6、on and air conditioning, etc., so as to make them comply with the national current standards.2.According to the gist of n Several Provisions for Plant Design of China Petrochemical Group Corporationclauses in terms of the reductions in personnel, land coverage and investment, saving energy, etc.，hav

7、e been revised and added.3.Taking into account the wide applications of the Distributed Control System (DCS) in the petrochemical projects, the experience in the design of the air conditioning for the DCS control room has been summed up, and the clauses in terms of the environmental conditions for D

8、CS control room, the control and operation of air conditioning system, the air current composition, etc., have been added and revised.4.A part of the clauses regarding safety aspects have been added and revised, such as the centralized monitoring and control of the major ventilation and air conditio

9、ning units and stand by of the equipment, the interlocks of the air conditioning units of DCS control room with the fire automatic alarm system, the exhaust of the rooms equipped with the full gas submerging fire fighting system, etc.5.Those clauses in the original code which are seldom used or diff

10、icult to function, are cancelled or modified, such as heating with steam-ejection hot water, the recycle of condensate for the steam heating system, diffusive explosion hazardous substances or harmful gases and vapor, and distribution of overall exhaust rate for the plant buildings, etc.During revis

11、ion, wide surveys and studies have been made based on the problems existing in the original code, the practical experiences of the recent years in the design of heating, ventilation and air conditioning in the petrochemical industry have been summed up, the comments on the relevant design, construct

12、ion, operations, etc., have been asked for, the major problems found have been discussed several times and the code is flnalized after review is made.In case any modiHeation and supplementation is found necessary during the implementation of this Code, please provide the comments and relevant inform

17、es of Wording 57Attachment: Explanatory Notes1.General Principles1.0.1 This Code is established for the purpose of implementing the relevant national general and specific policies in the design of heating, ventilation and air conditioning (HVAC) for the petrochemical enterprises, so as to provide ne

18、cessary conditions for safe production activities, improvement of labor conditions, product quality assurance, environmental protection and rational utilization of resources.1.0.2 This Code is applicable to the design of HVAC of the newly constructed, expanded and rebuilt production plant buildings

19、and annex buildings for the petrochemical enterprises.1.0.3 The operation status and major parameters shall be centrally monitored and controlled for those HVAC units which exerts relative significant effect on the production safety and product quality.1.0.4 In the design, the full-tine or part-time

20、 specialized technical personnel and the operation and maintenance personnel, as well as the appropriate testing instruments shall be specified according to the quantity, importance and complexity level of the HVAC units.1.0.5 During the implementation of this Code, the requirements set in the natio

21、nal current mandatory standard H Design Code for Heating, Ventilation and Air Conditioning in Petrochemical Industryn and the other relevant current standards and specifications shall be satisHed.2.Heating2.1General Provisions2.1.1Centralized heating system shall be provided for the plant buildings

22、and the annex buildings in the regions where the number of days with a mean daily temperature for years constantly 5C is greater than 90 days, and there are some people usually staying in rooms or certain requirements for room temperatures made for the production.2.1.2Centralized heating system is a

23、llowed to provide for the plant buildings and annex buildings in the regions where the number of days with a mean daily temperature for years constantly 5C is 45 59 days, and the mean RH value for the coldest months for years is equal to or greater than 75% and there are operation personnel staying

24、collectively and frequently, provided that there is waste heat in the plant area that can be utilized and it is approved by the department in charge.2.1.3Centralized heating system is allowed to provide for plant buildings and annex buildings in the regions other than that as specified in Clause2.1.
