A method for regulating a conditioning apparatus includes a heating/cooling device and a ventilation device which generates a flow of air toward the heating/cooling device in order to direct it toward a room to be conditioned. The method includes the step of switching on the conditioning apparatus in a switch-on instant, the step of activating the heating/cooling device and the ventilation device, the step of determining a commutation instant, and the step of driving the ventilation device so that, until the previously determined commutation instant, the ventilation device is stationary or rotates at a maximum speed equal to a certain speed of the ventilation device.

The present disclosure relates to the field of air conditioning technology. In particular, it involves an air control method for air handler unit.

An air conditioner may include a casing having an inner air flow space defined therein and an entrance defined in one of a first side plate or a second side plate, a heat exchanger and a fan disposed between an outdoor air inlet body and an air outlet body in an air flow direction of the casing, a heater module inserted through the entrance into the inner air flow space, a handle mounted on one side face among both side faces of the heater module, one side face of the both side faces being closer to the entrance than the other side face thereof, a pair of guide brackets installed in the casing to slidably guide the heater module, and a door module that opens and closes the entrance. The door module may be configured to contact the handle to press the handle in a direction away from the entrance.

A forced airflow drying apparatus includes a body including a pair of air inlets to receive inlet air which is channeled to an upstream side of a filter unit, a pair of body airflow generators to generate a first forced airflow, each body airflow generator having a first end and a second end, where the first end of each body airflow generator is opened to a downstream side of the filter unit, a pair of thermoelectric devices configured to control a temperature of the first forced airflow, and a first air outlet, in communication with the second end of each body airflow generator, to receive the forced airflow from the body airflow generators and to expel the forced airflow out of the body. The forced airflow drying apparatus further includes a bar and a drive apparatus configured to movably drive the bar relative to the body, the bar including a second pair of airflow generators to generate a second forced airflow, a pair of resistance heaters to control a temperature of the second forced airflow prior to being expelled from the second air outlet, and a second air outlet to expel the second forced airflow from the bar.

Disclosed are an air duct assembly and a fan heater applying in the air duct assembly, which includes a volute tongue positioned in the volute forms an air duct with the volute. The air duct is configured with an air inlet and an air outlet. A cross-flow wind turbine positioned in the air duct introduce the airflow into the air duct from the air inlet, and blow out the airflow in the air duct through the air outlet. The volute includes a first volute tongue member, the size of the angle between the line connecting the root portion M of the first volute tongue member to the axis O of the cross-flow wind turbine and the line connecting the root portion N of the second volute tongue member to the axis O of the cross-flow wind turbine on the same cross-section is from 110° to 170°.

An apparatus and method to selectively create a heat transfer effect and sensation of cooling within bedding on a mattress. A programmable application is accessible on a wireless network and is programmed to provide appropriate settings to attain changes over time of a space within bedding that pertain to at least one of heating the space and realizing a cooling sensation within the space. A wireless receiver is configured to receive commands in a wireless manner that are indicative of the appropriate settings provided by the programmable application to effect changes over time of the space within the bedding attributed to heat transfer with respect to the at least one of heating the space and realizing a cooling sensation within the space. The heat transfer occurs as a result of fluid flow either within a mattress or within space in bedding over the mattress.

An air supply device with air refreshing and insect repellent function include a housing, which comprises: an air duct unit supported inside the housing having a hollow body defining an air channel; a centrifugal fan received inside the air duct unit; two main air inlets arranged at two opposite sides of the housing; an air outlet arranged at a top portion of the housing and channeled through with the air channel inside the air duct unit at a front side of the housing perpendicular to each of the main air inlets; an auxiliary air inlet arranged at a rear side of the housing opposite to the air outlet; an auxiliary component, which is an aromatherapy component or a mosquito repellent component, connected to the housing at the auxiliary air inlet; and an optional heating component detachably connected to the housing at the main air inlet.

A heating apparatus includes a housing, and a virtual heating module and a heating module installed inside the housing. The heating module includes at least two heating elements respectively installed on different sides of the housing, and each heating element is provided with a warm air vent facing a front side of the housing, and each heating element is in strip shape and configured at a corresponding side of the housing. The heating module is divided into several heating elements distributed at different positions of the virtual heating module to disperse the heat sources so as to increase the heating area, thereby making the user feel comfortable and warm.

A heating device including: a housing having an opening and surrounding an interior space. A fan is arranged in proximity to the housing. A heating element is arranged in the housing, and a heat distribution element arranged in the housing and in proximity to the heating element. The heating element is adapted to generate heat. The heat distribution element is adapted to transfer the heat generated by the heating element to air in the interior space, and the fan is adapted to provide a flow of air through the interior space of the housing such that the air is heated. The heated air leaves the housing through the opening.
