Abstract: The present invention relates to a split type cold and warm air conditioner for solving problems of insufficient performances and inconvenience in use. The split type cold and warm air conditioner includes an air conditioning system having an outdoor unit and an indoor unit. The outdoor unit includes a first heat exchanger, a second heat exchanger, a first fan, a compressor, an accumulator and a capillary tube. The indoor unit includes a third heat exchanger, a fourth heat exchanger and a second fan. A first refrigerant circulation loop and a second refrigerant circulation loop can be constituted by using pipelines and solenoid valves to connect the above-mentioned components. The invention provides both high performances for cold and warm air functions.

Abstract: This invention provides portable stands for cell phones/tablets/mobile electronic devices having at least one receptacle for power and/or an earphone/headset. The portable stand includes a support leg for supporting the electronic device on a surface, the support leg having a proximal end and a distal end, the distal end being configured to engage with a surface on which the mobile device is being supported. The stand includes a clasping means for releasably attaching the support leg to the electronic device. The clasping means extends from the proximal end of the support leg and is configured to be engaged with a connector plug inserted into the receptacle of the electronic device.

Abstract: A variable-damper multi-function heat pump air conditioner includes a housing defining a lower chamber and an upper chamber with a respective indoor-facing/outdoor-facing inlet and indoor-facing/outdoor-facing outlet, a lower damper and an upper damper respectively mounted in the lower chamber and the upper chamber, and an evaporator and a condenser of an air-conditioning system respectively mounted in the lower chamber at two opposite sides so that the air conditioner can run under the mode of cooling function in hot weather, the mode of heating function in cold weather, the mode of indoor-air and outdoor-air exchanging with/without cooling function in hot weather, the mode of indoor-air and outdoor-air exchanging with/without heating function in cold weather, the mode of one-fan-operation-only energy-saving quiet indoor-air and outdoor-air exchanging function, or the mode of dehumidifying with heating function in cold and humid weather by means of selectively controlling the operation of fans of the air-con

Abstract: A movable multi-functional air-conditioner equipped with wheels for high mobility is disclosed having a front chamber with an air inlet and an air outlet, an evaporator and a fan mounted in the front chamber, a rear chamber with an air inlet and an air outlet, a heater and a condenser mounted in the rear chamber, a front valve mounted in the air inlet of the front chamber, a rear valve mounted in the air inlet of the rear chamber, and an intermediate valve for controlling the air passage between the front chamber and the rear chamber so that the user to select hot mode, cold mode, dehumidifying mode, or simultaneous dehumidifying and drying mode by opening/closing the front valve, the rear valve, and the intermediate valve.

Abstract: A power-saving drying machine control method used in a drying machine is disclosed to include the steps of (a) enabling the temperature (or relative humidity) control unit of a central control unit to start working and to detect the temperature (or relative humidity) at the exhaust port of the drying machine through a temperature (or relative humidity) sensor once per a predetermined time unit when the temperature (or relative humidity) sensor detected a predetermined temperature (or relative humidity) value, and (b) driving the central control unit to shut off the drying machine when at least two temperature (or relative humidity) differences of at least three proceeding temperature (or relative humidity) values obtained from the exhaust port of the drying machine through the temperature (or relative humidity) sensor are within the precision of the temperature (or relative humidity) sensor.
