# comfort-temperature

To calculate the comfort air temperature from the standard of ASHRAE-55

Core code comes from https://github.com/CenterForTheBuiltEnvironment/comfort_tool  

## Usage

`npm install comfort-temperature`

```js

var ct = require('comfort-temperature').ComportTemperature;

var ta = 15;    // air temperature, [C]

var tr = 25;    // mean radiant temperature, [C]

var vel = 0.8;  // air speed, [m/s]

var rh = 40;    // relative humidity, [%]

var met = 1;    // metabolic rate, [met]

var clo = 0.6;  // clothing level, [clo]

var wme = 0;    // external work, [met]

var result = ct.Calculate(ta, tr, vel, rh, met, clo, wme); 

console.log(result);

```

Output would be 

```js

{

  pmv: -4.558394498497179,

  ppd: 99.999999470295,

  set: 13.537207469450086,

  ta_adj: 8.775882545393353,

  tr_adj: 18.77588254539335,

  cooling_effect: 6.224117454606647,

  cat: 30

}

```  

The `cat: 30 °C` would be the suggested best **Comfortable Air Temperature**.

You can double check the result from this web tool: https://comfort.cbe.berkeley.edu/  

Put all parameters in the form, then change the **Air temperature** with the value of `cat`, you will see the `PMV with elevated air speed` is the lowest. Which means it's the best comfortable air temperature. https://en.wikipedia.org/wiki/Thermal_comfort#PMV/PPD_method
