Description

DISTRIBUTED HEATING and COOLING SYSTEM

FIELD of TECHNOLOGIES

The present disclosure relates to space heating and cooling (air conditioning) system, for building and transport instrument. The disclosure especially relates to a distributed positional/locational heating and cooling device and system for a residential building space and a space of electric and hybrid transport instrument. The cooling device of the system may employ air pressure caused by the moving transport instrument.

BACKGROUND

This application claims the priority of Canadian patent application No. CA2,974,909, titled Heating and Cooling System for Transportation Instruments.

Heating and cooling device and system are required by most of all spaces of buildings and transport instruments. The building can be any building of residential, commercial and industrial buildings. The transport instrument can be any one of road transport, air transport instrument, maritime transport and rail transport. To save the heating and cooling energy of the buildings and the transport instruments is to reduce the greenhouse gas emission, especially when the transport instruments are starting to turn to electric or hybrid transport instruments and the building starts using solar electricity for heating and cooling. Following we uses an electric vehicle and a space of residential building as examples for all buildings and transport instruments. The ideas devices and systems disclosed in this application can be used for all buildings nd transport instruments.

The energy consumption of air conditioning for an electric vehicle is about 5%-15% of the total energy consumption of the vehicle, depending on the design, local weather and how a driver to use the air conditioning system. To save energy from air conditioning of an electric transportation instrument is not only to save the energy, but also to reduce the battery weigh and cost, to extend the cruise millage of the vehicle. There are some ways to save energy for air conditioning such as to increase energy efficiency and to improve the insulation of the air conditioning system of the vehicle.

The traditional and present space heating and cooling systems for a building waste a lot of energy. For example, especially for the residential building, at day time, all bed rooms may not need heating and cooling. At night time, there is no heating and cooling required in the spaces of dining room, sitting room, kitchen room and library, except the space of bed room. Even in the bed room, at most of the night time, may only the sub-space of the location of the beds requires heating and cooling. Therefore to develop a distributed heating and cooling system for the subspace where residents are located can save huge energy of heating and cooling. Furthermore the sub-space air conditioning will help reduce the temperature differences between the walls and outer environment to reduce energy loss through walls and windows.

This disclosure introduces a new concept, device and system of space air conditioning (heating and/or cooling) for spaces of transport instruments and buildings, especially for full electric and hybrid transport instrument and for residential buildings. The main idea is to create a dynamic air conditioned micro environment surrounding occupants in the space instead to provide air conditioning for full space. The first step is to provide a set of distributed heating and/or cooling devices distributary arranged in the space. The devices are able to locational and directionally heat or cool the sub-spaces where occupants may be located or closed. Then to heat or cool all space of building or full cabin space of the transport instrument is not required. Here the heating and/or cooling devices include distributed and directional air outlets of a center air conditioning system. They may or may not with a rotatable air outlet. The second step is to build a dynastic monitoring and detecting sub-system in the heating and cooling system for locating and indicating the sub-space (location) of the occupants. The monitoring and detecting system may comprise sensors, devices and softwares for signal collecting, analysis and calculation. The system makes the distributed heating and cooling system to be a locational and positional heating and cooling system. The system only supplies heating or cooling for the occupant and his/her surrounding place.To allow the electric heater and/or cooler close to the occupants, they need to operate under low voltage, low operation temperature. They may also need fast temperature rising and may be a soft device. Several new components mentioned in claims and descriptions are introduced in this disclosure. The third step is to control the air conditioning working temperature, starting and operating times of heating and cooling supply etc. The control system comprises mechanical and/or electrical switchers, thermometer and computer control hardware and software etc. In this disclosure we set at least two working temperatures for the space: a base temperature is for the full space continuously and a confortable temperature for sub-space where occupants are located. To make the system works at a high efficiency, an Al (artificial intelligence) sub-system also invited to allow the system learn from the operation of the system and improve the operation processing.

This disclosure also introduced following devices for the heating and cooling system of transportation instruments. 1. An air cooling device that transfers the air pressure of a moving vehicle to a power source for generating cooled air. An air channel having a solid and/or soft wall is employed which has a larger size of air inlet and a smaller size of air outlet. 2.To heat and cool the space of transport instrument and building by solar energy through a shade cloth and a controllable slide sunroof. To preheat the transport instrument by external electric power which is for charging the battery.

