A temperature controlling device includes a setting controller, a gas valve, a burner, an inlet temperature sensor, a water meter, and an operational controller. User sets a desired temperature via the setting controller. The inlet temperature sensor senses an inlet temperature of water at an inlet of a pipe, and then operational controller calculates a difference between the inlet temperature and the desired temperature to get a total heat for heating water in a predetermined heating time and transfer the total heat into a total gas consumption, and controls the gas valve to supply gas to the burner with an amount of the total gas consumption in a predetermined heating time. After that, water should be heated to the desired temperature, and the operational controller controls the gas valve to decrease the gas supply for maintaining water temperature.

A heating system utilizing waste heat from illuminating device includes at least one illuminating device and a water supply device. The illuminating device has at least one light-emitting module, which has one side in contact with at least one heat-dissipation device. The heat-dissipation device and the water supply device are connected to each other via a pipeline. Water is supplied by the water supply device to the heat-dissipation device for directly absorbing heat that is transferred from the light-emitting module to the heat-dissipation device and accordingly cooling the heat-dissipation device. The heat-absorbed water is then delivered via the pipeline to a water reservoir for people to use. Thus, waste heat produced by the illuminating device is effectively converted into a usable energy source to be fully utilized.

An operating method in a heat pump hot water supply system of an indirect heating method by which an average COP during a water heating period can be improved and a risk of running out of hot water can be prevented from increasing. For a heat pump hot water supply system of the indirect heating method, a change in heat transfer efficiency of a second heat exchanger is estimated by using either or both of a tank water temperature and a temperature of a second refrigerant flowing through a water circuit. When the heat transfer efficiency is determined to be high, an operation switching unit raises an output of a heat source device. When the heat transfer efficiency is determined to be low, the operation switching unit lowers the output of the heat source device.

Novel method of using stored solar heat for water heating

Номер: US20220034521A1
Автор: Dipak R. Biswas
Принадлежит: Individual

A novel method is described for room heating using stored solar heat. Solar heat is stored in an insulated tank by using scrap and inexpensive heat absorbing or heat storing materials. Stored heat can then be extracted by air circulation for room heating. The temperature of the room air is controlled by a thermostat. When the room temperature drops below the set point on the thermostat, a circulating air pump turns on and extract the solar heat until the room temperature air reaches the desired set temperature. Once room temperature reaches the set point in the thermostat, the air circulation pump turns off.

Thermal gradient fluid header for multiple heating and cooling systems

Номер: US20160040893A1
Автор: Jeffrey A. Weston
Принадлежит: WESTON IP LLC

Apparatus and method for heating/cooling buildings and other facilities. An elongate pipe filled with water or other fluid medium forms a thermal gradient header having temperature zones that are progressively warmer towards one end and cooler towards the other. Multiple heating/cooling systems are connected to the header so as to draw fluid from zones that are closest in temperature to the optimal intake temperature of each system, and to discharge fluid back to the header at zones that are closest to the temperature to the optimal output temperature of each system, allowing each heating/cooling system to take advantage of the thermal output of other systems. The pipe forming the thermal gradient header may be routed back and forth in the facility to define a series of legs containing the different temperature zones. A boiler or other source may supply makeup heat to the thermal gradient header, and excess heat may be sent from the header to a ground field or other thermal reservoir for later use.

A water heater system includes a controller configured to integrate control of both recovery and recirculation operations of a recovery pump and a recirculation pump. As such, a separate device, installation location, and power source (e.g., available outlet) is not needed with the controller. Because a single controller is configured to control both recovery and recirculation operations, additional control functions are available. The controller may be in communication with an internal controller of the water heater and configured to receive an error notification upon abnormal operation of the water heater. The controller can stop recovery and recirculation operations in response to an error notification, unlike with traditional water heating systems which may otherwise continue to function. The recovery and recirculation operations are based on a setpoint temperature of the water heater such that changes made to the setpoint temperature will automatically adjust in the recovery and recirculation operations. 1.

The push pin bearing mechanism comprises a push pin that moves in a linear direction responsive to rotational movement of a motor gear that is coupled through a helical gear. Rotational movement of the push pin is prevented by a ball bearing assembly. Movement of the push pin is transferred to a manifold pin, which in turn, controls the manifold assembly. Because the push pin moves in a linear rather than a rotational fashion, erosion of the mated manifold pin is substantially reduced with respect to transitional approaches. 1.
