Abstract
Described herein is a free cooling and heating system for a multi-storey building. The system includes a plurality of temperature sensors configured to measure temperatures on different floors, an air handling unit (AHU) integrated with an HVAC unit, including at least one blower unit configured to transfer air between the different floors. The system further includes at least one motorized damper positioned within a Wye branch, with the Wye branch configured to connect the HVAC unit with the AHU to transfer conditioned air to the required floor, and a computing device operatively connected to the plurality of temperature sensors, the air handling unit, and the at least one motorized damper of the Wye branch.

A free cooling and heating system for a multi-storey building, the system comprising:
- a plurality of temperature sensors configured to measure temperatures on different floors;
- an air handling unit (AHU) integrated with a HVAC unit, and including at least one blower unit, the at least one blower unit configured to transfer air between the different floors;
- at least one motorized damper positioned within a Wye branch and configured to connect the HVAC unit with the AHU to transfer conditioned air to the required floor;
- an air duct system connecting the AHU, the Wye branch, the HVAC unit and the floor air distributing fittings;
- a controller;
- and
- a computing device operatively connected to the plurality of temperature sensors, the air handling unit, the HVAC unit and the at least one motorized damper, the computing device configured to:
- receive temperature data from the plurality of temperature sensors;
- determine when a predefined differential threshold is exceeded;
- activate the air handling unit to transfer air between different floors;
- regulate conditioned airflow through the at least one motorized damper;
- operate the HVAC unit;
- and
- dynamically adjust a speed of the at least one blower unit and a position of the at least one motorized damper based on at least one of real-time temperature data and user input.
A method for balancing temperature differentials between different floors in a multi-storey building, the method comprising:
- detecting, by a plurality of temperature sensors, temperature variations between floors;
- determining, by a computing device, whether a predefined temperature differential threshold is exceeded;
- activating, by the computing device, an air handling unit (AHU) to initiate airflow redistribution when the predefined temperature differential threshold is exceeded;
- operating, by the computing device, at least one motorized damper to regulate airflow from the HVAC unit;
- and
- monitoring, by the computing device, temperature variations and deactivating the system components when temperature equilibrium is achieved.
