Abstract:
1. An integrated heating and cooling system for a living space of a building that can achieve and/or maintain a desired temperature in the living space, comprising; (a) a solar-based heating and cooling system that includes a roof assembly that includes a roof, a roof space in heat exchange relationship with at least a section of the roof, the roof space being isolated from a living space, and a chamber that includes (i) one or more than one inlet for airflow from the roof space into the chamber, (ii) one or more than one first opening having a flow control apparatus for airflow from the roof space via the chamber to outside the building altogether, the flow control apparatus allowing air to flow from the chamber to outside the building to cool the building when an outside temperature outside the building is higher than a desired temperature in the living space, and (iii) one or more than one second opening for airflow having a second flow control apparatus for airflow from the roof space via the chamber to a living space of the building, the second flow control apparatus allowing air to flow from the chamber to a living space to heat the living space when the outside temperature is lower than the desired temperature in the living space, and to cool the living space when the outside temperature and/or a roof space temperature is lower than an inside temperature in the living space, and the inside temperature is higher than the desired temperature, (b) a fossil fuel-based heating and cooling system that relies directly or indirectly on fossil fuels, and (c) a controller that monitors temperatures and, subject to monitored temperatures, firstly operates the solar-based heating and cooling system to heat and/or cool the living space and, when heating and cooling requirement cannot be fully met by the solar based heating and cooling system, thereafter operates the fossil fuel-based heating and cooling system to heat and/or cool the living space, to achieve and/or to maintain the temperature in the living space at the desired temperature, and (d) a plurality of temperature sensors that monitor temperatures in the living space, externally of the building, and in the solar-based heating and cooling system, wherein the sensors input data into a program of the controller on a continuous or periodic basis and the program processes the data and operates the solar-based heating and cooling system and, when heating and cooling requirement cannot be fully met by the solar based heating and cooling system, the fossil fuel-based heating and cooling system to achieve and/or to maintain the desired temperature in the living space.
