Description

technical field [0001] The invention relates to a hydraulic balance debugging device and a debugging method for a HVAC system. Background technique [0002] The structure of the HVAC system generally includes a primary pipe network that is connected to the thermal station and forms a circulation loop, a heat exchanger, and a secondary pipe network that forms a circulation loop. The primary pipe network and the secondary pipe network pass through the heat exchanger connected. There are several user ends on the secondary pipe network, and each user end has a regulating valve. In order to meet the heat supply needs of more users, a tertiary pipe network that can form a circulation loop can also be connected in parallel on the primary pipe network and / or the secondary pipe network. There are several user terminals connected in parallel on the tertiary pipe network, and each user end Both have regulating valves and the access end of the tertiary pipe network has control valves....

AI Technical Summary

Problems solved by technology

However, the basis and necessary condition of the on-off time area method is the hydraulic balance of the heating system. Due to the unbalanced flow among households, the gap between the heat consumption effect and the heat charge between users will be 20%-30%, which will cause Poor heating quality, uneven heating and cooling, unreasonable heat metering and difficulty in charging

[0004] At present, the hydraulic balance debugging methods for HVAC systems include proportional method, compensation method, etc. Although all of them can carry out hydraulic balance debugging, the debugging process is complicated and time-consuming.
