What size ducted air conditioner Do I need calculator?
The rule of thumb calculation is to multiply the total daytime living area by the ceiling height. Naturally, you’ll find that a house with higher ceilings requires an air conditioner with a larger capacity because air conditioning is all about the volume of air that needs to be cooled or heated.
What are the requirements of comfort AC?
Humans generally feel comfortable between temperatures of 22 °C to 27 °C and a relative humidity of 40% to 60%. first cool the air to 14 °C (this removes some of the water from the air), and then heat the air to 24 °C. the heat and mass of water removed in the cooling phase, and the heat added in the heating phase.
What is air conditioner rated capacity?
The required cooling capacity for a room air conditioner depends on the size of the room being cooled — room air conditioners generally have cooling capacities that range from 5,500 Btu per hour to 14,000 Btu per hour. A common rating term for air conditioning size is the “ton,” which is 12,000 Btu per hour.
What is nominal capacity of air conditioner?
Nominal capacity refers to the capacity of the air conditioner that manufacturers claim their product has, when they are selling it. This is also known as nameplate capacity. This is the number that you will find on your product or one that a sales manager will use while telling you the AC capacity and features.
How many kW Do I need air conditioner?
For a room 10m2 to 20m2, a 2.6kW unit should cool the room; For a room 20m2 to 30m2, a 3.5kW unit should cool the room; For a room 30m2 to 45m2, a 5-6kW unit should cool the room; and. For a room 45m2 to 65m2, a 7-8kW unit should cool the room.
How do you calculate kW to cool a room?
- Simply multiply the (L) length by the (W) width.
- 4m x 3m = 12m.
- Then : 12m x 140 Watts = 1680 watts.
- We need 1680 Watts minimum to cool this room.
- 2000W or 2.0 KW is perfect.
- Anything less than 1680 Watts will not cool this room.
How many kW does a ducted air conditioner use?
Therefore, you can assume the unit is only cooling intermittently at an average capacity of around 6kW. Assuming a modest usage of around 80 hours per quarter, the system uses 480kW of electricity a quarter.
What are the four conditions of air conditioning?
An air-conditioning system must be effective regardless of outside climatic conditions and involves control over four fundamental variables: air temperature, humidity, movement and quality.
How do you read AC specs?
Find the model number. Within this string of letters and numerals, you should find an even, two-digit number. The possibilities on residential units range from 18 to 60. Divide the number by 12 (which represents 12,000 Btu/hr, or one ton of cooling capacity) to get your AC unit’s tonnage.
How do you calculate nominal capacity?
Nominal Capacity This is the volume of the tank when filled to the brim. Calculated by multiplying the length x width x height e.g. 3m x 2m x 2m = a nominal capacity 12,000 litres.
What area does a 5kW air conditioner cover?
20 to 35 sqm
Generally speaking, a 5kW air conditioner will cool between a 20 to 35 sqm size room. However, there are a number of factors that may affect this, such as which way your windows are facing and whether or not your ceiling is insulated.
What size room will a 7kw air conditioner cool?
For a room 20m2 to 30m2, a 3.5kW unit should cool the room; For a room 30m2 to 45m2, a 5-6kW unit should cool the room; and. For a room 45m2 to 65m2, a 7-8kW unit should cool the room.
How many kW of cooling do I need?
Generally speaking, you’ll need roughly about 0.15 kilowatts per square metre. For example, a smaller room that measures 20 square metres would need an air con around 3kW, while a 60 square metre room would need a device capable of delivering around 9kW.
How do you calculate aircon kW?
Most air conditioning units are measured in kilowatts (kw), not watts – luckily, it’s pretty easy to convert between them – just move the decimal point 3 places to the left to get the kW value. For example, 100m² x 150 watts = 15,000 watts, which equals 15 kilowatts – for this room, you’ll need a 15kW split system.
