    Abstract: A system and method for crowd-sourced environmental system control and building maintenance includes a server for providing selective access to building occupants and managers. Users are permitted to generate building reports in the form of (i) thermal reports using a thermal report module, and/or (ii) maintenance reports using a maintenance report module. The reports are each geo-located to locations within the building, and are then captured, stored, and aggregated at the server. The aggregated reports are sorted according to their geo-locations and comfort rules are used to (i) permit a manager at a client computer to access the server to respond, and/or (ii) automatically respond and assign a response status to particular reports. An inspection checklist interface is generated and populated to display a list of preventative maintenance tasks, each of the tasks being user-selectable to designate completion, with the updated status of the reports being stored at the server.

    Abstract: An air conditioning capacity presenting system presents a capacity of an air conditioning apparatus including at least one outdoor unit, at least one indoor unit, and a connection pipe that connects the outdoor unit and the indoor unit. The air conditioning capacity presenting system includes first acquisition unit, a measurement unit, a second acquisition unit, and a capacity calculating unit. The first acquisition unit acquires outdoor unit capacity information, which is a rated capacity of the outdoor unit or information related to the rated capacity. The measurement unit measures power consumption of the outdoor unit. The second acquisition unit acquires an outside air temperature, which is a temperature of air around the outdoor unit. The capacity calculating unit obtains a calculation value of the capacity of the air conditioning apparatus based on the outdoor unit capacity information, the power consumption, and the outside air temperature.

    Abstract: Provided are embodiments for a wireless gateway device for a heating, ventilation, and air conditioning (HVAC) system for providing sensor information and sensor communication over relay-controlled power line. The wireless gate device includes an input/output (I/O) interface, a communication unit, and a controller. The controller is communicably coupled with the I/O interface and the communication unit. The controller is configured to receive operational data from at least one of one or more sensors and a thermostat of the HVAC system over the power line. The controller is also configured to control one or more components of the HVAC system based on the operational data associated with the HVAC system. The controller can also transmit the operational data to a remote server.

    Abstract: A room unit for an HVAC system is disclosed. The system includes a housing for installing the room unit on a wall of a building; a connection means to connect the device to the HVAC system; a controller being arranged on a first printed circuit board; and at least one temperature sensor to measure the temperature of ambient air, whereby the at least one temperature sensor is arranged on a frontside of a second printed circuit board. In addition, the second printed circuit board protrudes from the first printed circuit board, especially in a direction perpendicular to the first printed circuit board. Still further, the second printed circuit board is arranged such that a backside of the second printed circuit board is in physical contact with an inner surface of the housing.

    Abstract: The purpose of the present invention is to provide a vehicle air conditioning system and a control method of the vehicle air conditioning system which enable detecting leaks of flammable refrigerant without requiring a separate sensor. This vehicle air conditioning system is provided with: a refrigeration cycle for cooling (23); a heat pump cycle for heating (33); a refrigerant that is very flammable, has an explosive range near room temperature, and circulates in the refrigeration cycle for cooling (23) and the heat pump cycle for heating (33); an outside temperature sensor (44) which detects the outside temperature; a pressure sensor (49) which detects the refrigerant pressure; and a control device which calculates the refrigerant density, which is the density of refrigerant, on the basis of the outside temperature and the pressure, and determines whether or not the refrigerant density has fallen below a prescribed threshold value which is based on the amount of sealed refrigerant, the total volume in the refrigeration cycle for cooling (23) and in the heat pump cycle for heating (33), the volume of the vehicle cabin, the standard density of the atmosphere, and the explosive limit of the refrigerant.

    Abstract: The ionizer feedback control converts high-voltage signals to feedback signals to monitor the corresponding high-voltage signals and compares the feedback signals to a first specification to determine whether the feedback signals are within the first specification. The ionizer varies a frequency and a duty cycle of a digital signal to control an excitation signal for a step-up transformer and modulates the frequency and the duty cycle of a step-up transformer output voltage to consistently maintain the feedback signals within the first specification and maintain the high-voltage signals within a second specification to generate consistent ion concentrations over a range of electrical signal inputs. The microprocessor calculates and reports high-voltage signals, and ion concentrations based on feedback signals. The microprocessor monitors concentrations of Volatile Organic Compounds (VOCs) in an airflow serving the ionizer and adjusts the high-voltage signals and ion concentration when VOC concentrations are above a threshold.
