_ The principle greenhouse accessories greenhouse accessories manufacturer of artificial greenhouse warming is artificially generated heat, and let it heat a medium, and then use some means whereby the media and distribute heat evenly to all parts of the greenhouse. Therefore heating system should include four parts heat, heat transfer medium, heat transfer systems, pressure devices. (1) source: source is a heat generating means which chemical or electrical energy into heat energy. There are commonly used in the greenhouse heat boilers and heaters. Divided according to the fuel used, the boiler there are two kinds of oil and coal burning. Oil boiler pollution, but higher operating costs. Boiler both energy conversion and transfer two functions. The boiler will tender compound of chemical energy into thermal energy, and then heating it surrounding medium - water, i.e. the heat transferred to the water. According to state media heat after the pot is divided into pressure and high-pressure retaining two. Pressure boilers to supply hot water systems, and high-pressure furnace key to the system supplying water vapor. Steam heating is not required pressure device (such as pumps), but with steam through pipes heating, greenhouse heating up fast. Cooling too fast, large indoor temperature changes, plus pay special attention to security issues between the high-pressure boiler at runtime, so the greenhouse Multi-use pressure boilers.
