Quiet Operation: Despite its powerful capabilities, the PentaCare V12 operates quietly, with sound levels measured at43 dBAwhen tested at 250 CFM. This is comparable to less than the hum of a refrigerator, making it an excellent choice for residential use. You can enjoy a peaceful and comfort...
If you select "Airflow/Code", input a total airflow value (CFM or L/s) of outside air entering the house through the furnace or blower. This value may or may not be used to calculate the total ventilation cooling and heating loads, depending upon the option selected next. Ventilation...

For a house between 3000 to 4000 square feet with 2 to 4 bedrooms, your ventilation should be big enough to handle 80CFM airflow. The airflow value increases with your house's size and the number of bedrooms. →Download Now: HVAC Plan Examples & Templates PDF HVAC Plan Complete Guide...
350 CFM per ton of cooling capacityis required for high-latent-heat HVAC applications. (A latent heat cooling system is one that uses a cooling media that changes state - for example refrigerant that changes state between a liquid and a gas form). ...
The return air inlet collars 152, 154, 156 can be sized for an associated zone airflow requirement (e.g., CFM requirement). The return air section 72 can be configured such that the return air inlet collars 152, 154, 156 and the supply airflow inlet collar 164 are easily installable ...
These values are based on the building type, which determines the SF/ton value and the CFM/SF value and the total building area (SF). Figure 16: The first output is the total cooling load which is in terms of tons of cooling and airflow. You should use the building type discussion...
Along with the standard operating conditions, conditions for airflow and coil temperatures and operating range have also been established. Most if not all manufacturers design these grades of equipment for a nominal 400 CFM airflow per ton for A/C cooling, and 450 CFM/ton for heat pumps....
例如,以400立方英尺/分钟(或立方英尺每分钟(CFM))的空气供应的1000平方英尺的房间具有24 ACH(400×60/1000 = 24)。此风量(400 CFM)可能会小于满足室内制冷要求所需的风量。 Methods to determine airflow (in ft3/minute or m3/hour)are discussed in ISPE Good Practice Guide: Heating, Ventilation, and Ai...
For example, a conference room or hallway can have a box rated for 2000 CFM, while a small office can have a box rated for 150 CFM. Therefore, a damper in a higher capacity rated VAV box has a higher influence on the downstream pressure sensed by the static pressure controller. The ...
