Description

Technical Field

[0001] The utility model belongs to the technical field of air-conditioning equipment, and in particular relates to a mobile post air-conditioner which recycles condensed water. Background Art

[0002] In large industrial plants, outdoor activities, temporary buildings and other places, it is not suitable to install ordinary air conditioners or central air conditioners because the space is too large and too high, resulting in a poor working environment for operators. The hot summer plus the heat generated by the machine itself makes the temperature in the operating environment as high as 40°C or above. The continuous high temperature environment not only affects work efficiency, but also is not conducive to the physical and mental health of employees, and also affects the stability and service life of machinery and equipment. Therefore, mobile post air conditioners came into being. Mobile post air conditioners are cooling equipment that can maintain a relatively low temperature cold island in a relatively hot environment to achieve local cooling, which can effectively improve the working environment of personnel.

[0003] On the other hand, the mobile station of the prior art is to install the condenser and the evaporator together in the unit body, and the refrigerant pipeline connects the compressor, condenser, evaporator, and throttling element in sequence to form a refrigeration cycle system to achieve local cooling.

[0004] The Chinese invention patent with patent publication number CN112066461A and publication date of December 11, 2020, discloses a mobile air source post air conditioner, the structure of which includes a unit box, an exhaust port on the top of the unit box, an exhaust pipe connected to the exhaust port, and several air conditioning air supply ports on the front of the unit box. The unit box has a built-in refrigeration unit, an exhaust fan and an air-conditioning fan. The refrigerant outlet of the compressor of the refrigeration unit is connected to the condenser through a four-way valve. The condenser is placed near the air inlet of the unit box. The exhaust fan inhales natural air to cool the condenser. The air outlet of the exhaust fan is connected to the exhaust port. The refrigerant of the compressor is connected to the high-pressure tank through a conversion valve. The outlet of the high-pressure tank is connected to the tube side of the evaporator through a filter and an expansion valve. Natural air passes through the shell side of the evaporator and then exchanges heat with the refrigerant in the shell side before entering the air-conditioning fan. The air-conditioning fan delivers cold air to the air-conditioning air supply port.

[0005] The general structural principle of the mobile air source position air conditioner in this invention patent is as follows: after the unit is turned on, the compressor runs, and the air flows through the condenser through the four-way valve. The exhaust fan inhales natural air to cool the condenser. The elevated exhaust gas is discharged through the exhaust port. The refrigerant enters the high-pressure tank through the conversion valve. The refrigerant in the high-pressure tank passes through the filter and enters the evaporator through the expansion valve. The air-conditioning fan works, and the inhaled natural air flows through the evaporator. The evaporator absorbs the heat of the air and converts it into cold air of 5-15 degrees, which is delivered to the working area by the air-conditioning fan.

[0006] However, in actual use, the mobile air source post air conditioner still has at least the following two shortcomings, in other words, which are the technical problems to be solved by the present utility model.

[0007] 1. There is no partition between the exhaust port and the supply port, which leads to heat exchange between the unit's evaporation heat exchange cold air channel and the condensation heat exhaust channel, reducing the refrigeration effect and affecting the heat dissipation effect of the equipment.

[0008] 2. The condensed water is not used properly, resulting in a waste of resources.

[0009] So to sum up, there is an urgent need for a new type of mobile workplace air conditioner that can isolate hot and cold channels and recycle condensed water. Utility Model Content

[0010] The utility model provides a mobile post air conditioner that recycles condensed water. By arranging a hot and cold channel partition unit and a circulating supercooling unit on a chassis body, the following can be achieved: 1. The hot and cold channel partition unit isolates the condenser that discharges hot air and the evaporator that discharges cold air, thereby avoiding the influence of heat exchange between the unit's evaporation heat exchange cold air channel and the condensation heat exhaust channel on the refrigeration effect, and classifies and arranges them functionally to reduce interference between equipment and improve equipment operation efficiency and heat dissipation effect; 2. By arranging the circulating supercooling unit, the condensed water formed after the evaporator absorbs heat is recycled and utilized, so as to be used for cooling the refrigerant entering the condenser, thereby improving the heat dissipation efficiency of the condenser.

[0011] The technical solution adopted by the utility model to solve the above-mentioned problem is: a mobile post air conditioner that recycles condensed water, the structure of which includes a chassis body, a compressor, a condenser, a front pipe of the condenser, a rear pipe of the condenser, and an evaporator, and also includes a cold and hot channel partition unit arranged in the chassis body and used to separate the condenser and the evaporator, and a circulating supercooling unit arranged in the chassis body and used to cool the front pipe of the condenser by receiving condensed water on the evaporator.

[0012] A further preferred technical solution is that the circulating supercooling unit includes a water receiving pan arranged below the evaporator, a water circulation pump connected to the water receiving pan, and a spray cooler connected to the water circulation pump and used to cool the front pipeline of the condenser.

[0013] A further preferred technical solution is that the circulating supercooling unit also includes a sleeve-type cooler which is sleeved between the water receiving pan and the water circulating pump and is used to cool the rear pipeline of the condenser.

