MEP_Engine: Add HVAC Total, Sensible, Latent Heat Equations

[travispotterBH]

Description:

Include calculations for total, sensible, and latent heat equations for airside.

Expected behavior: User input of the critical inputs for each equation, output is a heat value (Q)

Total Heat:
Inputs: Airflow (volumetric flow rate per min ) , State 1 Enthalpy, State 2 Enthalpy, Average density of two state points, or leave blank and default value for standard temperature and pressure.
Equation: Qt = volumetric flow rate * density * 60min/h * delta enthalpy of the two state points

Sensible Heat:
Inputs: Airflow (volumetric flow rate per min), state 1 temperature, state 2 temperature, average density of two state points, average specific heat capacity of two points
Equation: Qs= volumetric flow rate * specific heat capacity * density * 60min/h * delta temperature of the two state points

Latent Heat:
Inputs: Airflow(volumetric flow rate per min), state 1humidity ratio lbw/lbda, state 2 humidity ratio lbw/lbda, average density of two state points,
Equation: Ql = latent heat of vaporization of water * density of air * 60min/h * specific heat of water * volumetric flow rate * delta humidity ratio of the two state points.
