disposed within the hollow interior of the sealed enclosure. The thermally conductive liquid is capable of being transported through the wick portions, with the liquid being evaporated by the transfer of heat from the item to be cooled into the first wick portion. The vapor is then condensed on various surfaces such as those defined by internal components, as well as the surface of the thermally conductive liquid.
There is disclosed a combined heat and power system for a building having a heat demand comprising a primer mover an electricalgenerator, adapted to provide building power, the said prime mover being drivinglyconnected thereto a heat recovery arrangement said heat recovery arrangement being connected to the prime mover and recovering heat therefrom, and adapted to provide building heating, and a control arrangement adapted automatically to control the prime mover in response to said heating demand.
4880054 HEAT EXCHANGER TUBE FOR EVAPORATION OR CONDENSATION Takayuki Yoshida, Masao Fujii, Kiyoshi Sakuma, Shizuoka, Japan assigned to Mitsubishi Denki Kabushiki Kaisha A heat exchanger tube for evaporation or condensation, comprising: proje~ed parts having cavities and provided on at least one of the inner wall surface and the outer wall surface of a tubular body, and plain parts formed on the same surface as the projected parts so that the projected parts and the plain parts mingle together.
4880157 CAPACITY CONTROL FOR INTEGRATED FURNACE Jay L Boot, Chester D Ripka, Ian Shapiro assigned to Carrier Corporation A method and control system are disclosed for operating an integrated heating system for space heating and tankless domestic hot water heating utilizing an infrared burner module and heat exchanger coil. When the system is below 100% capacity, the burner is pulsed using a constant pulse period and varying the on-pulse width to vary capacity, or where a minimum on-pulse width is maintained the off-pulse width is varied to vary capacity.

An adsorption refrigeration system comprising adsorption columns housing a solid adsorbent and heat transfer tubes and sealed with a refrigerant, an evaporator, a condenser, and pipe lines connecting them together so that the refrigerant may be circulated, the pipe lines being equipped with valves, preferably, butterfly valves, capable of opening or closing by means of internal pressure difference between the evaporator side and condenser side and driving force of eccentric valve shafts. The system is operated by alternatively changing over adsorption and resorption stages between the one adsorption column(s) and the other column(s) so that both columns may be at mutually reverse stages; shortly before change-over, tranfferring whole amount of heat remained in the one column(s) immediately before shifting from desorption to adsorption stage to the other column(s) immediately before shifting from adsorption to desorption stage where the preheat the adsorbent and then reversing the stages. The evaporator preferably comprises heat transfer tubes for passage of a heating medium on a utilization side arranged in multi-stage, evaporating plates holding the refrigerant liquid in which each stage of the tubes are partly immersed, and overflow members for adjusting the liquid level, whereby evaporating ebullition occurs briskly.