[0014] A further preferred technical solution is that the hot and cold channel partition unit includes a heat insulating vertical plate.

[0015] A further preferred technical solution is that the number of the thermal insulation vertical panels is two.

[0016] A further preferred technical solution is that the hot and cold channel partition unit also includes waterproof thermal insulation cotton arranged between the two layers of the thermal insulation vertical plates.

[0017] A further preferred technical solution is that the circulating supercooling unit also includes a water storage tank arranged between the spray cooler and the jacketed cooler.

[0018] A further preferred technical solution is that the circulating supercooling unit also includes a filter plate arranged on the water receiving tray.

[0019] A further preferred technical solution is that the spray cooler includes a condenser housing, a water distribution coil disposed on the condenser housing, a spray head disposed on the water distribution coil, and a water collection tray disposed at the bottom of the condenser housing.

[0020] A further preferred technical solution is that the sleeve-type cooler includes a condensate jacket, which is arranged on the condensate jacket and used to connect to the condensate inlet of the water receiving pan, and a condensate outlet which is arranged on the condensate jacket and used to connect to the spray cooler.

[0033] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0034] As attached Figure 1-7 As shown, a mobile post air conditioner for recycling condensed water comprises a chassis body 11, a compressor 12, a condenser 13, a condenser front pipe 14, a condenser rear pipe 15, and an evaporator 16, and also comprises a hot and cold channel partition unit 1 arranged in the chassis body 11 and used to separate the condenser 13 and the evaporator 16, and a circulating supercooling unit 2 arranged in the chassis body 11 and used to cool the condenser front pipe 14 by receiving condensed water on the evaporator 16.

[0035] In this embodiment, the refrigeration system of the mobile post air conditioner that circulates condensed water mainly utilizes the heat absorption and heat release characteristics of the refrigerant, and completes refrigeration through the four major refrigeration components (compressor, condenser, evaporator and throttle valve). The refrigeration process is: the compressor 12 compresses the gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant (60°C-80°C) and transmits it to the condenser 13 through the condenser front pipeline 14. The refrigerant releases heat, cools and liquefies in the condenser 13. After heat dissipation, it becomes a liquid refrigerant at room temperature and high pressure (about 50°C), and then passes through the condenser 13. After passing through the condenser, the pipeline 15 connects the condenser 13, the throttling element 21 and the evaporator 16 in sequence. After the refrigerant passes through the throttling element 21 and enters the evaporator 16, the space suddenly increases and the pressure decreases, and the liquid refrigerant will vaporize and become a gaseous low-temperature refrigerant (about 0℃-10℃), thereby absorbing a large amount of heat, and the evaporator 16 will become cold. The blower 20 blows the indoor air through the evaporator 16 and turns it into cold wind, and the gaseous low-temperature refrigerant is transported back to the compressor 12.

[0036] In addition, the chassis body 11 is provided with condensation air inlet grilles and evaporation air inlet grilles on both sides close to the condenser 13 and the evaporator 16, respectively. The top of the chassis body 11 is provided with one or more exhaust ducts 17, and the exhaust duct 17 adopts a corrugated air duct that can be freely retracted and turned. The exhaust fan 18 is arranged at the top of the chassis body 11 and below the exhaust duct 17. The exhaust fan 18 discharges the hot air gas after the heat release of the condenser 13 to the indoor high altitude or the outdoors through the exhaust duct 17; the front top of the chassis body 11 is inclinedly provided with an air outlet panel for setting the air outlet 19, and the air outlet 19 adopts a spherical jet nozzle with adjustable angle, which can greatly increase the air supply distance and air supply angle, and the air supply fan 20 sends the cold air cooled by the evaporator 16 to the cooling area through the air outlet 19. The chassis body 11 is provided with universal wheels 22 for easy movement.

[0037] In addition, since the condenser 13 is a heat release process and discharges hot air, the condenser 13, the exhaust fan 18 and the air outlet 19 form a condensation heat exhaust channel; the evaporator 16 is a heat absorption process and discharges cold air, the evaporator 16, the air outlet 19 and the air supply fan 20 form an evaporation heat exchange cold air channel, so the hot and cold channel partition unit 1 is set to separate the condenser 13 and the evaporator 16, so that the condensation heat exhaust channel and the evaporation heat exchange cold air channel are separated to avoid heat exchange between the two and affect the cooling effect.

[0038] Finally. Since the evaporator 16 contains a gaseous low-temperature refrigerant, which absorbs heat from the indoor gas, the water vapor in the air condenses into water droplets after encountering the evaporator 16, forming condensed water with a relatively low temperature. The temperature of the low-temperature condensed water is mostly around 10°C-20°C. The function of the circulating subcooling unit 2 is to recycle the low-temperature condensed water generated by the evaporator 16, and use the condensed water to cool the high-temperature and high-pressure refrigerant in the condenser front pipeline 14, thereby reducing the workload of the condenser 13 and improving the heat dissipation efficiency of the condenser 13.

