Xuzhou Sheng Erda Refrigeration Electrical Services Limited five, air conditioning, refrigeration, heating principle: endothermic evaporation, condensation heat. When freon gas is pressurized refrigerant compressor, into the high pressure condenser, is condensed into a liquid heat, reduced pressure in liquid Freon enters the throttling device in the low pressure evaporator, the evaporation of the gas, and absorbs heat from the indoor, so as to achieve cooling purposes. Heating and cooling runs contrary, when the compressor produces the reverse cycle heating refrigeration cycle. Is also considered cooling operation, the air conditioner from the heat absorbed by the outdoor to the indoor wind. Heating principle is that the air conditioner refrigerant in the atmosphere absorb calories (ie solar) as a heat source to warm the room. This is an excellent performance, efficient manner. It is only used to drive electric motors, electric furnace is to make a direct energy, air conditioners only about one-third of its electricity, and therefore economical, safe and clean. Even at low outdoor temperatures, the air conditioners can also take the heat from the atmosphere. The secret is the superior characteristics of the refrigerant, the heating operation when outdoor air-conditioning unit within the freon is about -40 ℃, the temperature is very low, is assumed when the outdoor temperature is 5 ℃, the temperature difference between the two is still great, the refrigerant can absorb the portion of the thermal energy, which is supplied to the indoor. Xuzhou 圣尔达 Refrigeration Electrical Services Limited ☆ photocatalyst such filters can adsorb at room temperature, harmful substances, then the way to oxidative decomposition of harmful substances adsorption. Photocatalyst will produce saturation, but then after some time, simply put it under ultraviolet light or sunlight for regeneration, it also can restore its role in the. ☆ cold catalyst filter class at room temperature can be directly and completely decompose formaldehyde and other harmful substances and the smell of gas, and has antibacterial function Xuzhou central air conditioning prices, the effect is outstanding. It requires no regeneration, replacement, cold catalyst is more advanced than the photocatalyst. ☆ electrostatic dust filter capable of such air flows through electrostatic adsorption, get rid of dust in the air, clean air, valid for very long. ☆ electronic smoke and dust inside the machine machine settings ion integrated circuits, by electrostatic interaction indoor smoke and odor Xuzhou transformation telephone central air conditioning, clean absorption, and directly down into harmless substances, but also the indoor air fresh. Xuzhou transformation of central air conditioning central air conditioning _ _ Telephone Sheng Erda provided by Xuzhou 圣尔达 Refrigeration Refrigeration Electrical Services Limited. Xuzhou 圣尔达 Refrigeration Electrical Services Limited (xzktw.com) strong, credible, in Xuzhou heat exchangers, refrigeration and air conditioning equipment industry has accumulated a large number of loyal customers.
