Class hvac

java.lang.Object
  |
  +--hvac

public class hvac

extends java.lang.Object

Describes the characteristics of a HVAC system, and provides related mtehods.

Constructor Summary

hvac(double hcop, double ccop, double th, double tc, Utility heating_util, Utility cooling_util)
Creates an instance of the hvac class, given the COP of the heating system, the COP of the cooling system, the heating set temperature, the cooling set temperature, a Utility object representing the source of heating energy, a Utility object representing the source of cooling energy.

Method Summary

double	getCoolingCOP() Returns the current Coefficient of Performance for cooling.
double	getCoolingCost(double kwh) Returns the cost (in dollars) of energy used in cooling, based on costs in the current Utility object and the current type of heat, given the heating requirement, in kilowatt hours.
double	getCoolingTemp() Gets the current thermostat setting (in C) for cooling.
Utility	getCoolingUtil() Returns the current cooling Utility object.
double	getHeatingCOP() Returns the current Coefficient of Performance for heating.
double	getHeatingCost(double kwh) Returns the cost (in dollars) of energy used in heating, based on costs in the current Utility object and the current type of heat, given the heating requirement, in kilowatt hours.
double	getHeatingTemp() Gets the current thermostat setting (in C) for heating.
Utility	getHeatingUtil() Returns the current heating Utility object.
void	setCoolingCOP(double cop) Sets the current Coefficient of Performance for cooling.
void	setCoolingTemp(int tc) Sets the current thermostat for cooling.
void	setCoolingUtil(Utility util) Sets the current cooling Utility object.
void	setHeatingCOP(double cop) Sets the current Coefficient of Performance for Heating.
void	setHeatingTemp(int th) Sets the current thermostat for heating.
