Heat and Cool Capacity Test, Real Time EER Measurement

Warmth Cool Systems can be tried to gauge continuous BTU Capacity and EER. It isn’t unexpected to locate a 3 ton, 13 SEER, Heat Cool System just delivering 2 tons and 8 SEER. We have discovered new establishments with this issue. heat pump vs ac

On the off chance that the framework is more than 12 years of age it might have lost critical limit and effectiveness.

About 70% of your warmth and cool climate control system unit limit is utilized to bring down the temperature of the air. The excess 30% limit is utilized to eliminate mugginess or dampness from the air. As an illustration a 3 ton unit ought to have an all out 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 eliminate dampness from the air. To gauge all out limit, we should quantify both.

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 main gracefully vent. On the off chance that you duplicate the distinction in temperature by 1.08 btu for each cubic foot of wind stream delivered by the Heat Cool System, you have the limit measure that brings down the temperature. This measure is called reasonable warmth.

Another thermometer called a psychrometer or hygrometer is expected to gauge the stickiness that is taken out by the climate control system. A psychrometer is a typical thermometer with a wet cotton sock over the bulb. The temperature perusing called wet bulb temperature can be changed over to a worth demonstrating the temperature and grains of dampness noticeable all around. This worth is called inert warmth and enthalpy. You can buy or make a wet bulb thermometer. An exact advanced hygrometer that estimates % relative stickiness can be bought for around $100. Utilizing an enthalpy outline or enthalpy number cruncher accessible on the web, you can change your estimations over to btu’s. It is imperative to quantify wet bulb temperature inside one 10th of a degree F.

The more troublesome measure to get 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 gauge static weight. Guidance recordings for estimating wind current in CFM can be found on

The Formula

Computing all out Btu’s includes estimating wind stream and wet bulb air temperatures in and into an adapted space. All out Btu’s are determined utilizing the equation:

Absolute 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 absolute flexibly wind stream entering the structure from the framework.

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

Inert eat = Total Heat – Sensible Heat


Air and warmth can spill into the framework between your temperature readings and the indoor cooling loop. On the off chance that this occurs, your figuring will demonstrate the cooling conveyed to the space and not the cooling delivered by the AC unit.
