Description

Technical Field

[0001] This invention relates to the field of building thermal management system technology, and more particularly to a building thermal management system and control method, and intelligent building. Background Technology

[0002] Current indoor underfloor heating systems typically use copper or PVC pipes filled with hot water, buried beneath the floor or tiles for heating. Cooling is similarly limited, often relying on air conditioning for overall indoor cooling, with manual temperature adjustments. Nearly half the rooms are set to temperatures outside the comfortable range – either too cold or too hot – resulting in both discomfort and significant energy waste. This also leads to energy waste when no one is in the room. Therefore, in the context of promoting green and low-carbon practices, a smart thermal management system is needed that can automatically adjust the temperature based on the needs of occupants, achieving rational and maximized resource utilization. Summary of the Invention

[0003] This invention provides a building thermal management system and control method, as well as an intelligent building, to solve one or more technical problems encountered in the prior art.

[0004] In a first aspect, embodiments of the present invention provide a building thermal management system, comprising:

[0005] Building envelope, wherein at least one temperature-controlled space is defined within the building envelope;

[0006] A distributed temperature detection unit is installed in the space requiring temperature control and / or on the surface of the building envelope, for collecting the real-time temperature of the space requiring temperature control and / or the surface temperature of the building envelope;

[0007] An active heating device and an active cooling device are thermally coupled to the space requiring temperature control, and are used to heat or cool the space.

[0008] Building energy interface, which is electrically connected to the municipal power grid, distributed energy system and / or energy storage device, for supplying power to the system and / or receiving reverse power;

[0009] A central control system, which is electrically and communicatively connected to the distributed temperature detection unit, is used to receive and process temperature data.

[0010] An energy distribution and equipment control switch array is electrically and communicatively connected to a central control system, and is also electrically connected to a building energy interface, a heating device, a cooling device, and an energy storage device, respectively.

[0011] The central control system is configured to compare the received real-time temperature with a preset comfort temperature range; wherein the comfort temperature range includes a lower limit first temperature threshold and an upper limit second temperature threshold.

[0012] When the real-time temperature is lower than the first temperature threshold, the central control system sends a first control signal to the energy distribution and equipment control switch array, and the energy distribution and equipment control switch array controls the heating device to start operation and heat the space that needs temperature control.

[0013] When the real-time temperature is higher than the second temperature threshold, the central control system sends a second control signal to the energy distribution and equipment control switch array, and the energy distribution and equipment control switch array controls the refrigeration device to start operation and cool the space that needs temperature control.

[0014] When the real-time temperature is between the first temperature threshold and the second temperature threshold, the central control system sends a third control signal to the energy distribution and equipment control switch array, which controls the heating device and the cooling device to enter a low-power standby or off state.

[0015] In a preferred embodiment, the active heating device includes one or more of the following: a radiant heating layer integrated into the floor, wall, or ceiling; a heat pump system; a variable frequency air conditioning heating unit; or a solar-assisted heater.

[0016] The active cooling device includes one or more of the following: a variable frequency air conditioning unit, a radiant cooling layer, a phase change cold storage ceiling, or a natural cooling system based on underground wind.

[0017] The heating and cooling devices are independently controlled and adjusted according to the building's zoning.

[0018] In a preferred embodiment, it also includes an outdoor meteorological monitoring unit, which is communicatively connected to the central control system, for collecting outdoor temperature, humidity, solar radiation intensity and wind speed data.

[0019] The central control system is also used to predict the heat load for future periods based on outdoor meteorological data, historical energy consumption data and building thermal inertia models, and to adjust heating or cooling strategies in advance.

[0020] In a preferred embodiment, the building energy interface is also connected to a building-integrated photovoltaic system, a wind power generation device, or an energy storage battery.

[0021] The central control system is also used to optimize energy allocation strategies based on time-of-use electricity price signals, the building's own power generation capacity, and space temperature requirements, prioritizing the use of distributed energy to power heating or cooling devices, and charging energy storage devices during off-peak electricity prices or when there is a surplus of power generation.

[0022] In a preferred embodiment, the system further includes a personnel sensing unit, which includes an infrared sensor, a CO2 concentration sensor, or a smart meter data interface, for detecting the presence and activity intensity of personnel in the temperature-controlled space.

[0023] The central control system is also used to dynamically adjust the comfort temperature range and equipment operating power of different zones by combining personnel perception information.

[0024] In a preferred embodiment, the distributed temperature detection unit includes a wireless temperature sensor network arranged on different floors, facing different directions, and in different functional areas.

[0025] The central control system identifies thermal non-uniformity within the building based on data from various sensors and independently controls the heating or cooling devices in the corresponding zones to achieve precise local temperature control and eliminate overly cold or overheated areas.

[0026] In a preferred embodiment, the system further includes a humidity detection and adjustment unit connected to the central control system;

[0027] The central control system is further configured to: while controlling the temperature, control the dehumidifier, humidifier or fresh air system in conjunction with the collected humidity data and the preset comfortable humidity range to maintain the overall comfort of the indoor thermal and humid environment.

[0028] In a preferred embodiment, the central control system is integrated into the building energy management platform and has an interface for communication with the grid demand-side response system.

[0029] When the central control system receives a peak-shaving or load-reduction command from the power grid, it temporarily adjusts the operating power or starts / stops the heating or cooling devices within a buffer zone where the indoor temperature is acceptable, thus participating in power grid ancillary services.

[0030] Secondly, embodiments of the present invention provide a control method for a building thermal management system, comprising the following steps:

[0031] S10: Continuously monitors the real-time temperature of each temperature-controlled space in the building through distributed temperature detection units;

[0032] S20: The central control system compares the real-time temperature of each zone with the comfortable temperature range set for that zone;

[0033] S30: If the real-time temperature of a certain area is lower than its first temperature threshold, a heating program for that area will be initiated, and the energy allocation strategy will prioritize the use of distributed energy or energy storage power.

[0034] S40: If the real-time temperature of a certain area is higher than its second temperature threshold, then start the cooling program for that area.

[0035] S50: During the heating or cooling process, it monitors temperature changes, energy consumption and personnel status in real time, and dynamically adjusts the equipment output power until the temperature returns to the comfortable range.

[0036] S60: When the temperature in all areas is within the comfort range, the system enters energy-saving cruise mode, maintaining only the minimum necessary ventilation and monitoring.

[0037] Thirdly, embodiments of the present invention provide an intelligent building, including a building thermal management system, which serves as part of the neural network of the intelligent building to enable the building to have adaptive, efficient, and intelligent management of the thermal environment.
