York Air Conditioning After-sales Q&A: How to measure the overall effect of an air conditioning system?
(1) Significance of measuring comprehensive effects: Measuring the comprehensive effect is to study the relationship between the changes in state parameters during the regulation process of the air conditioning system and the changes in indoor temperature. This can help identify the regularity of the air conditioning system, preparing for its continuous, stable, and safe operation. It also involves determining the air parameters after treatment in the air handling room and the air parameters of the regulated rooms, summarizing the corresponding relationships between various parameters. The adjustment effect of the automatic control system is tested, allowing self-control components, devices, instruments, and equipment to withstand long-term tests to meet the requirements for safe and reliable system operation. Finally, it establishes the allowable fluctuation range of air parameters that meet the requirements within the regulated room.
(2) Items and contents of measurement: Temperature and humidity before and after each air treatment device in the air handling room, including fresh air temperature and humidity, return air temperature and humidity, temperature and humidity before and after the primary heater, Beijing York Air Conditioning After-sales Service Phone; air temperature and humidity in the mixing chamber, outlet air temperature and humidity from the spray chamber, temperature and humidity before and after the secondary heater, etc. Dust content before and after each major process in the air handling room, including fresh air dust content, return air dust content, mixed state dust content, and outlet air dust content from the spray chamber, etc. Wind speed and wind pressure at the main cross-sections of the air handling room and ductwork, equipment resistance (including wind pressure and wind speed of the spray chamber and ductwork), equipment resistance of the primary heater, secondary heater, spray chamber, coil cooler, and filter, etc. Air temperature in the regulated room. Sensitivity of actions by sensitive elements, regulators, executive elements, conversion elements, and adjustment mechanisms in the automatic control system.
(3) Precautions for arranging measurement points: Arrange measurement points according to the status points mentioned in item 2. Measurement should consider consistency in reading time, and readings must be accurate. For temperature, humidity, and wind speed measurements, consider taking average values or points close to the average value. For dust content measurement, ensure air flow stability.
