The high-temperature low-pressure refrigerant is compressed in the compressor to form a high-temperature high-pressure gaseous refrigerant, the high-temperature high-pressure gaseous refrigerant further releases heat in the condenser, the temperature of the refrigerant is reduced, the refrigerant is changed into a liquid state or a gas-liquid mixed state (low-temperature high-pressure liquid refrigerant), the refrigerant flows through the throttling device, is reduced in pressure and flows to the evaporator, the refrigerant exchanges heat with indoor air in the evaporator, the temperature of the refrigerant is increased to form the high-temperature gaseous (low-pressure) refrigerant, and the refrigerant flows into the compressor to complete refrigerant circulation.
An embodiment of the utility model provides an air conditioning system, refer to fig. 1, include: an evaporator (not shown) for exchanging heat with indoor air; a compressor (not shown) for compressing a gaseous refrigerant; evaporative condenser 100, evaporative condenser 100 include casing 11, and casing 11 top is equipped with air exit 18, is equipped with from top to bottom along vertical direction in casing 11 in proper order: the water-saving device comprises a first fan 19, a water baffle 12, a spraying device 13, a heat exchange coil 14 and a water receiving disc 15, wherein the first fan 19 is arranged at an air outlet 18, and the water receiving disc 15 is connected with the spraying device 13 through a first circulating water pump 16 and a first water supply pipeline 17; an air-cooled condenser 200; the refrigerant pipeline 300, the evaporator, the compressor, the heat exchange coil 14 and the air-cooled condenser 200 are sequentially communicated end to end through the refrigerant pipeline 300 to form a refrigerant loop.
The embodiment of the utility model provides an air conditioning system, evaporative condenser 100 and air-cooled condenser 200 establish ties through refrigerant pipeline 300 and set up, and the direction evaporative condenser 100 that flows along the refrigerant is located the front side (the upper reaches) of air-cooled condenser 200. When the condensing pressure of the air-cooled condenser 200 is too large, the evaporative condenser 100 is started, the evaporative condenser 100 precools and cools the refrigerant, and according to the principle of thermal expansion and cold contraction, when the temperature of the refrigerant is reduced, the volume of the gaseous refrigerant is contracted, the pressure of the refrigerant in the refrigerant pipeline 300 is reduced, so that the temperature and the pressure of the refrigerant entering the air-cooled condenser 200 are reduced, and the problem that the outdoor unit of the air conditioner frequently gives an alarm at high temperature and high pressure is solved. Simultaneously, compare in direct surface at air cooled condenser and spray, through the mode that increases evaporative condenser 100 in this application, can prevent that air cooled condenser 200 from being in the damp and hot environment, and then reduce the probability that air cooled condenser 200 corrodes the damage, promote air cooled condenser 200's security, promote air condensing units's life-span.
In this application "turn on the evaporative condenser" means: starting a first circulating water pump 16 and a spraying device 13 of the evaporative condenser 100, and simultaneously starting a first fan 19; the first circulating water pump 16 extracts cooling water from the water receiving tray 15 and sprays the cooling water to the surface of the heat exchange coil 14 through the spraying device 13, and the high-temperature and high-pressure refrigerant and the spraying water exchange heat through the pipe wall of the heat exchange coil 14; the first fan 19 drives the airflow to flow from bottom to top to contact spray water on the pipe wall of the heat exchange coil 14, so that the evaporation speed of the spray water is increased; the flow direction of the spray water is opposite to the flow direction of the gas, so that the contact time and the contact area of the spray water and the heat exchange coil 14 can be prolonged, and the heat exchange efficiency of the evaporative condenser 100 is improved. Because the air current flow direction is opposite with the shower water flow direction, the air current can play the effect for the shower water cooling, and then reduces the temperature in the water collector. The water baffle 12 is located above the spraying device 13, and can effectively prevent the air flow from bringing the sprayed water out of the shell 11, so that the evaporative condenser 100 forms a closed water circulation, and the water replenishing requirement of the evaporative condenser 100 is reduced.
