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.

Some deck or patio areas constructed of pavers mounted 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 pavers to raise their temperature enough to prevent the accumulation of snow and ice on their top surfaces.

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. Further, the composite panel includes a second layer adjacent the resistance heater, the resistance heater being positioned between the first layer and the second layer. The second layer is made from an electrically non-conductive material.

A panel, for retaining a heating or cooling tube relative to a substrate, has a standoff extending from a primary flap, wherein the standoff includes a tube contacting surface. A lateral fold extends from the standoff and includes a jaw having a tube retaining surface, wherein the tube contacting surface and the tube retaining surface are located to define a tube retaining channel in a closed position of the jaw. The panel can be formed of a single piece of sheet metal, wherein the sheet metal and configuration of the panel bias the jaw to the closed position.

A temperature control system for controlling the temperature of a room and a composite element for a temperature control system.

A heating panel including a thermally conductive (e.g. metal) layer, a laminar heating element disposed over a framing-facing side of the thermally conductive layer, an insulation layer disposed over the laminar heating element, and a room-facing surface layer disposed over at least the room-facing side of the thermally conductive layer. A method for heating a room may include installing at least one heating panel on a ceiling of the room and providing power to the heating element to generate heat that radiates into the room. The panel may be part of a heating system including a controller, such as a thermostat, for regulating power to the heating panel. A plurality of heating panels or a plurality of heating zones in one or more of the panels may be independently controllable.

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.

A panel comprising a heat providing layer is presented. The panel includes panel coupling means arranged for coupling the panel to adjacent panels. End panel grooves, at least partly extending between first and second opposite longitudinal sides of the panel, are arranged in the end panel coupling means of the panel. In order to provide heat, electrical end connectors are arranged in the end panel grooves of the panel. The electrical end connectors are arranged for being electrically connected to the heat providing layer of the panel, at least partly including an electrically conductive material, and at least partly protruding from the one or more end panel grooves, thereby providing an electrical connection between the heat providing layer of the panel and a corresponding heat providing layer of at least one adjacent panel coupled to the panel.

A hydraulic module control system of a floor heating multi-split air conditioner and a control method of the hydraulic module control system. The system includes: a plurality of temperature controllers, in signal connection with the hydraulic module, and configured to set a set temperature in each room and an operation mode of the hydraulic module; and a control module, in signal connection with the hydraulic module, and configured to: set preset water outlet temperature values under the different operation modes of the hydraulic module; and control the hydraulic module to operate according to received operation modes set by the temperature controllers and preset water outlet temperature values corresponding to the set temperatures, and control the operation mode of the hydraulic module according to a comparison result of an outdoor ambient temperature and a first temperature preset value when both a cooling operation mode and a heating operation mode are received.
