A condenser and an evaporator are two important components in a refrigeration system.

A condenser and an evaporator are two important components in a refrigeration system. A condenser is responsible for releasing heat from the refrigerant gas to the surrounding air, causing the gas to condense into a liquid. This process increases the pressure of the refrigerant and prepares it to be sent to the evaporator. On the other hand, an evaporator is responsible for absorbing heat from the surrounding air or a substance (such as food in a refrigerator) and allowing the refrigerant to evaporate into a gas. This process cools the surrounding area or substance. In summary, a condenser releases heat and turns the refrigerant gas into a liquid, while an evaporator absorbs heat and turns the liquid refrigerant into a gas. Both components play a crucial role in the refrigeration cycle to maintain a cool temperature.

1, cold tons (RT) Air conditioning and refrigeration units, cold tons, also known as refrigerated tons, refrigerated tons refers to the energy required to freeze a ton of water into ice. (Note: 1 cold ton is to make 1 ton of 0 degrees Celsius water in 24 hours to 0 degrees Celsius ice required by the amount of refrigeration.) 1 ton of 0 degrees Celsius water, the ability to convert into 0 degrees Celsius ice within 24 hours, the freezing ton indicates the refrigeration capacity of the freezer. 2, power (W) Power is the work done by an object in a unit of time, that is, power is a physical quantity that describes the speed of doing work. The amount of work is certain, the shorter the time, the greater the value of power. The formula for finding power is power = work/time. Use power to describe the speed of work, the amount of work done per unit time is called power. 3.Pressure-enthalpy diagram The pressure-enthalpy diagram is a map of the refrigerant, which indicates the thermodynamic properties of the refrigerant (pressure, temperature and pressure). Temperature. Heat, etc.), pressure-enthalpy diagram draws a refrigeration cycle refrigerant state changes, according to the diagram can be calculated. According to this diagram, the cooling capacity can be calculated, the heat of condensation, and the operation status of the refrigeration equipment can be determined. 4.Enthalpy-Humidity diagram Enthalpy and humidity diagram indicates the relationship between the air parameters of the line diagram. Enthalpy and humidity diagram is like a dictionary, you can look up the word (other parameters of air) according to the pinyin (a parameter). 5.Refrigerant thermal property table The table of thermal properties of refrigerant lists the temperature (saturation temperature) and pressure (saturation pressure) and other parameters of the refrigerant in the saturated state. Refrigerant temperature and pressure in the saturated state is - a corresponding. What is saturation? Refrigerant gas and liquid coexistence state. Gas-liquid equilibrium, the gas is called saturated vapor; liquid is called saturated liquid; pressure is called saturated vapor pressure; temperature is called saturation temperature. The refrigerant in the evaporator, condenser, gas-liquid separator, and low-pressure recirculation drum is generally considered to be in a saturated state. In the saturated state of the vapor (liquid) is called saturated vapor (liquid), the corresponding temperature and pressure is called saturation temperature and saturation pressure. 6, condensing temperature The condensing temperature of the compressor system, is the temperature of the refrigerant in the condenser condensation, the temperature corresponding to the refrigerant vapor pressure that is the condensing pressure. Condensing temperature is one of the main operating parameters of the refrigeration cycle, for the actual refrigeration device, due to other design parameters change range is small, the condensing temperature can be said to be the most important operating parameters, which is directly related to the refrigeration effect of refrigeration devices, safety and reliability and energy consumption level. 7.Evaporating temperature Evaporation temperature refers to the temperature of the refrigerant in the evaporator evaporation boiling, which corresponds to the corresponding evaporation pressure, evaporation temperature is also an important parameter in the refrigeration system. It reduces every 1 degree, the same amount of cold need to increase the power of 4%, so in the conditions permit, appropriate to improve the evaporation temperature, to improve the efficiency of the refrigeration system is favorable, but not the lower the better. Evaporation temperature in the ideal state that is the refrigeration temperature, but the actual operation of the refrigerant evaporation temperature than the refrigeration temperature is slightly lower than 3 to 5 degrees. 8, suction temperature Suction temperature refers to the refrigerant into the compressor temperature, it is generally higher than the evaporation temperature. Because the evaporating temperature is the saturation temperature of the refrigerant, while the suction temperature is the temperature of the superheated gas, when the refrigerant becomes superheated gas. The difference between the suction temperature and evaporation temperature is the suction superheat. 9.Superheat Superheat is defined as the temperature difference between the low-pressure side and the vapor in the temperature-sensitive package. Measurement of superheat in the location as close as possible to the sensing package to measure the evaporating pressure, and will be converted to temperature readings, and then use the sensing package of the actual temperature measured at the temperature minus the temperature. The degree of superheat should be between 5 and 8°C. 10.Subcooling degree Definition of subcooling: the difference between the saturated liquid temperature corresponding to the condenser condensing pressure and the actual temperature of the condenser outlet liquid. Engineering, the exhaust pressure is generally approximated as the condensing pressure, the exhaust pressure corresponding to the saturated liquid temperature and the condenser outlet liquid temperature difference, as the degree of subcooling. The reason for this approximation is that the pressure drop of the condenser is relatively small compared to the evaporator. For air-cooled condenser, 3 to 5 degrees of subcooling is more appropriate. Refrigeration system normal cycle, the condenser outlet will generally have a certain degree of subcooling. 11, suction superheat Suction if there is no superheat, there may be back to the gas with liquid, or even cause wet stroke liquid damage to the compressor. In order to avoid this phenomenon, a certain degree of suction superheat is needed to ensure that only dry steam into the compressor. Too high a degree of superheat also has the disadvantage of high superheat will cause the compressor exhaust temperature (exhaust superheat) increases, the compressor operating conditions deteriorate life reduced. Therefore, the suction superheat should be controlled within a certain range.

