TH16184A3 - Centrally controlled variable air conditioning system - Google Patents

Abstract

1 page of the number 1 page summary of the invention The invention involved a centrally controlled variable air conditioning system, it was arranged in two main sections: the external installation and the internal installation, where the external fixture consisted of at least two compressors. Was designed to alternate It works to increase the pressure and forward the refrigerant to the condenser to lower the temperature.The refrigerant is then passed through the liquid tube to further enter the internal installation. For internal installation Provide refrigerant supply with electronic system. Serves to dispense substances Cooling to the indoor unit according to the load working properly By air conditioning system This variable modifier has a unique feature that it provides an internet connection, enabling real-time control of the system. It also has connections to the management system. Building Energy (BEMS) can be done through the BacNet protocol (BACNet), enabling control of the air conditioning system. Including other indoor systems Automatically

Claims (2)

Disclaimer (all) which will not appear on the advertisement page: page 1 of the number 2 disclaimers 1. The centrally controlled variable air conditioning system consists of 2 main parts: the installation part. And internal installation Details as follows The outdoor unit consists of at least two (1) direct current compressors where the pressure and temperature of the refrigerant are added. With the work by adjusting the speed of Compressor motor (1) to supply refrigerant according to the load. Then the refrigerant will be It is transferred through a liquid pipe to the condenser (2), where it looks like a complete tube panel for cooling by the condenser (2). Refrigerant supply control unit (3) Next, the internal installation consists of an electronically controlled dosing device (3). For distributing the required amount of refrigerant to the indoor unit (4) without the need for storage devices or resting along the pipeline. Where the evaporator (4) looks like an exchange tube panel The internal heating provides for installation of axial-flow fan coil (41) and evaporator coil (4). Each unit is wired in series. The special feature is that one condenser (2) can be connected to more than one fan coil (41) to allow independent temperature control and an Internet connection. Enabling remote control and monitoring The condenser (2) will be installed to Temperature sensors, humidity sensors, pressure sensors, as well as a power meter (21). The fan coil (41) is solely attached to the temperature sensor. By parameter It is returned to the control unit installed in the internal installation. In which the control unit will communicate Control commands and information Two-way to back-to-back protocol (BACNet) (5), where the back-to-back protocol (BACNet) (5) communicates to the web server, making it a customer or visitor traffic. The working status of the air conditioning system on the website in real time. Where this BACNet (5) communicates with the online network system connected to the central management system center. Building Energy (BEMS) (6) to control the operation of equipment and systems to be efficient, whereby customers or service users can adjust the order for use through the management Building Energy Management (BEMS) (6), which has the same output as directed by the device's remote control or controller, as it is connected to a syncronize control center. ) Between the Building Energy Management System (BEMS) (6) and the fan coil remote control (41) each page 2 of the number of 2 points. The Building Energy Management System (BEMS) (6) can also display the fault code status. Failure (Error Code) of operation can be transmitted via the back net (BACNet) (5) to enable relevant parties to resolve the problem promptly as well. 2. The centrally controlled variable air conditioning system according to claim 1, where the fully cooled condenser (2) is coated with aluminum-manganese.
