Do you know other refrigeration air-conditioner method

< p > other air-conditioner refrigeration methods do you know it in the commercial freezer refrigeration system, there are many kinds of cooling methods, this basically is divided according to the air-conditioner in the future use. This series of refrigeration and commercial freezer refrigeration way? Certainly is not the same. Way of air-conditioner refrigeration is refers to the external air or cold, and refrigeration system, refers to the internal cooling method of air-conditioner. Below and take a look at the cooler price this knowledge and experience, the first is the throttling refrigeration air-conditioner system: a certain pressure of fluid in pipe flow process, if the cross-sectional area of a portion of the pipe all of a sudden narrowing, flow experience due to the effect of local step-down, this phenomenon is called the throttle, fluid temperature after the throttle is reduced. Therefore, throttling after low temperature gas can be used as a source of refrigeration, cooling and throttling may also make a liquefied gas. Followed by the expansion refrigeration air-conditioner system: high pressure gas insulated expansion on the one hand, can lower the temperature, the cooling effect; On the other hand also an isothermal expansion process, recycled energy, improve the efficiency of the refrigeration unit. Gas in throttling and expansion process are cooling refrigeration effect, but the gas adiabatic throttling refrigeration temperature must be lower than at the beginning of transition temperature, the gas temperature is always lower after the adiabatic expansion. So in actual application according to the need to choose proper cooling mode. In high temperature and high pressure or high temperature and medium pressure, for instance, often chooses adiabatic expansion refrigeration: the temperature is lower, the throttling refrigeration effect is good: as for liquefied gas, tend to combine the two methods, the composition of gas liquefaction system, and air-conditioner external cooling manner is not the same. < br / > < / p >
