Automatic HVAC control system

Abstract

An automatic HVAC control system is configured to control an HVAC unit, and the HVAC unit includes a heating mode and a cooling mode for modifying an air temperature of an inside space. The control system includes: a first temperature sensor disposed to measure an air temperature of an outside space; a second temperature sensor disposed to measure the air temperature of the inside space; a memory for storing a set-point for the HVAC unit; a set-point controller that adjusts the set-point based on the air temperature of the outside space; and an HVAC controller that is programmed to determine whether modification of the air temperature of the inside space is desired by comparing the air temperature of the inside space with the set-point, wherein if modification of the air temperature is desired, the HVAC controller commands the HVAC unit to start the heating mode or cooling mode.

Description

[0001]The present invention claims priority to U.S. Provisional Application No. 62 / 381,562, filed on Aug. 30, 2016, which is incorporated by reference for all purposes as if fully set forth herein.FIELD OF THE INVENTION[0002]The present invention relates to an automatic HVAC control system.BACKGROUND OF THE INVENTION[0003]HVAC (Heating, Ventilation and Air Conditioning) is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC design is a sub-discipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer.[0004]HVAC equipment needs a control system to regulate the operation of a heating and / or air conditioning system. Usually a sensing device is used to compare the actual state (e.g. temperature) with a target state. Then the control system draws a conclusion as to which action shall be taken (e.g. starting or stopping the blower).[0005]The contro...

AI Technical Summary

Benefits of technology

The present invention is an automatic HVAC control system that includes a first temperature sensor to measure the air temperature of the outside space, a second temperature sensor to measure the air temperature of the inside space, a memory to store a set-point for the HVAC unit, a set-point controller to adjust the set-point based on the air temperature of the outside space, and an HVAC controller to determine whether modification of the air temperature of the inside space is desired by comparing the air temperature of the inside space with the set-point and command the HVAC unit accordingly. The set-point can be adjusted based on the air temperature of the outside space and the humidity of the outside space. The automatic HVAC control system allows for automatic adjustment of the HVAC unit based on the air temperature and humidity of the outside and inside spaces, providing efficient and effective control of the air temperature.

Problems solved by technology

Therefore, the control system cannot efficiently and economically to control HVAC equipment to provide comfort and save energy at the same time.
