Abstract

Introduction. Electric boilers are considered as an important element of the energy transition from the use of hydrocarbon fuels to renewable energy. Electric boiler is one of the popular solutions of “Power-to-Heat” technology, widely used in households for heating with water systems with radiators and low-temperature heating devices of the “floor heating” type. The paper considers a variant of Joule heating of the coolant of heating systems, by means of which heat is released when an electric current passes through a conductive element. Materials and methods. The object of the research is the variants of designs of heat exchangers for generating heat energy using resistor heating elements of normal conductor and semiconductor type. Various variants of indirect heating of the coolant and contacts of the surface of the heating elements with the coolant are considered. Methods of comparative analysis and scoring of the applicability of various designs are used in the work. Results. The classification of electric boilers by types of heating resistors, by contact, by placement of heating elements in the heat exchanger, by the shape of the heat exchanger, by the variant heating element contact with the coolant is presented. A comparative comprehensive analysis of variants of electric heat generators is given. Conclusions. The results of comparative analysis of design variants of electric boilers show the prospectively of using semiconductor thermistors as heating elements. According to the design of the heat energy generation chamber in terms of compactness, power density and reduction of precipitation conditions for coolant stiffness, channel plate electric heat exchangers are the most effective.

自主热水系统电热锅炉的分类
介绍。电锅炉被认为是能源转型的重要组成部分,从使用碳氢化合物燃料到可再生能源。电锅炉是“电转热”技术的一种流行解决方案,广泛用于家庭使用带有散热器的水系统和“地板采暖”型的低温采暖装置。本文考虑了加热系统冷却剂焦耳加热的一种变体,当电流通过导电元件时,通过焦耳加热释放热量。材料和方法。研究的对象是利用普通导体和半导体型电阻加热元件产生热能的热交换器的各种设计。考虑了冷却剂的各种间接加热和加热元件表面与冷却剂的接触。在工作中采用了对各种设计的适用性进行比较分析和评分的方法。结果。按加热电阻的类型、接触方式、加热元件在热交换器中的位置、热交换器的形状、加热元件与冷却剂接触的不同方式对电锅炉进行了分类。对不同型号的电热发生器进行了比较综合分析。结论。通过对电锅炉设计变量的对比分析,显示了采用半导体热敏电阻作为加热元件的前景。根据热能产生室的设计,在紧凑性、功率密度和减少冷却剂刚度沉淀条件方面,槽板式电换热器是最有效的。
