Water heater: Water heater is a kind of heating equipment mainly for heating. It is mainly used in the northern areas where winter is cold, and has the function of keeping warm. Cast iron radiators were mostly used in the past, but now more materials have been developed. Cast iron radiators have gradually withdrawn from the market stage, and new radiators such as steel radiators, copper-aluminum composite radiators and aluminum radiators are superior to cast iron radiators in materials and manufacturing processes, becoming the most mainstream radiators in the market.
Floor heating: Floor heating is the abbreviation of Radiant floor heating, which is radiant in English.
floor
Heating, which uses the whole ground as radiator, heats the whole ground evenly by radiating the heat medium in the floor, and uses the law that the ground itself stores heat and radiates upwards to conduct from bottom to top to achieve the purpose of heating. Water heating system refers to a heating method that heats water to a certain temperature, transports it to the water pipe cooling network under the floor, and realizes the heating purpose through floor heating. The low-temperature geothermal medium forms a gradually decreasing temperature gradient from the sole of the foot to the head indoors, which gives people the comfort of warming their feet and cooling their heads. Radiant floor heating conforms to the fitness theory of "warm feet and cool roof" in traditional Chinese medicine. It is the most comfortable heating method at present and a symbol of modern life quality. As far as heat medium is concerned, it can be divided into two categories: liquid circulation system and electric floor heating, and as far as pavement structure is concerned, it can be divided into wet floor heating and dry floor heating. Dry floor heating does not need to backfill peas (ultra-thin). From the surface decoration materials, it can be divided into floor floor heating and floor tile floor heating; Functionally divided into ordinary floor heating and far infrared floor heating.
Air conditioning: The low-pressure gas inhaled by the compressor is compressed into high-temperature and high-pressure gas by the compressor, and the high-temperature gas raises the water temperature through the heat exchanger, and at the same time, the high-temperature gas will condense into liquid. The liquid evaporates when it enters the evaporator. (When the evaporator evaporates, there must also be a heat transfer medium. According to the different heat transfer media, the model and structure of the machine are also different. Commonly used are air cooling and ground source. After the liquid passes through the evaporator, it becomes low-pressure and low-temperature gas, and the low-temperature gas is sucked by the compressor again for compression. In this way, the circulating water on the air conditioning side will become hot water of about 45-55 degrees. The hot water is sent to the room that needs heating through the pipeline, and the room is equipped with a fan coil unit, so that the hot water can exchange heat with the air to achieve the purpose of heating.
Heating furnace: heating furnace refers to a hot water boiler which is completely controlled by manual operation or microcomputer and uses hot water circulation pump to circulate hot water in the boiler and heating pipeline to meet the heating requirements. This equipment is widely used in government agencies, enterprises, factories, hospitals, schools and hotels.
, hotels and other enterprises and institutions to use.