[0039] The circulating subcooling unit 2 includes a water receiving pan 201 disposed below the evaporator 16, a water circulation pump 202 connected to the water receiving pan 201, and a spray cooler 203 connected to the water circulation pump 202 and used to cool the front pipe 14 of the condenser.

[0040] In this embodiment, the water receiving tray 201 is used to collect the low-temperature condensed water formed by condensation of the evaporator 16. The condensed water is then transmitted to the spray cooler 203 through the water circulation pump 202 for use, thereby cooling the high-temperature and high-pressure refrigerant in the front pipe 14 of the condenser. The condensed water after use can be directly discharged or recycled.

[0041] The circulating subcooling unit 2 further includes a jacketed cooler 204 which is sleeved between the water receiving tray 201 and the water circulating pump 202 and is used to cool the rear pipeline 15 of the condenser.

[0042] In this embodiment, the function of the sleeve cooler 204 is to perform secondary subcooling on the refrigerant in the condenser rear pipe 15 in the form of a jacket, thereby improving the refrigeration capacity. The refrigerant temperature in the condenser front pipe 14 is 60°C-80°C, and the refrigerant temperature in the condenser rear pipe 15 is about 50°C. Therefore, the sleeve cooler 204 can be used to cool the condensed water in the water receiving pan 201 to first cool the condenser rear pipe 15, and then cool the condenser front pipe 14, to achieve secondary cooling, improve the utilization rate of condensed water and the refrigeration effect of the unit.

[0043] The hot and cold channel partition unit 1 includes a heat insulating vertical plate 101 .

[0044] In this embodiment, the heat-insulating vertical plate 101 is made of waterproof and heat-insulating material to prevent the condensation heat exhaust channel and the evaporation heat exchange cold air channel from performing heat exchange and affecting the cooling effect.

[0045] The number of the thermal insulation vertical panels 101 is two.

[0046] In this embodiment, the thermal insulation vertical plate 101 is provided with two layers to increase the thermal insulation effect, and the thermal insulation cavity formed by the two layers of the thermal insulation vertical plate 101 makes the thermal insulation effect better.

[0047] The hot and cold channel partition unit 1 also includes a waterproof heat-insulating cotton 102 arranged between two layers of the heat-insulating vertical plates 101 .

[0048] In this embodiment, the waterproof heat-insulating cotton 102 can be arranged in the heat-insulating cavity formed by the two layers of the heat-insulating vertical panels 101 to further increase the heat-insulating and waterproof capabilities, and at the same time can effectively reduce the noise of the mobile post air conditioner that recycles condensed water to a certain extent.

[0049] The circulating supercooling unit 2 further includes a water storage tank 205 disposed between the spray cooler 203 and the jacket cooler 204 .

[0050] In this embodiment, the water storage tank 205 serves to store the condensed water in the water receiving tray 201. At the same time, the water storage tank 205 can be cyclically connected to the spray cooler 203 to prevent the evaporator 16 from producing less condensed water and affecting the cooling effect of the spray cooler 203. Moreover, when the mobile post air conditioner that recycles condensed water is turned on, the evaporator 16 produces less condensed water, so some low-temperature water can be poured into the water storage tank 205 in advance for cooling.

[0051] The circulating supercooling unit 2 further includes a filter plate 206 disposed on the water receiving tray 201 .

[0052] In this embodiment, indoor air needs to enter the chassis body 11 and be cooled and condensed into condensed water by the evaporator 16. There are many dust and other substances in the air. After condensation, it flows back to the water receiving tray 201, which is easy to block the pipeline and affect the normal operation of the equipment. Therefore, the filter plate 206 is provided to filter it.

[0053] The spray cooler 203 includes a condenser housing 203a, a water-distributing coil 203b disposed on the condenser housing 203a, a spray head 203c disposed on the water-distributing coil 203b, and a water collecting tray 203d disposed at the bottom of the condenser housing 203a.

[0054] In this embodiment, the condenser box 203a is connected to the condenser front pipe 14 by fins, the water uniformizing coil 203b is arranged on the top of the condenser box 203a and is connected to the condensed water, and a plurality of the spray heads 203c are arranged on the water uniformizing coil 203b to cool the condenser front pipe 14, and the water collecting tray 203d is used to collect the condensed water sprayed by the spray heads 203c.

[0055] The jacket cooler 204 includes a condensate jacket 204a, a condensate inlet 204b disposed on the condensate jacket 204a and used to connect to the water receiving tray 201, and a condensate outlet 204c disposed on the condensate jacket 204a and used to connect to the spray cooler 203.

[0056] In this embodiment, the condensate jacket 204a is jacketed on the condenser rear pipe 15, and the water receiving tray 201 flows into the condensate jacket 204a through the condensate inlet 204b under gravity, so that the low-temperature condensate cools the condenser rear pipe 15, and the condensate then flows into the spray cooler 203 from the condensate outlet 204c.

[0057] The above is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the utility model. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the utility model.