How should I protect my air conditioning unit from freezing in the winter?

Winter is not only our own need to prevent cold and warm, as refrigeration people, we also have to "care and maintenance" of our refrigeration equipment, especially in the cold north, pay attention to the central air conditioning also need to do a good job of cold measures, especially shopping malls, manufacturing enterprises, hotels and other large-scale field of commercial central air conditioning need to prevent freezing, then how to prevent freezing, freezing there! What measures? First, the host of the anti-freeze The host condenser or evaporator import and export valves closed, the water discharge valve and air release valve open, and then use compressed air to blow the remaining water. Second, the water pump anti-freeze Close the refrigerant pump inlet and outlet valves, and open the pump drain valve and air release valve to drain the water. The lowest point of the cooling water system valve open, put the cooling water, and open the water pump drain valve, to be the system after the water put clean, in order to prevent rainwater through the cooling tower into the cooling tower, close the cooling tower out of the water valve, open the cooling tower catchment disk drain valve, so that the rainwater in a timely manner from the drain valve drain off. Third, the cooling tower water pipe anti-freezing General cooling tower water supply pipe exposed to the outdoors, most of the designers are using insulation method of anti-freeze, but the actual use of the process, even if the insulation is often frozen phenomenon. In order to solve this problem, in the cooling tower water supply pipe from the indoor connection, additional valves, in the water supply pipe at the lowest point to increase a water discharge valve. When winter comes, the valve will be closed indoors, and will be the lowest point of the discharge valve open, the outdoor pipe water discharge, so that the pipe does not need insulation and will not be frozen. Fourth, the expansion tank of anti-freezing Expansion tanks are generally located in the roof or the top floor of the equipment room, expansion tanks, although the appearance of insulation, and has a circulating pipe, but the actual use of the circulating pipe can really play a circulating role in very few, that is, in the winter there is an expansion tank of water in the long term in a low-temperature environment, although the insulation will still be frozen, the expansion tank is frozen can not play the role of expansion, the temperature within the system rises, then the pressure increases. In order to solve this problem, in the construction of air conditioning water supply pipe can be set up a DN20 interface, install a valve to open properly to ensure that the water in the tank to get the cycle of water. (This article comes from the refrigeration encyclopedia weibo public number) If the night does not use air conditioning, water pumps stop before the valve can be opened all the way, so that the expansion tank of water temperature, can ensure that the pump stops for a long time after the expansion of the water tank does not freeze. Fifth, the new air system to prevent freezing The role of the fresh air unit is to send the outdoor fresh air into the rooms after treatment, in winter, the fresh air unit heats the outdoor cold air, that is, the fresh air unit table cooler directly in contact with the outside world cold air, in order to prevent the table cooler is frozen when the heating is stopped, the fresh air inlet should be added to the motorized multi-leaf regulating valves, and the fresh air unit linkage. When the new air unit is running, the air valve is open, and when the new air unit is closed, the air valve is closed, so as to prevent the new air unit and the refrigerant water pump from stopping the operation, the cold outdoor air will directly cool the water in the water-cooled table cooler, so that the water freezes and freezes, freezing the table cooler. Sixth, add antifreeze In winter, the unit is not convenient to drain the water to empty and the possibility of water and electricity cuts, equipment heating must be added to make up the antifreeze, and must be based on the lowest local temperature as an important parameter in the choice of antifreeze. The main component of antifreeze is ethylene glycol, antifreeze from the water tank into the water system after the discharge of frozen water, first injected antifreeze liquid, not enough and then injected into the frozen water, and then turn on the pump so that the antifreeze and the water is fully integrated, by the way, the water system of all the air out of the water system, the water system can not be air, the presence of air will make air-conditioning equipment to report the flow of water to switch the protection, but also prone to the formation of vapor corrosion. Seventh, all the frozen pipe insulation The main purpose of frozen water pipe insulation is to prevent condensation on the outside of the pipe, there is also a role in preventing the water inside the pipe from freezing, the thickness of the insulation layer is generally more than 20mm. In addition, but also in the water pipe outside around the electric accompanied by tropical, as long as to accompany the tropical power supply, it can continue to give the pipeline heating, is the water temperature in the pipeline in more than 10 ℃, plus accompanied by the tropical outside of the heat preservation, there will not be because of icing caused by the hot water machine lack of water protection. The accompanying heat tape should choose with limit thermostat, keep a certain temperature on it. Eight, case study Case 1: There is a villa user, the family does not often live in people, last winter to go abroad for vacation, the electricity all cut off, and no drainage, as a result of the return of the machine after all frozen. Winter temperature in the north is low, because of the long time not used without drainage, resulting in the machine all frozen. Case 2: In a rural area, the machine froze in winter and called the contractor to repair it. The temperature is very low in winter, if the anti-freezing is not done well, it is easy to be frozen. Water will freeze when the temperature is lower than 0℃, the volume of water expands when it freezes, and the expansion coefficient of pipe and water is different, so when the water temperature in the pipe is lower than 0℃, the pipe has the possibility of freezing, when the ambient temperature is lower than 0℃, and the unit is not powered on or the unit is in standby state when the internal antifreeze protection is out of order.