Fig. 2 is schematic top view illustrating a sub-control panel for a passenger's heating and cooling Fig. 3 is schematic top and side view illustrating a heating and cooling system for a space in building. In the figures which illustrate exemplary embodiments of this invention: DETAILE DESCRIPTION

Refer to Fig. 1, a heating and cooling system of an electric vehicle 10 is illustrated in side view. This is a right side driver vehicle. The vehicle 10 comprises an occupant (driver and passenger) 11, here is a driver. 121, 122, 123 are the distributed batteries to provide power for vehicle operation. The battery is charged by external power through changing cable 161. The vehicle 10 further comprises weal 13, backup air conditioner 14 and electric motor 15. The vehicle 10 also comprises front seat 171 and rear seat 172. A main electric controller 18 (also called computer controller) control the operation of all elements of the vehicle. A main control panel 181 arranged at the front of the driver 11. Fig. 1 also shows the window 19, shad cloth 28, temperature sensor 29 and the climate sensor or meter 27. The electric power cable and signal cable 16 connect all electric devices and the devices of control systems to battery to provide operation power and transfer signals. In Fig. 1, there is only one sample 16 is shown and marketed, other did not show or market in Fig. 1. They may comprise the sensors, heaters, detectors, controller and control panel.

When the driver 11 gets into his/her seat 171, a condition detector detects the person. The seat condition detector can be any detector to identify whether or not an occupant is on seat. For example, the detector may be a weight sensor under seat or a light sensor 25. Here it is a video camera 26. The video camera takes an image of cabin. The computer 18 of the control system identifies the seat condition. The condition detector (here is computer) then sends a signor to a switcher to turn on the power directly from buttery 122 for the build in first heater 21 which is arranged in the seat 171 under the seat cover and over the seat insulation. When the area temperature surrounded the driver reaches to the setting temperature, the temperature sensor 29 send a signal to the control system. The control system turns off the power. In the backrest of seat 171, a second heater 22 is built in and under the rear cover of the backrest. The second distributed heater 22 is a far infrared heater mainly for the passenger on the rear seat 172. It also helps to warm the driver 11.

Here the heater (21 or 22) is distributed heater for each occupant. The heater is a locational/positional heater that arranged near to each occupant and heats a designed passenger. Therefore, the distributed heater (21 or 22) needs to be operated at a low and safe voltage for safety reason. For example the voltage may be 12V, 24V of battery voltage or lower). Its operation temperature needs to be low and safe temperature too (e.g. 60 degree C and under). It may be soft (e.g. a film) for safety reason. The heating material may be an electric heating coat coated on a surface of a soft insulation material. The heating material may also be a striped film. It may connect to the buttery directly and supply power by the buttery directly. The heater can be a directional far infrared heater. The heater can heat the driver/passenger directly instead to heat the surrounding environment. It may be build-in heater. It can be arranged at the front of the occupant, under the cover of a seat, in the backrest of the front seat or at the top of the occupant.

The heating controller of the heater 21 is at the main controller 18. The main controller has a control panel 181. The heater 22 has a sub-control panel 20 arranged at armrest of the rear door of the vehicle for the convenient of the passenger. The buttery supplies the electric power to the main controller 18 and sub-controller 181 including the distributed heater 21. The condition detector 26 is on. The heater 21 starts to provide heat to the driver through default setting or last setting. The identification of the passenger is completed by the control panel through personal biological information detected. When the driver leaves the seat, the detector sends the information to the controller to turn off the power automatically. When the heater 21 heats the driver, the heater may also provide heat according to the passenger's desired setting. This will discuss in Fig.2.

The distributed heating system may comprise a power adaptor (did not show in Fig. 1) for AC to DC. It provides DC electric power to the heater by external AC power supply. The power adaptor can be connected to a branch of the changing cable 161. The control system controls the switching between buttery DC power supply and the external AC power supply.

Here the control system comprises a main control system 18 for control all elements of the transport instrument including the heating and cooling system. The main control system is controlled automatically or by the driver 11 of the transport instrument. The main control system may comprise a computer 18 and relevant programs. The control system also comprises a heating and cooling sub- control panel 20. The sub-control panel is for control a distributed heater 22 and cooler 35 and the special location of an occupant sited on seat 172. The sub-control panel is mainly controlled by the passenger. Some or all features of the sub-control panel may also be controlled by the driver through main control panel 181. The heating and cooling sub-control panel can be arranged at a backrest (e.g. 171 or 172), an armrest of a door armrest (e.g. 20) of rear seat and dashboard etc. The heating and cooling sub-control panel may comprise an electric power indicating light 206, heating and cooling power switches (201, 202), desired temperature settings temperature increasing or decreasing buttons (203, 204), and current temperature indicators (205). The sub-control panel can be in one panel or separated in several panels. One sample panel surface is shown in Fig.2.

