Simple and fast calculation method of positive pressure air volumeĪ good sealed clean room, in the use of the process, the main air leakage way has the following four: Is there a faster and easier way for engineers who build clean rooms?Ĭalculation method of differential pressure in clean room
#Room volume calculator manuals
However, in various design manuals about clean room, the calculation of the positive pressure in clean room lists the complex calculation process. In clean room design, the first thing designers face when planning drawings is the calculation of the positive and negative pressure air supply in clean room. This way the inverter AC is heavy-duty and energy-efficient compared to the non-inverter technology.A simple and rapid method for calculating the positive pressure air volume in clean room In the Inverter AC, the compressor works to reach the preset temperature of the thermostat but after that slows down to maintain the cool airflow. It dehumidifies the air in monsoon and prevents it from getting damp. The dehumidifier system controls the humidity in the air and allows clean air circulation within the room. It is necessary to enjoy a healthy cooling environment. Invest in the AC with air filters that inhibit dust particles, pollen, and other contaminants to maintain a Clean AC and quality airflow. It is always recommended to buy a 5 stars AC and if not at least 3 stars, to save your pocket on high rates of power tariffs.īuy the Air Conditioning system that works on an auto-cleaning mode and remove the allergic deposits within the blower. Here, energy efficiency means the capacity to save on energy consumption and hence the power bills. It’s one of the qualifying factors we look up to before buying any electronic appliance. Let’s understand the method to calculate the estimated AC tonnage for a given room area.Įxample 1: Length= 12 feet long, Width= 10 feet wideĮxample 2: Length= 12 feet long, Width= 10 feet wide, Ceiling Height = 24 feet high
Hence, selecting the right AC with the standard BTU capacity is foremost. Whereas, if it’s low then the room will not cool effectively.

If the BTU capacity is high for the given room size, it will fail to maintain the humidity levels making your skin feel clammy and sticky. Now, why is it important to understand the BTU chart while selecting the room AC? In simple terms, the amount of heat converted into cool air by an Air Conditioner in a given time period is known as BTU. The cooling capacity of an AC is calculated in British Thermal Units (BTU). Once you calculate the room area, know the cooling capacity of AC required.
Calculating Room Area and Understanding the AC Cooling Capacityīefore buying an Air Conditioner, apart from looking towards the different AC technology and brands, you need to calculate the size of the room and measure the space to choose the best AC based on the cooling capacity.
