Warmth Cool Systems can be tried to gauge continuous BTU Capacity and EER. It is basic to discover a 3 ton, 13 SEER, Heat Cool System just creating 2 tons and 8 SEER. We have discovered new establishments with this issue.
On the off chance that the framework is more than 12 years of age it might have lost huge limit and effectiveness.
Around 70% of your warmth and cool aeration and cooling system unit limit is utilized to bring down the temperature of the air. The staying 30% limit is utilized to expel dampness or dampness from the air. For instance a 3 ton unit ought to have an aggregate limit of 12000 btu’s for each ton or 36000 btu’s. Of the 36000 btu’s, 24000 btu’s would bring down the temperature of the air and 12000 btu’s would expel dampness from the air. With a specific end goal to quantify add up to limit, we should gauge both. Air Conditioning
A typical thermometer will gauge the air temperature entering the arrival of your AC and the temperature of the colder air can be estimated at the principal supply vent. On the off chance that you duplicate the distinction in temperature by 1.08 btu for each cubic foot of wind current delivered by the Heat Cool System, you have the limit measure that brings down the temperature. This measure is called sensible warmth.
Another thermometer called a psychrometer or hygrometer is expected to gauge the mugginess that is expelled by the aeration and cooling system. A psychrometer is an ordinary thermometer with a wet cotton sock over the knob. The temperature perusing called wet globule temperature can be changed over to an esteem demonstrating the temperature and grains of dampness noticeable all around. This esteem is called dormant warmth and enthalpy. You can buy or make a wet globule thermometer. An exceptionally precise computerized hygrometer that measures % relative dampness can be acquired for around $100. Utilizing an enthalpy outline or enthalpy number cruncher accessible on the web, you can change over your estimations to btu’s. It is critical to gauge wet knob temperature inside one tenth of a degree F.
The more troublesome measure to acquire is the measure of wind current in cubic feet every moment (CFM). An instrument called a vane anemometer can be utilized as can an instrument to quantify static weight. Guideline recordings for estimating wind stream in CFM can be found on www.youtube.com
Ascertaining all out Btu’s includes estimating wind current and wet globule air temperatures in and into an adapted space. Add up to Btu’s are ascertained utilizing the equation:
Add up to Btu = 4.5 X CFM X Enthalpy Change
The 4.5 factor speaks to the heaviness of 1 cubic foot/minute (CFM) of standard air every hour.
CFM is the aggregate supply wind current entering the working from the framework.
Enthalpy change is estimated utilizing a hygrometer and changing over the readings to Enthalpy.
Inert eat = Total Heat – Sensible Heat
Air and warmth can spill into the framework between your temperature readings and the indoor cooling curl. In the event that this happens, your figuring will demonstrate the cooling conveyed to the space and not the cooling created by the AC unit.
You can likewise decide hardware wind stream via painstakingly estimating fan static weight, at that point plotting the fan CFM in light of the producer’s fan information
An enthalpy change of around 6 is typical.
Wind stream majorly affects framework execution. It must be estimated precisely with top quality instruments and systems.
A mugginess level of 90% or more from the supply side of the framework is normal. As the air is cooled is can hold less dampness.