The heating and cooling system of the transport instrument comprises a sun roof 37. The sunroof comprising a sliding window 38 and a sun visor 39. 38 and 39 may be a solar electric generation panel and a transparent plate. They may also a translucent plate and a opaque plate. The sun roof 37 comprises a built in main climate controller (did not shown). The climate controller controls the opening and closing of the sun roof and adjusts the size of air gap of the sunroof automatically and manually. The sunroof climate controller also comprises climate sensor(s) or measuring device for temperature, sunlight, air pressure and humidity. Thereis. a photometer 27 to measure Luminosity of sunlight. The sun roof weather controller also comprises thermometers to measure the temperature inside and outside of the cabin. When the vehicle in operation and the temperature in the cabin is higher than the desired temperature, the sunroof may open for cooler air come into the cabin. When the vehicle is packed, the photometer indicates a luminosity of sunlight and the thermometer indicates a temperature in cabin higher than the environment temperature, the sun roof opens an air flow gap for the cabin to release the hot air in cabin and get cooler air from lower place of the cabin to cool the cabin. When the temperature in the cabin is low and the sunlight is available, a transparent sun visor receives extra sunlight into cabin and heat the cabin. When luminosity is low to a level of raining situation, the sunroof is closed by the sun roof weather controller automatically. When the sunroof is closed, the solar electric generating plate generates electricity. The heating and cooling system further comprises a cooling device 30. The cooling device transfers the air pressure of the moving car 10 to cooling air in the channel 31. The air channel 31 has a larger air inlet port 34 facing toward to the moving direction of the vehicle 10 and a smaller outlet 34 connected to air vent 34 for proving cool air under the controlling of occupant. The channel 31 has another air vent 35. Either hard material or soft material, including their combination, can be used to make the channel wall. The channel may be made of hard material, e.g. plastic, metal, wood, and other hard materials. The channel also may be made of soft material, e.g. a dense cloth, a metal foil, a plastic film and other soft materials. The channel may also be a continued and curved channel. It also can be a group of channels to provide cool air for each occupant. An air direction guider directs the air flow for different occupants, (not show in Fig. 1). A structure 32 is for opening and closing the air channel. A grille/net 34 and an air filter 33 are arranged at the inlet of the channel to ensure the quality of the cooling air. The outlet 35 of the channel 31 may also be a group of uniformly distributed small gaps, e.g. a grid-like cloth. Of cause the inlet 32 of the channel 31 is much larger than the outlet 34 and 35 of the channel 31. When the vehicle 10 is moving, the external air gets into the channel 31 from a larger inlet 32 and through a smaller outlet 34 to go in a large cabin space. Because the inlet air is forced by the air pressure of the moving vehicle, so the outlet air is cooler than the inlet air. This is how the cooling device 31 works. As faster the vehicle move, as cooler the outlet air. A back up air conditioning device 14 is required, in case the vehicle is forced to drive slowly at a heavy traffic period of time. The heating and cooling system of the transport instrument further comprises a fan to circulate the air or pump the air into or out to the cabin.

The heating and cooling system further comprises a heat low-emission (Low-E) material at the window 19. The Low-E material is arranged at outdoor side of a window at a hot area. The Low-E material is arranged at indoor side of a vehicle window at a cool area. The Low-E material also can be arranged in between of two glasses that are laminated.

The heating and cooling system further comprises a shade cloth 28. The first side of the shade cloth has sunlight reflect material to reflect the sunlight and cool the cabin at hot weather. The second side of the shade cloth has a heat absorb material for absorb solar heat at cool weather. The heat absorb material may be transparent or translucent. The heat reflecting material may be translucent. The shade cloth also protects the heat loss through window by heat emission. The shade cloth can be fixed to the window or removably attached to the window. In comparing with the low-E glass, the shade cloth can absorb more solar heat and provide much more flexibilities.

Refer to Fig. 2, a sub- control panel 20 of heater 22 is illustrated on top view. The heating and cooling sub-control panel comprise an electric power indicating light 206, heating and cooling power switches (201, 202), desired temperature settings buttons (203, 204), which increasing or decreasing the setting temperature and current temperature indicators (205). In Fig. 2, H and C means heating and cooling presented the right side buttons are for the heater 22 and cooler 35. 201 and 202 "On/off buttons mean the buttons are for turning on and off the setting of the heater and cooler. The buttons 203 and 204 with arrow "up" and "down" have following meaning: when puss the upper side of the button is to increase the temperature surround the passenger. When to puss the down side of the button that is to decrease the temperature surround the passenger. The red star 205 is a light signal of the panel power. The last one 206 is a temperature indicator indicating the present temperature setting. When the passenger sit down at seat 172, the detector 25 (or 26, if 25 is not exists) send a signal to control system. The red light turns on. The heater 22 and cooler 35 start work based on the last temperature setting. The temperature indicator 206 shows the current temperature setting. If the passenger is comfortable with the temperature setting, nothing needs to do. If the passenger is not comfortable with the temperature setting, the passenger can push the button and set a desired temperature. The control system will guide the heater or cooler get the proper temperature. When the passenger leaves the seat, the detector sends the information to the controller to turn off the power of the heater 22 and cooler 35. The control panel 20 automatically turn off to save electricity.

