Warmth Cool Systems can be tried to quantify continuous BTU Capacity and EER. It is regular 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.

In the event that the framework is more than 12 years of age it might have lost critical limit and productivity.

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 every 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. Keeping in mind the end goal to quantify add up to limit, we should gauge both. Furnace Repair 

A typical thermometer will quantify the air temperature entering the arrival of your AC and the temperature of the colder air can be estimated at the main supply vent. On the off chance that you duplicate the distinction in temperature by 1.08 btu for each cubic foot of wind current created 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 quantify the dampness that is evacuated 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 inert warmth and enthalpy. You can buy or make a wet globule thermometer. An extremely precise advanced hygrometer that measures % relative mugginess can be obtained for around $100. Utilizing an enthalpy graph or enthalpy adding machine accessible on the web, you can change over your estimations to btu’s. It is vital to quantify wet knob temperature inside one tenth of a degree F.

The more troublesome measure to acquire is the measure of wind stream in cubic feet every moment (CFM). An instrument called a vane anemometer can be utilized as can an instrument to gauge static weight. Guideline recordings for estimating wind stream in CFM can be found on

The Formula

Figuring all out Btu’s includes estimating wind stream and wet knob air temperatures in and into a molded space. Add up to Btu’s are figured utilizing the recipe:

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 stream entering the working from the framework.

Enthalpy change is estimated utilizing a hygrometer and changing over the readings to Enthalpy.

Dormant eat = Total Heat – Sensible Heat


Air and warmth can spill into the framework between your temperature readings and the indoor cooling loop. In the event that this happens, your count will demonstrate the cooling conveyed to the space and not the cooling delivered by the AC unit.

You can likewise decide hardware wind current via painstakingly estimating fan static weight, at that point plotting the fan CFM in view of the maker’s fan information

An enthalpy change of around 6 is ordinary.

Wind current majorly affects framework execution. It must be estimated precisely with top quality instruments and methods.

A moistness level of 90% or more from the supply side of the framework is normal. As the air is cooled is can hold less dampness.
