along with the economic and social development, the central air-conditioning is becoming increasingly popular, both in the shopping malls, supermarkets, office buildings such as commercial places, or in villas, penthouse floor apartment, this kind of housing, we can see the figure of central air conditioning. In addition to the host, the central air conditioning of the terminal equipment is also a large proportion of the part, the following article for you to introduce the central air conditioning terminal equipment selection considerations. Choice of terminal equipment of
central air conditioning equipment selection of air conditioning box

before selecting the air conditioning box according to the central air-conditioning system load to determine the amount of wind, wind pressure, cold heat, air outlet noise and air filter requirements, specific attention should be paid to the following points:

1. thermal insulation layer box should be not less than 0.68 square meters of · K/W, the current use of PEF material or polyurethane foam.

2. table cooler head wind speed control in the 2-2.5m/s.

The static state

3. combined type air conditioning cabinet is 700Pa, the machine leakage rate shall not exceed 3%, but the air leakage rate as high as 10% of the phenomenon in practical use. In order to avoid this kind of situation, it is better to request the sealing material property and the box body rigidity. The general air conditioning panel materials preferred the appearance of spray plate,mobile evaporative air cooler, if the glass steel material should pay attention to the fire.

fan coil

 

central air conditioning terminal equipment selection considerations - fan coil selection

we judge the fan coil pipe is good or bad, mainly to see the wind, cold, noise, power consumption of these indicators, the choice should pay attention to the following:

Fan coil

1. domestic market most manufacturers only three rows of tubes, few can provide two of the discharge pipe, the air flow in the cold under the premise of equal amount is larger, is helpful to improve the accuracy of air conditioning and comfort, so you can choose a priority two pipe fan coil.

2. state of the fan coil, cold air and noise parameters to test in static pressure outside the machine is 0, so the actual use of air volume is less than the test parameters, thus reducing the comfort of air conditioning, so we should give priority to more pressure in the selection of the unit (10-15Pa).

3. noise problem is the focus of domestic fan coil complaint, is large compared with the imported products where the cause of this problem is because the motorfan configuration is not reasonable, so we have to refer to manufacturer noise test report issued by the authority of the state quality inspection departments in the selection, in addition should also consult. The test report and other related documents to ensure product quality detection.

above for the introduction of the central air conditioning terminal equipment selection considerations for reference only, the actual choice is to be analyzed according to the specific circumstances. The central air-conditioning has always been three product, seven installation ", selected the appropriate equipment and auxiliary material, then the design and installation of more heavy.
