Abstract
According to an aspect of the present disclosure, there is disclosed a method of determining the use of hot water performed in a system including a water heater and an air handler. The method includes: sensing a temperature of influent flowing into the water heater; sensing a temperature of effluent flowing out of the air handler; calculating a temperature difference between the temperature of the influent and the temperature of the effluent; and determining whether hot water is used by calculating whether the temperature difference is greater than a predetermined value.
Claims9
A method of determining the use of hot water performed in a system including a water heater and an air handler, the method comprising:
- sensing a temperature of influent flowing into the water heater;
- sensing a temperature of effluent flowing out of the air handler;
- calculating a temperature difference between the temperature of the influent and the temperature of the effluent;
- and
- determining whether hot water is used by calculating whether the temperature difference is greater than a predetermined value.
A hot water usage determining system comprising:
- a water heater;
- a first temperature sensor configured to sense a temperature of influent flowing into the water heater;
- an air handler configured to receive heating water from the water heater for heating and to discharge effluent after heat exchange;
- a second temperature sensor configured to sense a temperature of the effluent, and
- a controller communicable with the first temperature sensor and the second temperature sensor;
- wherein the controller calculates a temperature difference between the sensed temperature of the influent and the sensed temperature of the effluent, and determines whether hot water is used by calculating whether the calculated temperature difference is greater than a predetermined value.
