A drying furnace device of a gasifier capable of automatically adjusting temperatures includes a gasifier and a drying furnace assembly. The gasifier includes a furnace wall. A top of the furnace wall is provided with a coal inlet, a top side of the furnace wall is provided with a gas outlet, and an outside of a bottom of the furnace wall is provided with a cooling layer. The drying furnace assembly includes a drying-furnace feeding device, a temperature detection device and an automatic control valve. The drying-furnace feeding device is detachably installed inside the coal inlet. The automatic control valve is detachably installed at one end of a coal gas outlet away from the furnace wall. The temperature detection device is installed at an outside of a middle of the furnace wall, and the temperature detection device is connected with the automatic control valve through a heat-resistant hose.

A liquid-cooling device includes multiple water blocks and at least one connection tube. Each of the water blocks has a water incoming end, a water outgoing end and a water-receiving space in communication with the water incoming end and the water outgoing end. The connection tube is disposed between each two water blocks. Two ends of the connection tube are respectively connected with the water incoming end of one of the two water blocks and the water outgoing end of the other water block, whereby the water-receiving spaces of the two water blocks communicate with each other via the connection tube. The connection tube has at least one bellows section between two ends of the connection tube. The liquid-cooling device solves the problems of the conventional liquid-cooling device that when the water block is welded, thermal deformation is produced to cause tolerance and the manufacturing cost is higher.

On the screen of a display unit, period border lines are displayed. The period border lines divide hours (for example 24 hours) for a user's desired one day into a plurality of periods and present line segments movable on the screen in a predetermined direction. Each of the line segments acts as a border lien between mutually adjacent periods. On the screen, target temperatures which are set for the respective periods are also displayed. Dragging the period border liens (K1 to K4) so as to move on the screen makes it possible to move a start time and a stop time of mutually adjacent periods are changed simultaneously. In addition to this change, target temperatures which were set before the change are reset for changed periods.

A thermostat comprises a hollow body containing a thermally responsive material, and a force transmitting member affixed to the body by an over-molded portion.

An air conditioning system includes a heat pump unit including a radiator usable with a refrigerant, a gas furnace unit including a heating section arranged to heat passing air, a blower arranged to generate an air flow that passes through the radiator and the heating section, a first temperature sensor provided in a room, and a controller configured to control each action of the heat pump unit, the gas furnace unit, and the blower. The temperature sensor detects an indoor temperature in the room. The controller causes the gas furnace unit to operate as a heat source unit when a difference value obtained by subtracting the indoor temperature from a set temperature is equal to or greater than a first threshold at startup, and causes the heat pump unit to operate as a heat source unit when the difference value is less than the first threshold at startup.

A temperature-controlling measure for a hydrogenation slurry bed reactor has three control points that are set from low to high: cold hydrogen is injected automatically when the system reaches control point 1; cold oil is injected automatically when the system reaches control point 2; each pressure relief is opened automatically when the system reaches control point 3. The pressure relief point is set before and/or after the circulation pump of the reactor if internal circulation is set in the reactor; the pressure relief point is set at the reactor bottom if the internal circulation is not set; at least one pressure relief valve is set at each pressure relief point.
