| 20120248213 | Hyper-Condensate Recycler - A system for heating a facility is provided. The system includes a first inlet from a district heating system. A heating system is arranged having a condensate outlet. A hyper-condensate recycler is provided having a second inlet coupled to the condensate outlet and a third inlet coupled to the first inlet. The hyper-condensate recycler includes a first outlet. A separator having a fourth inlet is coupled to the first outlet, the separator further having a second outlet fluidly coupled to the first inlet. | 10-04-2012 |
| 20150300656 | SUPPLY PIPE AND PIPE SYSTEM FOR THERMAL ENERGY NETWORK BASED ON BILATERAL HEAT TRADE - Provided are a supply pipe and a pipe system that may simultaneously accumulate a plurality of thermal energies having different temperatures in a thermal energy network based on bilateral heat trade. The supply pipe is driven by an operation system, supplies a thermal energy to a user or a heat source, and includes an external pipe, at least two internal pipes that are disposed inside the external pipe and accumulate a thermal energy having a predetermined temperature, and a filler that fills the external pipe inside which the at least two internal pipes are disposed, wherein the at least two internal pipes have thermal energies having different temperatures. | 10-22-2015 |
| 20150300659 | System of Boiler Equipment and the Components and Structural Elements of Such a System - Body elements of a boiler installation form, in the top part thereof, at least one channel for receiving pipelines and/or wires, the pipelines and/or wires connecting electrical equipment of the units. A distributing heat-carrier collector is laid along the length of the body and is comprised of component elements, the number of which corresponds to the number of units through which a heat-carrier passes. Pumps of such units are installed vertically on uppermost horizontal cross-pieces of the body, with an engine on top. This makes it possible to increase the compactness, ease of repair, and ease of replacing the entire system or individual units thereof, to unify such units, and also to undertake the installation of the units without the additional use of special equipment. | 10-22-2015 |

| 20090194603 | INTEGRATED HEATING SYSTEM - An integrated heating unit operates in a first heating mode, in which the heat of combustion gases is transferred to return air, and a second heat recovery mode, in which the heat of exhaust air is transferred to fresh air. The heating unit of the present invention utilizes the same heat exchanging unit and fans to transfer the heat from the combustion gases to the return air and to transfer heat from the exhaust air to the fresh air. The exhaust air is recovered from a select group of rooms, e.g. kitchens and bathrooms. A secondary heater can also be provided in the integrated unit in the form of a fireplace for providing an alternate or an additional source of the combustion gases. | 08-06-2009 |
| 20110174890 | FURNACE VENT TERMINATION - One aspect of the disclosure provides a termination for use with a furnace. The termination, in one embodiment, includes a face plate including an exhaust region and an air supply region, the face plate having a front surface and an opposing back surface. The termination, in this embodiment, further includes an exhaust termination portion extending from the back surface in the exhaust region, the exhaust termination portion capable of engaging a terminal end of a variety of different size exhaust conduits associated with a furnace. The termination, in this embodiment, further includes an opening extending through the face plate in the exhaust region, the opening aligned with the exhaust termination portion. | 07-21-2011 |
