If you are not looking for this company but want to learn about technical knowledge or products related to electric heating, I can also provide you with relevant information. For example: Working principle: An electric heater is a device that converts electrical energy into thermal energy using the thermal effect of current (Joule's law).
In the industrial electric heating field, the most core "first" standard usually refers to the "Safety of electric heating equipment - Part 1: General requirements" (corresponding to the national standard GB 5959.1 series, equivalent to the International Electrotechnical Commission IEC 60519-1 standard). Core content: This is the basic safety criteria for electric heating and electromagnetic treatment devices.
Electrical work (W): total work done by electric current, i.e., total electrical energy consumed. Formula: W = UIt (voltage × current × time). Electric heat (Q): heat generated by current passing through a conductor (Joule heat). Formula: Q = I²Rt (square of current × resistance × time), which is Joule's law. Electric power (P): work done by current per unit time. Formula: P = UI.
In the training and assessment system of the power system (especially for electric heating and electrical testing trades), theoretical knowledge and operational skills are usually divided into different modules or levels. The following are speculations and analyses based on common classifications in the power industry.
This is a small and micro enterprise located in Lanzhou City, Gansu Province, whose predecessor was a collectively owned enterprise. Full name: Lanzhou Electric Heating Appliance Factory No. 2. Establishment date: June 30, 1984.
This is the most popular 'four-dimensional' concept in the current energy internet and new power systems. Building on the 'electricity-heat-gas' you previously learned, it adds 'cooling' (refrigeration/cold energy). Core logic: Break down the barriers among the four energy categories of electricity, heat, cooling, and gas. Through equipment such as heat pumps, absorption chillers, and gas turbines, achieve coordinated conversion and cascade utilization of the four energy types.
