Abstract

Heat activated panel is comprised of a basic panel to which two countercurrent ventilated openings are added on the outside. Through the inner opening waste air from a building exits, and through the outer opening fresh air enters the building. Due to heat activation the temperature difference between inner and outer surface of the panel is much smaller as temperature difference between inner surface of the panel and the environment. As a result of smaller temperature difference one encounters lower transmission heat losses in winter time and lower heat gains during summer time. Along the current of waste air in the inner opening the heat transfer between waste air and fresh air is taking place, said fresh air flowing in outer opening from the environment into the building. The outer surface of heat activated panel is absorbing solar energy whereby in the outer opening the fresh air is additionally heated.

Description

HEAT ACTIVATED PANEL
DESCRIPTION OF THE INVENTION
Field of the technology
Heat recuperation, heating, cooling, energy saving, heat insulation, heat transfer
Description of the problem
To provide-appropriate living conditions one needs to account for sufficient quantity of fresh air (oxygen) within rooms of the building. If the temperature of the surrounding significantly differs from the desired temperature inside the room one needs to ensure appropriate conditions by heating (or cooling), or in order to save energy one needs to provide costly heat exchangers - heat recuperators and heat receivers - e.g. solar collectors. Due to increasing demands for energy saving one attaches heat insulation onto the buildings, in case of larger buildings in form of panels which represent element of the building covering. The solution at hand will have to functionally connect the operation of the basic panel with solar energy receiver and heat recuperator while providing ventilation of the building whereas the invention at hand is technically easily implemented and reasonably priced.
State of the art
To provide for appropriate living conditions inside of rooms one needs to provide for heat balance with the environment whereas the appropriate amount of the fresh air must be provided for.
The problem with providing of sufficient amount of fresh air is apparent in particular in the buildings where several people are present within relatively small room (e.g. manufacturing buildings, classrooms in schools and kindergartens, cinema halls ...). The problem of using of heat of waste air is successfully solved by using heat recuperators, however, they are costly. Investment in recuperators can be justified economically by return in ten, twenty or more years assuming no large maintenance costs occur for recuperator maintenance.
The literature survey and patent application survey shows wide use of systems for air exchange within the buildings and use of energy from waste air or use of heat from the environment.
In addition the solar collectors are well known from the literature, said collectors acting as receivers of solar energy transferring energy converted into heat by using medium into the heat accumulators (for example into reservoir for warm sanitary water). The problem with collectors is that they are least efficient during cold days when the need for energy is the largest, and further, that they are often covered with snow as they are usually positioned horizontally or under relatively small angle relative to the horizon.
Also, the ventilation using openings (slits) on the outside wall of the building or on the outside side of the basic panel which serves as heating insulation of the building is known.
None of reasonably priced solutions currently combines operation of the basic insulation panel with receiver of solar energy and heat recuperator.
Description of new invention
Heat activated panel is subject of this invention and shows the panel which functionally combines operation of three different elements or devices: basic panel which presents building covering,
- receiver of solar energy, and
- heat recuperator for ventilation of the building (or other object in need of ventilation)
Heat activated panel is comprised of a basic panel to which two countercurrent ventilated openings are added on the outside. The inner opening which provides for activation of said panel the waste air from the building enters, e.g. on the top side. Due to heat activation the temperature difference between inner and outer surface of the panel is much smaller as temperature difference between inner surface of the panel and the environment. As a result of smaller temperature difference one encounters lower transmission heat losses in winter time and lower heat gains during summer time. Along the current of waste air in the inner opening the heat transfer between waste air and fresh air is taking place, said fresh air flowing in outer opening from the environment into the building. The outer surface of heat activated panel is absorbing energy of solar heating whereby in the outer opening the fresh air is additionally heated whereas the use of energy for heating of fresh air is further decreased.
The essence of the invention is described in greater detail below by description of the preferred embodiment and by description of the figure, said figure forming integral part of this patent application, and showing:
Figure 1 shows basic panel 1 , inner covering (envelope) of the panel 2, outer covering (envelope) of the panel 3.
Figure 1 shows preferred embodiment where inner covering of the panel 2 and outer covering of the panel 3 are added to the basic panel 1. The basic panel 1 and inner covering of the panel 2 form inner opening through which the waste air is exiting the building. The inner covering of the panel 2 and outer covering of the panel 3 form outer opening through which the fresh air from the environment is entering. Between both openings (slits) there is inner covering of the panel 2 which is made of sheet metal or any other heat transferring material. Through inner covering of the panel the heat is transferred between waste and fresh air. The system of ventilation openings is implemented as countercurrent heat exchanger or cross flow heat exchanger.
The heat is transferred between waste air and fresh air, while at the same time the basic panel is heat activated meaning that the temperature difference between inner and outer surface of the panel is significantly lower as temperature difference between inner surface of the panel and the environment. Due to this, the heat losses through the covering (envelope) of the building are significantly lower as the temperature difference is driving force for heat transfer and resulting heat losses.
During period when the desired temperature for inside of the building is higher than temperature of the environment the warm waste air exits through the inner opening, whereby:
- said warm air on the outer side of the basic panel provides for higher temperature as temperature of the environment therefore decreasing heat losses through the panel, and through the inner covering of the panel the heat is transferred onto the inlet fresh air entering from the environment therefore decreasing need for additional heating.
The outer covering of the panel is receiving energy of the solar radiation. With influx of fresh air between both coverings the fresh air is also receiving heat from the outer covering of the panel. Using additional coatings on the outer side of the outer covering of the panel the share of the energy obtained from solar radiation is further increased.
During period when the desired temperature for inside of the building is lower than temperature of the environment the cold waste air exits through the inner opening, whereby:
- said cold air on the outer side of the basic panel provides for lower temperature as temperature of the environment therefore decreasing heat gain through the panel, and
- through the inner covering of the panel the heat is transferred from the inlet fresh air entering from the environment therefore decreasing inlet temperature of said fresh air.
For regulation, control, and optimization of the process the computer program can be used, said program comprising programming means for regulation of air flows, said computer program running on general purpose computer. It is self evident that this solution can also be performed in different embodiment which does not alter the essence of the invention.
