The IP rating of
Led Vapor Tight Fixtures is 66. It is dustproof, waterproof,
anti-corrosion, and anti-UV. It can effectively prevent the lamp body from
being easily oxidized and broken after exposure. The integrated design makes
installation more convenient and quicker. It does not need to be installed and
connected in series after the lamp body is open like the traditional
three-proof light. So it can effectively shorten the construction period and
reduce labor costs.
There is a respirator at one end of the
lamp body, which can avoid thermal expansion and contraction when the lamp body
is working, and water droplets appear on the wall of the lamp body, which
affects the service life of the lamp beads.
Our LED Tri-proof
Light are connected in series without the use of tools. Cylindrical
design, which make cleaning more easily.
Refrigeration compressor condensing temperature and condensing pressure
Author: Beijing Hengxing and Technology Co., Ltd. Source: http: //
The temperature at which the refrigerant gas condenses into a liquid under a certain pressure in the condenser is referred to as a condensing temperature, and the pressure corresponding thereto is referred to as a condensing pressure. The condensing temperature of the refrigeration system during operation depends on the temperature of the cooling medium, and is related to the form of the condenser and the temperature of the effluent of the cooling water. For water-cooled vertical, horizontal shell and tube and shower condensers, the condensation temperature is 4 to 6 °C higher than the cooling water outlet temperature. The condensing temperature of the evaporative condenser is related to the humidity of the air, which is about 5 to 10% higher than the wet bulb temperature of the outdoor air. For air-cooled condensers, the condensation temperature is 8 to 12% higher than the air temperature.
The discharge pressure of the refrigerant compressor can be approximated as the condensing pressure, and the condensing temperature can be calculated using the exhaust pressure. For example, for an air conditioning R22 chiller, the readings on the suction and exhaust pressure gauges are 0.431 MPa and 1.289 MPa, respectively. Then, the venting pressure of the chiller (ie, the condensing pressure) is converted into an absolute pressure of l. 389MPa, check R22 saturated steam thermal performance table, the corresponding condensation temperature is 36 ° C, then the cooling water outlet temperature should be 31 ° C; the suction pressure (ie evaporation pressure) converted to absolute pressure is 0.531MPa, check R22 saturated vapor Thermal performance table, the corresponding evaporation temperature is 2 °C. The heat exchange temperature difference of the indirect cooling system is 5 ° C, then the outlet water temperature of the refrigerant water is 7 ° C.
