Temperature recovery system for an electronic programmable thermostat
First Claim
1. A method of controlling an air conditioning system which comparises the steps of:
- calculating a recovery time peroid for said air conditioning system to bring the ambient temperature of the air within a predetermined volume of space from a first current temperature level to a second desire temperature level, said recovery time period being calculated as a function of the difference between the first current temperature level and the second desired temperature level;
continuously monitoring the ambient temperature of the air within said predetermined volume of space; and
controlling the rate at which said air conditioning system brings the ambient temperature to the desired temperature level during said recovery time period by providing said system with a switching logic which regulates the on/off switching of said air conditioning system in response to the amount of rise and fall of the ambient temperature and prevents said system from bringing the air within the predetermined volume of space to the desired temperature level until substantially the end of the recovery time peroid.

Abstract
A method of controlling a multistage heating system so as to minimize the energy required to bring the temperature of a predetermined volume of space to a predetermined temperature level is provided. The multistage heating system includes an energy efficient first heating mechanism and at least a less energy efficient second heating mechanism. First, a time period for the multistage heating system to bring the temperature of the predetermined volume of space to the predetermined temperature level is calculated. This calculated time period is provided into a plurality of zones, each of the plurality of zones having an associated temperature limit. The first and second heating mechanism are controlled in each of the plurality of zones according to a switching logic associated with each respective zone such that the temperature within each zone does not exceed the associated temperature limit.

5. A method of controlling a muli-stage air conditioning system having an energy efficient first stage and at least one less energy efficient second stage, said method comprising the steps of:
-
calculating a recovery time period for said multi-stage air conditioning system to bring the ambient temperature of a predetermined volume of space from a first current temperature level to a second desired temperature level, said recovery time period being calculated as a function of the difference between the first current temperature level and the second desired temperature level; continuously monitoring the ambient temperature within said predetermined volum of space; dividing said calculated recovery time period into a plurality of switching zones; providing each of said switching zones with an associated temperature limit; and controlling the rate at which said air conditioning system brings the ambient temperature from the first current level to the second desired level within said recovery time period by providing said system with a switching logic which regulates the on/off switching of said first and second stages of the air conditioning system in response to the amount of rise and fall of the ambient temperature within said associated temperature limits.

6. A recovery system for use in an air conditioning system to bring the ambient temperature of the air within a predetermined volume of space from a first current temperature level to a second desired temperature level, said recovery system comprising:
-
a thermostat; means for calculating a recovery time period during which said air conditioning system brings the ambient temperature of the predetermined volume of space from said first temperature level to said second temperature level, said recovery time period being calculated as a function of the difference between the first current temperature level and the second desired temperature level; means for continuously monitoring the current ambient temperature within said predetermined volume of space; and means for controlling the rate at which said air conditioning system brings the ambient temperature to the desired temperature level during said recovery time period by regulating the on/off switching of the air conditioning system in response to the amount of rise and fall of the ambient temperature. - View Dependent Claims (7, 8)
