Abstract
In accordance with embodiments, there are provided techniques for operating an HVAC to provide substantially contemporaneous thermal feedback in response to a user varying a temperature set point of the system. This is achieved using an HVAC system of the type having a pump in fluid communication with both a supply of gas and a duct system, having an input and an output and defining a flow path therebetween, and a temperature regulation system in thermal communication with the flow path. A controller is in electrical communication with the temperature regulation system and the pump to regulate operation of the HVAC system.
Claims20
A method of operating an HVAC system having a pump in fluid communication with both a supply of gas and a duct system, having an input and an output and defining a flow path therebetween, a temperature regulation system in thermal communication with said flow path and a controller in electrical communication with said temperature regulation system and said pump, said method comprising:
- receiving a request from said control system to varying a temperature of said gas exiting said output;
- establishing, with said controller, operation of said pump to maximize a flow rate of said gas propagating through said output into a volume for a first duration of time;
- upon expiration of said first duration of time establishing operation of said pump, with said controller, to reduce the flow rate of said gas exiting through said output into said volume to a desired flow rate that is less than said maximum flow rate, with said first duration of time being independent of a temperature of said gas in said volume;
- sensing a temperature of said gas in said volume using said controller;
- and
- terminating gas flow through said output in response to said controller sensing said gas in said volume has reached a desired temperature.
A method of operating an HVAC system having a pump in fluid communication with both a supply of gas and a duct system, having an input and an output and defining a flow path therebetween, a temperature regulation system in thermal communication with said flow path and a controller in electrical communication with said temperature regulation system and said pump, said method comprising:
- receiving a request from said control system to establish in said volume a desired set point temperature;
- transmitting, with said controller, a temperature control signal to cause said temperature regulation system to vary a temperature of gas propagating toward said output to a pre-determined temperature set point that is different from said desired set point temperature, with said pre-determined temperature being independent of the magnitude of the desired set point temperature;
- and
- upon expiration of a pre-determined duration of time, establishing said temperature regulation system to transmit with said controller a regulation signal to said temperature regulation system to establish said gas exiting said output to maintain a temperature in said volume proximate to said desired temperature set point.
An HVAC system for regulating the atmosphere of a volume, said system comprising:
- a duct system having an input and an output, defining a flow path therebetween;
- a supply of gas in fluid communication with said duct system;
- a pump in fluid communication with said duct system;
- a temperature regulation system in thermal communication with said flow path;
- and
- a controller in electrical communication with said temperature regulation system and said pump, with said controller having a processor and computer readable memory in data communication with said processor storing instructions when operated on by aid processor to cause said controller to establish operation of said pump to maximize a flow rate of said gas propagating through said output into a volume for a first duration of time in response to receiving a request to varying a temperature of said gas exiting said output;
- upon expiration of said first duration of time establish operation of said pump, with said controller, to reduce the flow rate of said gas exiting through said output into said volume to a desired flow rate that is less than said maximum flow rate, with said first duration of time being independent of a temperature of said gas in said volume;
- sense a temperature of said gas in said volume using said controller;
- and terminate gas flow through said output in response to said controller sensing said gas in said volume has reached a desired temperature.