In some embodiments, for example, the air-cooled condenser 200 may be a finned tube heat exchanger including at least one finned tube and a heat dissipation fan for dissipating heat from the finned tube, the communication with the air-cooled condenser being the communication with the finned tube of the air-cooled condenser 200; in the present application, the type and structure of the air-cooled condenser 200 are not specifically limited,
referring to fig. 1, in some embodiments, the air conditioning system further comprises: the bypass pipeline 20 is arranged outside the shell 11 and is connected with the heat exchange coil 14 in parallel, and the bypass pipeline 20 is provided with a first control valve 21; the number of the second control valves 22 is two, and the two second control valves 22 are respectively arranged at two ends of the heat exchange coil 14. When the condensing pressure of the air-cooled condenser 200 is greater than the preset value and the evaporative condenser 100 needs to be started, the two second control valves 22 are started, the first control valve 21 is closed at the same time, and the refrigerant flowing from the compressor flows into the air-cooled condenser after being subjected to temperature reduction treatment by the evaporative condenser 100. When the condensing pressure of the air-cooled condenser 200 is lower than the preset value and the evaporative condenser 100 does not need to be opened, the first control valve 21 is opened and the two second control valves 22 are closed, and at the moment, the refrigerant flows from the bypass pipeline 20 and directly flows into the air-cooled condenser 200. If the bypass line 20 is not provided, when the evaporative condenser 100 does not need to be started, the first circulating water pump 16, the spraying device 13 and the first fan 19 of the evaporative condenser 100 are only required to be turned off. Compared with the case that the bypass pipeline 20 is not arranged, the refrigerant circulation system has the advantages that when the evaporative condenser 100 does not need to be started, the flow path of the refrigerant in the refrigerant loop is shortened, the energy consumption of the refrigerant in the flow process of the refrigerant in the refrigerant loop is reduced, and the operation energy consumption of the air conditioning system is reduced.
In some embodiments, the air conditioning system further includes a control system (not shown) including a pressure sensor (not shown) and a controller (not shown). The pressure sensor is configured to detect a condensing pressure value of the air-cooled condenser 200, that is, the pressure sensor is disposed at a refrigerant inlet of the air-cooled condenser, and detects a pressure value of the refrigerant entering the air-cooled condenser 200. The controller is electrically connected to the first fan 19, the first circulating water pump 16, the first control valve 21, the second control valve 22, and the pressure sensor, respectively, and is configured to control opening or closing of the first fan 19, the first circulating water pump 16, the first control valve 21, and the second control valve 22 according to a pressure value measured by the pressure sensor. For example, when the pressure value measured by the pressure sensor is greater than a certain threshold (for example, 18 kg), it is proved that the condensing pressure of the air-cooled condenser 200 is greater, and the evaporative condenser 100 needs to be turned on for auxiliary cooling, the controller controls the first fan 19, the first circulating water pump 16 and the second control valve 22 to be turned on, and controls the first control valve 21 to be turned off. When the pressure value measured by the pressure sensor is smaller than a certain threshold (for example, 16 kg), the condensing pressure of the air-cooled condenser 200 is lower, and the evaporative condenser 100 does not need to be started for auxiliary cooling, the controller controls the first fan 19, the first circulating water pump 16 and the second control valve 22 to be closed, and controls the first control valve 21 to be opened.
In some embodiments, the first circulating water pump 16 is an inverter pump, the first fan 19 is an inverter fan, and the controller is further configured to control the rotation speed of the first fan 19 and the first circulating water pump 16 according to the pressure value measured by the pressure sensor. The rotation speeds of the first fan 19 and the first water circulating pump 16 are positively correlated with the condensation pressure value of the air-cooled condenser measured by the pressure sensor, and the larger the pressure value is, the faster the rotation speeds of the first fan 19 and the first water circulating pump 16 are controlled by the controller.
In some embodiments, heat exchange coil 14 is made of copper tubing. When it is to be understood that, the heat exchange coil 14 of the evaporative condenser 100 is usually made of a material that is not easy to rust because it needs to be in contact with water, and meanwhile, the heat exchange coil 14 needs to exchange heat with shower water, so a material with good thermal conductivity is usually used; in summary, the heat exchanging coil 14 can also be made of other materials, and for example, the material of the heat exchanging coil 14 can also be carbon steel, low alloy steel, stainless steel, copper-nickel alloy, aluminum alloy, titanium, and the like.

The evaporative condenser 100 during operation can cool down the spray water, and the spray water after the cooling leads to the air intake department of air-cooled condenser 200 through the cooling return circuit, and the air inlet of air-cooled condenser 200 can cool down with the heat transfer of precooling coil 23 earlier, then with the condenser heat transfer, can promote the heat exchange efficiency of air-cooled condenser 200, reduces the condensing pressure of air-cooled condenser 200.
