Underground Heat Exchange Station Water Leakage Alarm System Design

Hohhot is the capital of the Inner Mongolia Autonomous Region and a typical northern city.Heating is a hot topic every winter.Urban heating mainly depend on the regional boiler room and central heating.Hohhot ChengFa Heating Limited Liability Company is mainly responsible for the new city.Four heating branch,the proportion of heating area more than 20%of the urban area.Three heat source plants use coal burning heating,and other heat source plant uses waste heat of power plant.XingJiaYing Factory in ChengFa Heating Limited Liability Company has 8 boilers,heating area of 8 million square meters,and 80 heat exchange stations,including 25 under-ground heat exchange stations,which mainly distributed in residential garage and office buildings.Underground heat exchange stations has a lot of problems in the process of construction and installation,especially security issues are worthy of attention.The design of leakage alarm system,is on the premise of the unattended,ensuring the underground heat station from leakage and avoiding significant losses,to ensure effective heating on time.With the development of the construction of urbanization in our country,central heating has become the main direction of development in all cities,because it's economic and environmental.It attracts more and more attention by the government owe to it's energy-efficient,environmental and low-carbon.Central heating must be carried out in city networks,however,the performance of the unattended intelligent heat exchange station is key to achieve safety,steady,environmental,cost-saving,It will be more difficult when it refers to underground heat exchange station.This paper conducts a simulation test of the leakage alarm system of the underground heat exchange station and gets some satisfactory results.
