Introduction
The central electric heating system is a new application of traditional electrothermal conversion technology and electric heating appliances:
new fusion of technologies: Features or advantages of central heating systems compared to traditional electric heating appliances include:
a) Integrate multiple traditional electric heating appliances that exist in isolation and operate independently into one system, so that they and their connections with other electric heating appliances in the system
Other components are related to each other, interdependent, and coordinate operation;
b) In order to realize the energy saving of traditional (resistive) electric heating appliances and the energy saving effect of other types of electric heating appliances
Ascension provides conditions;
c) Lay the foundation for improving the comfort and convenience of household electric heating;
d) It provides the possibility to realize the correlation between the electric heating process and effect, indoor and outdoor environmental conditions and indoor personnel physical conditions;
e) For the construction of smart homes, solutions in the field of electric heating are supplemented:
The focus of the standardization of the central electric heating system built on the basis of new application forms of existing technologies and products is to solve problems arising from systematization:
unique problem: That is, the new risks that may arise due to "systematization" and the new functions that can be realized (corresponding to known or unknown new requirements);
"Systematization" brings consumers a better user experience or better product evaluation results:
The pursuit of the above-mentioned unique problems and their solutions is exactly the necessity of developing the central electric heating system, and it is also the standard of the central electric heating system:
The necessity of standardization:
In order to standardize the technical requirements of central electric heating systems for household and similar purposes, and provide consumers with high-quality products and user experience, the
GB/T 42389 "Central Electric Heating Systems for Household and Similar Purposes": GB/T 42389 is proposed to consist of five parts:
--- Part 1: General requirements: The purpose is to establish the general principles and relative
related rules:
--- Part 2: Technical specifications for system design, installation and project acceptance: Intended for use in central electric heating systems for domestic and similar purposes
Design, installation and engineering acceptance establish operable and verifiable procedures and related rules:
--- Part 3: System energy efficiency evaluation: The purpose is to establish an operable,
Verifiable procedures and ratings are given:
--- Part 4: Evaluation of system economic operation: The purpose is to determine the economic operation evaluation of domestic and similar central electric heating systems:
Actionable and verifiable procedures:
--- Part 5: Specifications for after-sales service: The purpose is to establish operational,
Verifiable procedures and associated rules:
Central electric heating systems for domestic and similar purposes
Part 1: General requirements
1 Scope
This document specifies the classification, system architecture, technical requirements, explanatory materials, installation and after-sales service of central electric heating systems for household and similar purposes:
services and evaluation methods:
This document applies to single-phase appliances with a rated voltage not exceeding 250V and other appliances with a rated voltage not exceeding 480V, used in households and similar places
Design, integration, identification and evaluation of the central heating system used:
Central heating systems to which this document applies include but are not limited to:
---Central heating systems used in various rooms in the family such as bedrooms, living rooms, bathrooms, study rooms, kitchens, etc:;
---Central heating systems used in classrooms, office buildings, canteens, activity rooms, and libraries of various schools such as universities, middle schools, and elementary schools;
---Central electric heating used in kindergartens, activity places for the elderly, nurseries, hospitals, special education schools and other places where special people gather
system;
---Central electric heating systems used in offices, workshops, construction sites and stadiums, etc:
Note: The above central heating system used in some places may require additional requirements:
