The combined air -conditioning unit is a kind of air treatment equipment assembled from various air treatment functions.Suitable for air -conditioning systems with resistance greater than 100Pa.The air treatment function section of the crew has air mixed, balanced, filtering, cooling, primary and secondary heating, de -dampness, humidification, gauges, refuses, water spraying, sound dispellation, heat recovery and other units.
Combined air -conditioning unit brand
At present, well -known brands in China are: Aiko, Robate, and Wes currently three brands have production bases in China: Ecarobat currently has factories in Germany and Thailand.The price can basically be the same in China; Wes is currently only produced in Germany, so the price is also the highest among the three brands.Zhuo Bang has heard that it is also good. The new combined air -conditioning unit of Zhuo Bang has adopted the advanced modular box structure. The unique internal framework and thermal insulation panel design ensure the low energy consumption defense knot of the box of the box to the maximum extent.Delite performance.
Combined air -conditioning unit installation
Basic precautions for installation of combined air -conditioning units: First, after buying the equipment they need, the operator checks according to the combined air -conditioning unit equipment table and related ordering lists. GenerallyThe name and specifications of the air -conditioning units and the specifications. The second, related air -conditioning models, specifications, etc. can be disassembled after verifying, and then start checking the technical parameters of the air -conditioning unit equipment.Third, for the installation project of multi -system combined air -conditioning units, the system must be installed one by one. In addition, it should also be confirmed by the construction site manager before the formal assembly procedure can be performed.Fourth, the relevant assembly sequence of each functional section of the combined air -conditioning unit must meet the prescribed design requirements.If there are errors, the process of air treatment and air treatment may be poor.
Combined air -conditioning unit selection
Precautions for selection of combined air-conditioning units: 1. Box insulation; in order to prevent the box of the box from exposed, the national standard stipulates that the thermal resistance of the box insulation layer should not be less than 0.68m-2/kW.The cold bridge generated at the point.Thermal insulation materials are mostly used in PEF or polyurethane.At present, many manufacturers have invented the segment connection of various patented structure boxes to block the cold bridge and prevent leakage.2. Wind -faced wind speed: In order to save costs and reduce the shape size of the box, some manufacturers often make the air -conditioning box greater wind speed.Unreasonable, then this problem is even more serious.Therefore, when selection, we should control the wind speed of the cooler at 2 to 2.5m/s.
Principles of combined air conditioning units
The combined air conditioning unit is divided into single -cold air conditioners and cooling and cold dual -use air conditioners. The working principle is the same. The refrigerant mostly used in the air conditioner before is Flun.Freons characteristics are: when it changes from gaseous to liquid, a lot of calories are released.When changing from liquid to gaseous, it will absorb a lot of heat.(That is, first absorb thermal vaginification and liquefaction) The air conditioner is designed according to this principle.The compressor compressed the refrigerant of the gaseous to high -temperature and high -pressure gaseous refrigerant, and then sent it to the condenser (outdoor machine) to dissipate the heat and become a liquid refrigerant with room temperature and high pressure, so the outdoor unit blows the hot air.Then go to the capillary tube and enter the evaporator (indoor machine). As the refrigerant suddenly increases the space after reaching the evaporator from the capillary tube, the pressure decreases, and the refrigerant of the liquid will vaporize and become a low -temperature refrigerant, thereby absorbing a large amountIn heat, the evaporator will become cold. The fan of the indoor machine will blow the indoor air from the evaporator, so the indoor machine blows out the cold wind; the water steam in the air will condense into a water drop after the cold evaporator encounters a cold evaporator., Follow the water pipes, which is why the air conditioner will get out of the water.When heating, there is a component called the four -pass valve, which makes the refrigerant opposite the flow direction of the condenser and the evaporator during the cooling. Therefore, the cold wind is blowing outdoors when heating, and the indoor machine blows hot wind.In fact, when the liquefaction (from gas to liquid) in junior high school physics (from gas to liquid), the principle of heat and vaporization (from liquid to gas) must be discharged.
