Strictly speaking, the radiator heat dissipation is not calculated, but is detected by a specialized agency. It is generally based on the provisions of the national standard GB/T13754-1992, by China Radiator Quality Supervision and Inspection Center and Tsinghua University Physical Environmental Testing Center thermal performance testing. The heat dissipation of radiators of different models and different materials is different. In most cases, manufacturers will provide heat sinks for various types of heat sinks.
The amount of radiator heat that the user needs to calculate refers to the actual heat demand of the room, which is the basis for the number of radiators to be purchased. In a house, the area of ​​a bedroom, dining room, kitchen, bathroom, etc. is known and can be used as the basic data for testing heat dissipation. We can measure the total heat dissipation of the rooms in accordance with the heating index of residential buildings, residential 45-70, offices, schools 40-80, hospitals, kindergartens 65-80, single-story residential 80-105, canteens, restaurants 115-140 (unit: W / Square meter). According to the use of the house, consumers can use the above data to multiply the above data to obtain the heat supply needed by the room.
However, the numerical values ​​obtained by the above method are theoretical values, and some factors need to be considered in the actual use process, such as room orientation, warmth, etc., and 10-20% of the amount of wealth may be appropriately added to prevent insufficient heat during winter use. Happening.
Calculate the amount of heat required for the room, and the user can calculate the number of pieces of heating that need to be purchased based on the heat dissipation of each radiator, and then calculate the number of sets that need to buy heating. However, for the convenience of users, some companies will pre-mark the area of ​​each radiator, such as the St. Lawrence WF (Y) 50-600 cooling area of ​​1.0 square meters / piece, so that users simply use the room area divided by this The parameters give the number of radiators, making the entire purchase process time and labor saving.
Hearing Protection refers to devices used to protect the ear, either externally from elements such as cold, intrusion by water and other environmental conditions, debris, or specifically from noise. High levels of exposure to noise may result in noise-induced hearing loss. Measures to protect the ear are referred to as hearing protection, and devices for that purpose are called hearing protection devices. In the context of work, adequate hearing protection is that which reduces noise exposure to below 85DB over the course of an average work shift of eight hours.Different types of hearing protection may be utilized to maximize hearing protection. OSHA regulations dictate whether hearing protection is required and if the company must participate in a hearing conservation program.
