Example embodiments of the present disclosure relate to a control system for controlling an HVAC device where the control system includes a temperature sensor that provides a signal indicative of a temperature associated with the HVAC device, an orientation sensor that provides a signal indicative of an operating orientation of the HVAC device, and control circuitry that receives the temperature signal and the orientation signal from the orientation sensor. The control circuitry selects an operating thermal control set point from a plurality of stored thermal control set points based at least in part on an orientation signal, determines a temperature sensor input based on the temperature signal and compares the temperature sensor input to the operating thermal control set point, and operates the HVAC device based at least in part on that comparison.

An air handling system includes an fan system and an outdoor system. The fan system and the outdoor system are connected by a refrigeration circuit. The fan system includes a dehumidification system.

Provided are a method and device for controlling electric heating of an air conditioner compressor. The method may include: first request information is transmitted to a corresponding database server at an interval of a second preset duration, as to acquire weather forecast data of an area where an air conditioner is located within an upcoming third preset duration; the weather forecast data returned by the database server is received and stored in a built-in database of the air conditioner; it is monitored to learn that a shutdown duration of the air conditioner compressor exceeds a first preset duration, as to acquire the weather forecast data stored in the built-in database of the air conditioner; and a control strategy is generated according to the weather forecast data, to control the air conditioner compressor to start and stop electric heating.

An air conditioner may include a heat exchanger having a first cooling coil and a second cooling coil inclined toward each other, an inlet formed between a lower end of the first cooling coil and a lower end of the second cooling coil to allow air to pass through, an inside air duct through which air introduced to the inlet flows, an air supply duct through which the air passing through the heat exchanger flows, a fan causing air passing through the heat exchanger to flow, and a temperature sensor sensing a temperature of the air introduced into the heat exchanger. The heat exchanger includes a plate positioned between the first cooling coil and the second cooling coil. The plate may have a sensor insertion hole into which the temperature sensing device is inserted. By measuring the temperature of the air introduced into the heat exchanger, more accurate control information may be provided.

The present disclosure discloses a ventilation management system for outdoor products, a sleeping bag, and a chair. The ventilation management system for outdoor products comprises a ventilation chamber, a temperature adjustment device, and a mobile power supply. The ventilation chamber is flexible and integrally arranged on the outdoor products, and a side of the ventilation chamber configured to face a human body comprises a plurality of air outlets. The temperature adjustment device comprises a fan and a control module, and the temperature adjustment device is electrically connected to the mobile power supply. The temperature adjustment device is configured to supply cool or warm air to the ventilation chamber, and the cool or warm air is configured to be blown onto the human body via the plurality of air outlets after entering the ventilation chamber. Each of the sleeping bag and the chair comprises the ventilation management system.

A flue collector box for a furnace having a cooling coil, a heat exchanger, and an inducer blower includes a housing having an interior chamber in fluid communication with the heat exchanger such that condensation generated in the heat exchanger flows to the interior chamber of the housing. A valve is connected to the housing and includes a pair of lips defining a fluid passage through the valve in fluid communication with the interior chamber. The lips have an open condition allowing condensation to exit the valve when the inducer blower is deactivated. The lips have a closed condition forcefully engaging one another when the inducer blower is activated to prevent condensation from exiting the valve.

In one or more embodiments, a displacement induction environmental sanitizing control system for controlling the environment in a room is provided. The system includes a housing having a supply air intake configured to receive a supply of pressurized outside air, a room air intake configured to receive air into the housing from the room, and a conditioned air outlet configured to output conditioned sanitized air into the room from the housing. The housing has an airflow path from the room air intake and the supply air intake to the conditioned air outlet. A conditioning element is configured to adjust temperature of air in the airflow path. A sanitation element is configured to sanitize air in the airflow path.

A system for controlling the circulation of air in an indoor area of a structure including a door or window. A fan for circulating the air within the indoor area is combined with a first sensor for sensing a temperature of a surface of an object in the indoor area. A controller controls the operation of the fan based on the surface temperature sensed by the first sensor, and also regulates a radiant heater for heating the surface or the object. The controller may also or alternatively be adapted for controlling the fan based on an indication that it is raining external to the structure, an HVAC unit, or a dehumidifier. Related methods are also disclosed.

The present invention relates to hetro dehumidifier for controlling the humidity in a room. The hetro dehumidifier controls the humidity by using combination of heaters and air conditioner. The dehumidifier of the present invention includes heaters, air conditioner, air circulation fans, humidity sensors, temperature sensors, air filters, digital display & front panel keys, microcontroller and IR Remote control.

An apparatus is used with supplied power for treating air in an environment. A housing is mobile in the environment and has an intake and an exhaust. At least one prime mover disposed in the housing between the intake and the exhaust is operable to move the air in the environment through the housing from the intake to the exhaust. At least one ultraviolet light source disposed in the housing is connected in electrical communication with the supplied power and is configured to generate ultraviolet radiation in at least one a portion of the housing through which the moved air passes from the intake to the exhaust. At least one permeable barrier disposed in the housing is configured to impede the moved air flow therethrough up to an impedance threshold. The at least one permeable barrier is connected in electrical communication to the supplied power and being heated to a surface temperature.
