The disclosure provides an HVAC data processing and communication network and a method of manufacturing the same. In one embodiment, the HVAC data processing and communication network includes a system device, a subnet controller and a user interface. The system device is configured to receive a control message from a data bus and operate according to a control setting communicated thereby. The system device is further configured to generate an alarm message in the event that the device enters an alarm state in response to an alarm condition. The user interface is configured to receive the alarm message and display alarm information in response to the message. The subnet controller is configured to provide operational control of the system device via the control message. The operational control is decoupled from the alarm message.

Alarm and diagnostics system and method for a distributed- architecture heating, ventilation and air conditioning network

An HVAC data processing and communication network includes a first subnet and a second subnet. The first subnet includes a first demand unit, a first comfort sensor and a first subnet controller. The second subnet includes a second subnet comprising a second demand unit, a second comfort sensor and a second subnet controller. The second subnet controller is configured to control an operation of the first subnet.

A vehicle air-conditioner provided with an inside air-conditioning unit introducing at least one of inside air and outside air, adjusting the state of the introduced air, and blowing it out into the vehicle compartment, where an air-conditioning electronic control device judges if window glass is liable to fog up based on a window glass surface relative humidity near the window glass in the compartment (degree of ease of fogging). When it is judged that the window glass is liable to fog up, the inside air-conditioning unit is controlled to prevent the window glass from fogging up in defrost control, while when it is judged that the window glass is resistant to fogging, the inside air-conditioning unit is controlled to introduce at least inside air into the compartment.

Vehicular air-conditioner

One aspect provides of this disclosure provides a flush wall mounting system for an electronic controller. This embodiment comprises a housing for receiving electrical components therein and having a front panel and a back panel coupled to the front panel. The back panel has a raised portion extending therefrom. This aspect further includes a mounting plate removably couplable to the back panel of the housing and has front and back sides. The front side includes a flange around a perimeter thereof and has a recess formed therein configured to receive the raised portion of the back panel therein. The recess forms a raised portion extending from the back side and configured to be receivable within an opening in a wall. A method for manufacturing the mounting system is also provided.

An air passage opening/closing device includes a film member for opening and closing an opening of an air passage of a case One end of the film member is fixed to a fixing portion on an outer periphery of the opening of the air passage, and the other end thereof is connected to a film winding shaft A moving member movable by rotation of a drive shaft is provided on the opening, and the film winding shaft is moved while being rotated by the movement of the moving member, so that the film member at the other end side is wound around and unwound from the film winding shaft Accordingly, when the air passage is opened and closed by the film member, sliding friction can be prevented from being generated between the film member and the case

Air-passage opening/closing device

An upper opening portion (74, 75) and lower opening portion (76, 77) are arranged in a door body (13 b , 14 b) located below a side window (13 a , 14 a), and an air conditioning unit (15, 16) is arranged inside the door body (13 b , 14 b), and a rotary position of a scroll casing (62, 63) of a blower (56, 57) is selected so that air can flow from the lower opening portion (76, 77) to the upper opening portion (74, 75) at the time of air-cooling and air can flow from the upper opening portion (74, 75) to the lower opening portion (76, 77) at the time of heating

Air conditioner for vehicle use

An engine cooling apparatus suitable for use in a vehicle shortens engine warm-up time without decreasing the heat-radiation capacity of a radiator. A shroud is disposed between a radiator and a water-cooled engine. A first air passage for blowing air toward the engine and its auxiliaries is formed in the upper side of the shroud, and a second air passage for discharging air having passed through the radiator to outside the engine compartment is formed in the lower side of the shroud. Accordingly, air is prevented from directly striking the engine and from passing around to the upstream side of the radiator through gaps between the walls of the engine compartment and the radiator. Thus the engine warm-up time is shortened without reducing the heat-radiation capacity of the radiator.

Engine cooling apparatus

An automotive air conditioner comprises an offset blower for blowing an air, an evaporator is centrally disposed within a dashboard and receives the air from below, and a heater approximately horizontally disposed above the evaporator The evaporator inclines downward along the direction of the air flow A plurality of condensed water guide plates are provided under the evaporator so as to allow a condensed water smoothly flow on the surface of each guide plate and is discharged from the evaporator through a condensed water drain pipe

Automotive air conditioner

A centrifugal blower is provided with a casing which defines a spiral duct and a centrifugal fan which is rotationally provided within the casing. The centrifugal fan has a bottom plate and a plurality of blades which are equally spaced along the periphery of the bottom plate. The plurality of blades extends parallel to the rotational axis. The duct is arranged to reduce the size of a low velocity air flow zone which is generated in an upper radially outer region in the spiral duct. The low velocity air flow zone, which appears in an upper radially outer region in the air duct, is reduced to reduce surging in the blower.
