Detailed Description
To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the embodiments of the present invention are combined to clearly and completely describe the technical solution in the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The process air conditioner sucks air from a return air inlet through a fan, cools and dehumidifies the sucked air through a surface air cooler, heats the cooled and dehumidified air through a heater, and humidifies the cooled and dehumidified air through a humidifier. The cold and heat source medium detection device is designed for heat source medium steam and cold source medium chilled water used by the process air conditioner, can help to find out cold and heat source parameter abnormity in time, remind related personnel to maintain, and help to reduce surface cooling section cold consumption and realize humidification section isothermal humidification.
Referring to fig. 1 to 2, the process air conditioner cold and heat source medium detection device of the present embodiment includes a heating steam flow meter 3, a humidifying steam flow meter 4, a chilled water flow meter 5, a chilled water temperature sensor 6, a steam temperature sensor 7, a steam pressure sensor 8, a steam trap 9 and a pressure reducing valve 10 which are connected to and controlled by a PLC controller 2 matched with the process air conditioner 1;
a humidifying steam pipeline is provided with a humidifying steam flow meter 4, a steam temperature sensor 7 and a steam pressure sensor 8 which are respectively used for detecting the flow, the temperature and the pressure of humidifying steam, and a pressure reducing valve 10;
