A method for a refrigeration system includes applying, by a gas cooler of the refrigeration system, a first cooling stage to refrigerant circulating through the refrigeration system load. The method further comprises applying, by a heat exchanger located downstream from the gas cooler, a second cooling stage to the refrigerant, wherein the second cooling stage removes heat from the refrigerant, and applying, by the heat exchanger located downstream from the gas cooler, the heat removed during the second cooling stage to a water heating system operable to heat water.

The panel of insulating material (30) being placed above the bottom panel (20) and with the heating device (50) comprised between the top panel (10) and the panel of insulating material (30) and wherein connecting means (100) configured in such a manner as to exert a mechanical action according an approaching direction of the top panel (10) to the bottom panel (20) in such a manner as to keep the elements of the module stacked on each other, said connecting means being further configured in such a manner to be movable in such a manner that, as they are removed, one or more of said elements constituting the module are disassemblable each other.

A heating system is configured to optimize the speed and accuracy of the system in achieving various ambient air temperature setpoints, by modulating the heated water supply water setpoint to optimize the slope of the system's response curve. Optimized response curves are automatically determined by analyzing differences between ambient air temperatures over time in response to modulated supply water temperatures as they are reset upward or downward to achieve response times prioritized for improved occupant comfort. The controller of the heating system calculates a temperature slope, and adjusts the supply water setpoint to increase/decrease the speed of ambient temperature rise to achieve a desired slope.

Provided is a self-assembly hot water mat capable of extending through assembly. A self-assembly hot water mat capable of being assembled with other self-assembly hot water mats, having four sides, and including a path for circulating hot water includes a plurality of hot water passages formed in the self-assembly hot water mat to provide a plurality of hot water flow paths, an inlet formed at each of the four sides, through which hot water flows in, and an outlet formed at each of the four sides and paired with the inlet, through which hot water flows out.

A hydronic floor heating system as it relates to an HVAC apparatus, approach and system. Aspects of the present system and approach may include a radiant floor optimization mode, low floor temperature in vacation mode, modifying a 300 Hz, or so, reading principle base on implementation of Pseudo-random jittering of a reading event improving short-term accuracy of the individual readings, and a combination of hardware and software filters for using thermal sensors with extended cable length.

A support structure for a heating or cooling system includes a plurality of projections designed to be capable of retaining one or more thermal elements positioned adjacent thereto. The projections are positioned so as to form a first set of substantially parallel undulating channels, each channel having one of the projections forming at least a part of the inner radius of each undulation, with each projection having a recess formed in a side wall thereof facing said channel. The undulations of the channel ensure that a thermal element positioned in the channel will make contact with the projections each time it has to bend around one, without requiring spacing of the projections to squeeze the thermal element. The thermal element can thus be held securely without any play (unwanted lateral movement) in a channel that is slightly wider than the thermal element. Recesses in the channels at the contact points also restrict movement in the vertical direction, thus preventing the thermal element from popping out of the channel, while not requiring any restriction narrower than the thermal element.

Described herein is a composite panel that includes a first layer made from an electrically non-conductive material. The composite panel also includes a resistance heater printed onto the first layer and a capacitive sensor applied onto the first layer. The capacitive sensor is operably coupled with the resistance heater. The composite panel additionally includes a second layer adjacent the resistance heater and the capacitive sensor. The resistance heater and the capacitive sensor are positioned between the first layer and the second layer. Furthermore, the second layer is made from an electrically non-conductive material. The resistance heater is configured to generate heat at least partially in response to input sensed by the capacitive sensor.

Some deck or patio areas constructed of payers mourned on adjustable pedestal supports must remain snow and ice free on their top surfaces. The pedestal-mounted paver heating system is designed to allow easy installation of electric heating cable that is positioned against the bottom surface of pavers so that heat generated by the cable is efficiently transferred up into the payers to raise their temperature enough to prevent the accumulation of snow and ice on their top surfaces.
