Abstract
A heating and cooling system for controlling and regulating the temperature within a building envelope (10) having roof and wall cavities (14) adapted to receive replaceable foam liquid. The interior of the building envelope (10) is maintained at any specific controlled temperature by controlling the temperature of the liquid foam. The temperature of the liquid foam within the roof and wall cavities (14) is sensed and when a change in temperature is detected, a dynamic liquid foam regeneration unit is triggered so as to supply new liquid foam at an appropriate temperature so as to maintain the overall temperature of the liquid foam in the roof and wall cavities (14) substantially constant.
Claims13
A method of controlling the temperature within a building envelope having roof and wall cavities adapted to receive liquid foam, the method comprising the steps of:
- a) providing liquid foam at a selected controlled supply temperature within said roof and wall cavities, and b) controlling the temperature of said liquid foam while in use in the roof and wall cavities so as to maintain said temperature within a range of temperature determined as a function of a desired control environment temperature within the building envelope.
A heating and cooling system for controlling the temperature within a building envelope having roof and wall cavities adapted to receive replaceable liquid foam insulator, comprising a liquid foam generating unit for providing liquid foam at a preselected temperature within said roof and wall cavities, a sensor for sensing the temperature of the liquid foam in the roof and wall cavities, and a control unit for actuating said liquid foam generating unit when the sensed temperature starts to fall outside of a predetermined range of temperature so that new liquid foam be generated within said roof and wall cavities at said preselected temperature in order to maintain the temperature of said liquid foam in said roof and wall cavities within said predetermined range.