Refer to Fig. 3, a distributed heating and cooling system 30 for a room space 30 1 in a residential building is illustrated by side view.

Space 31 of a residential building is a room and separated by top wall 311, side walls 312, 313 and floor 314. Other two side walls are removed in the figure for clear watching. The top wall 310 is transparent. In the room, a long strip shaped carpet 317 is arranged on the floor. A table 315 with a chair (not show in Fig.3/3) for working and close to side wall 313. A bed 316 arranged in the room and close to side wall 312 for sleeping. In the heating and cooling point of view, the room can be divided into three sub-spaces The walk sub-space is on the carpet. Working sub-space is the area of table 315 and chair. Sleeping sub- space is on the bed. Following heaters and or coolers are arranged in the room. The carpet 317 has a soft and film shaped electric heater 321 combined in the carpet or under the carpet. The table 315 (and chair) has a heating firm 324 under the surface of the table. The bed 316 has a firm heater 322 and a panting heater 323 arranged on side wall 312. A far infrared light heating device 325 is arranged under the top wall 311 to provide heat for the space. 325 may be rotatable or movable around a track. So it can supply heat to any sub-space in the space and follow the moving path of the occupant. Except 325, all other heaters 321, 322 and 323 are work under low voltage through an adapter or voltage transformer. The temperature can be controlled locally by use and by control system 35. There are three grids 326, 327 and 328 as distributed heaters and/or coolers arranged in three sub-spaces. They are connected to an air channel 329 from a center air conditioning device. They are controlled by control system 35 to open and close. They may also have rotatable blades to directionally supply the heated or cool air.

Following temperature sensors are arranged to measure and monitor the temperatures of the heaters and coolers. Sensor 331 is under the carpet. Sensor 332 is on the side wall of 312. Sensor 333 is on the sidewall 313.

A light detector 341 arranged toward the carpet and has a light pass through all carpet for detect the occupant on the walk sub-space. A pressure sensor 342 is arranged at the corner of the table and is connected to control system 35. Another pressure sensor 343 is arranged at the bed to detect the occupant on bed and is connected to control system 35 too.

A control system 35 connects to all components of the system, e.g. heaters, coolers, sensors and doctors to collect the data for calculating and analysis, then the system to control the working of the heating and/or cooling system. The control system 35 has interface like button 351 and screen 352 to check the data and setting the data and working processing of system.

Please note that in both spaces 10 and 31, two temperature settings are arranged in the control system: a base temperature and a working temperature. The base temperature is set for full space continuously. For example, at winter in building space 30, the base temperature setting may be 5 degree Celsius to protect the water from freezing. At summer in the space of transportation instruments 10, the base temperature may be 40 - 45 degree Celsius to provide a basic working environment for the electronic devises. The base temperature also avoids the person to accept an unacceptable temperature at the beginning when he/she come into the space. The working (confortable) temperature is set for the sub- space when an occupant entered.

Power supply 36 provides the electric power fot all the components of the system 30. All the cables and accessories of the power supply are hided.

When the space 31 is empty, the control system 35 controls the heaters and/or coolers to work at the base temperature. For example only heater 321 works to keep carpet warm and the room under a low temperature. Or only cooler 326 works to provide cool air and the cooler 327 and 328 are closed. When an occupant enters to the room, the light detector 341 sends a signal to controller. The controller controls the heater 321 to work and provides a warm temperature in the walking sub-space. When the occupant starts work, the sensor at chair and table will detect and the heater 324 starts to heat the working sub-space. The heater 321 is turned off. When the occupant goes to bed, the control system gets information from sensor 343, then the heater 322 and 323 work. The heater 321 and 324 are turned off. At the beginning of each heater start work, the temperature of the sub-space may low and the occupant feels not confortable. The control system 35 will turn on the rotatable or movable heater 325 to provide a small warm environment surround the occupant.

If the space 30 is a baby room, a camera image monitor 345 may be installed to detect the occupation position of the space. The images received by the monitor 345 can be sent to the controller 35. After comparing and analysing the data, the controller will detect and locate the occupant in the space to turn on or off the proper heater and or cooler. The processing is similar or the same as the processing mentioned above. In this case, the detect devices 341, and the sensors 342 and 343 are not necessary.

Other modifications will be apparent to those skilled in the art and, therefore, the invention is defined in the claims.
