An air-conditioning unit is provided, comprising: an input vent for receiving return air; an intermediate vent; an output vent; a blower fan proximate to the input vent for moving the return air from the input vent to the intermediate vent; and an air-conditioner coil between the intermediate vent and the output vent including an active portion including one or more operational air-conditioning coils that receive a first portion of the return air from the intermediate vent, for circulating a coolant, condition the first portion of the return air by heat exchange with the coolant to create conditioned air, and pass the conditioned air to the output vent, and an inactive portion that does not circulate coolant and passes a second portion of the return air as unconditioned air to the output vent, wherein the conditioned air and the unconditioned air pass through the output vent as supply air.

A device (1) for disinfecting air by combustion has a primary inlet (10) that sucks primary air into a combustion chamber (11) with a burner nozzle (12). The primary air flows along a flow path into a mixing chamber (13) arranged along the flow path after the combustion chamber (11). The primary air (L1) is heated to a first temperature. The mixing chamber (13) has an outlet (14) and at least one secondary inlet (15). Secondary air can be sucked (L2) into the mixing chamber (13) through the inlet (15). The mixing chamber (13) produces a mixed air (L3) of a third temperature of at least 100° C. from a mixing of the primary air (L1) and the secondary air (L2). The mixed air (L3) is held in the mixing chamber (13) for a predetermined residence time, and discharges the mixed air (L3) along the flow path through the outlet (14).

An air handling unit has a blower assembly, a first interior zone, and a second interior zone and the blower assembly physically separates the first interior zone from the second interior zone. A method includes providing a cabinet configured to receive a blower assembly, inserting a blower assembly into the air duct, and closing a cabinet door of the cabinet, wherein upon closing the cabinet door, the primary air flow path from a location within the cabinet downstream of the blower assembly to a location within the cabinet upstream of the blower assembly is through a blower housing of the blower assembly. A blower assembly has a blower housing comprising at least one air inlet and at least one air outlet and a blower deck extending from the outlet, wherein the blower deck comprises at least one substantially flat component having a substantially orthogonal wall extending from the flat component.

Provided is an air-cooling/heating switching type air-conditioning system which includes multiple indoor units, and includes: a receiving section configured to receive information regarding an operation state of air-cooling or air-heating from one indoor unit of the multiple indoor units; a switching section configured to switch the operation state of the air-cooling or the air-heating according to the received information; a control section configured to make such control that operation is performed in cooperation with the one indoor unit in a case where the operation state is switched; and a transmission section configured not to transmit, in the case where the operation state is switched, information on the operation state to other operating indoor units of the multiple indoor units and to transmit an operation instruction to equipment placed in spaces identical to those of the other indoor units to adjust temperatures.

An air-conditioning unit is provided, comprising: an input vent for receiving return air; an intermediate vent; an output vent; a blower fan proximate to the input vent for moving the return air from the input vent to the intermediate vent; and an air-conditioner coil between the intermediate vent and the output vent including an active portion including one or more operational air-conditioning coils that receive a first portion of the return air from the intermediate vent, for circulating a coolant, condition the first portion of the return air by heat exchange with the coolant to create conditioned air, and pass the conditioned air to the output vent, and an inactive portion that does not circulate coolant and passes a second portion of the return air as unconditioned air to the output vent, wherein the conditioned air and the unconditioned air pass through the output vent as supply air.

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.
