, the outside temperature affects the power.
Corrective maintenance.
2) Water cooled packaged air conditioners:
- Advantages:
Cooling capacity is stable thanks to cooling system is water coolant.
- Disadvantages:
Fitting for tall buildings is limited because the fan head blowing through the indoor unit is low, the flow is small, the wind pipe occupies a lot of space should be forced to fan.
3) Water chiller + Fan coil units:
- Advantages:
The cooling capacity is very stable thanks to the cooling system is water.
Cooling goes to water-filled rooms, so pipelines can slip into the Pipe shafts so it does not affect the aesthetics of the building.
The type of air cooled chiller is suitable for placing on the roof of high buildings.
Water coolers are installed in the basement.
