Description

Water-cooling mobile air conditioner without exhaust pipe

Technical Field

The utility model relates to the technical field of air conditioners, in particular to a water-cooling mobile air conditioner without an exhaust pipe.

Background

The outdoor unit of the split air conditioner is integrated in the indoor unit by the mobile air conditioner, so that the trouble and danger of installing and detaching the outdoor unit are avoided, and the mobile air conditioner is one of main advantages of the mobile air conditioner relative to the split air conditioner. However, the conventional mobile air conditioner (single-cooling type or cold-warm type) usually has a very thick exhaust pipe at the back of the case and leads to the outside of the window. The mobile air conditioner with the exhaust pipe cannot be moved at will, and windows in some rooms are inconvenient or even impossible to install, so that people want to find a method for removing the exhaust pipe.

The invention patent 'an energy-saving environment-friendly water-cooling mobile air conditioner' 201910996836.4 is a mobile air conditioner without a compressor and a refrigerant, and the water is sprayed on an evaporative wet curtain to cool through the cooperation of a water delivery mechanism and a water return mechanism, so that the cooling effect is limited (the cooling effect is poorer than that of the mobile air conditioner with the compressor and the refrigerant), and the mobile air conditioner can not heat.

The invention patent 'mobile water-cooled air conditioner' 202310652227.3 adopts the working principles of compressor, refrigerant, circulating water tank and circulating water pump to make refrigeration. The circulating water tank has three working modes. Mode 1 (closed mode): after the circulating water tank is fully filled with cold water once, the water inlet valve and the water outlet valve of the circulating water tank are continuously closed. Because the water temperature of the circulating water tank is higher and higher, the continuous refrigeration time is limited by the capacity of the water tank, and the circulating water tank is suitable for short-time emergency use. Mode 2 (semi-closed mode): the external water source enters the circulating water tank to supplement water through the control of the water inlet of the circulating water tank and the electromagnetic valve, warm water gradually stored in the circulating water tank is discharged through the control of the water outlet and the electromagnetic valve, the electromagnetic valve is controlled by the singlechip, and the automatic opening and closing of the electromagnetic valve are controlled according to the temperature difference set value between the water inlet temperature sensor and the water outlet temperature sensor. Mode 3 (open mode): the water inlet valve of the circulating water tank is communicated with a water source outside the air conditioning tank, and the electric control module controls the water inlet valve and the water outlet valve of the circulating water tank to be continuously opened, so that the water consumption is high. It is also not possible to heat.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In fig. 1, casters 18 for an air conditioner moving device are installed below an air conditioner case 1, and a display and operation panel 6 is installed above the air conditioner case 1. When refrigeration is selected through the display and operation panel 6, the electric control device 11 controls the port A and the port B of the electromagnetic four-way valve 3 to be communicated, and the port C and the port D to be communicated; after being compressed into high-temperature high-pressure gas by the compressor 2, the refrigerant is conveyed to the condenser 12 through the port A and the port B of the electromagnetic four-way valve 3, is subjected to non-contact heat exchange with water in the water tank 13, is throttled and decompressed by the throttle valve 8, becomes low-temperature low-pressure liquid, and is conveyed to the evaporator 5; the refrigerant exchanges heat with the air input from the outside of the case 1 in the evaporator 5to become low-temperature low-pressure gas, and then returns to the compressor 2 through the C port and the D port of the electromagnetic four-way valve 3 to complete a refrigeration cycle. Meanwhile, the indoor hot air is cooled by the evaporator 5 and then sent out by the fan 7. The working principle is similar to that of a common household refrigeration air conditioner, the condenser 12 is cooled by water, an exhaust pipe is not needed to bring heat generated by the condenser 12 out of a window for cooling, and an outdoor unit is not needed. As the water temperature of the water tank 13 becomes higher and higher, the hot water near the condenser 12 is diffused as soon as possible by using the water mixer 10, so that the water temperature of the water tank 13 is uniform as soon as possible. When the temperature sensor 9 detects that the water temperature reaches the set value W1, the working surface of the heat exchange device 16, which is close to one side of the condenser 12, starts to refrigerate so as to reduce the water temperature; when the water temperature decreases to the set value W2, the heat exchanging device 16 stops operating. The condensed water generated by the evaporator 5 is collected by the water collecting tray 4 and then directly collected into the water tank 13. When the air conditioner is used for the first time or the water level in the water tank 13 is low, a proper amount of water needs to be added into the water tank 13, and when the water level sensor 15 detects that the water level in the water tank 13 reaches the set value Z1, the alarm prompt of the operation panel 6 is displayed, and the water addition is stopped. When the water level sensor 15 detects that the water level in the water tank 13 exceeds the set value Z1, the operation panel 6 gives an alarm and prompts to discharge water, and at the moment, the water outlet 17 is preferably opened to discharge part of water. When the water level in the water tank 13 is lower than the set value Z2, the display and operation panel 6 gives an alarm to prompt water addition, and water can be added through the water inlet 14 at the moment.

When heating is selected by moving the air conditioner display and operation panel 6, the electric control device 11 controls the port A and the port C of the electromagnetic four-way valve 3 to be communicated, and the port B and the port D to be communicated; the refrigerant is compressed into high-temperature high-pressure gas by the compressor 2, is conveyed to the evaporator 5 through the port A and the port C of the electromagnetic four-way valve 3, is changed into low-temperature low-pressure liquid by the throttle valve 8, and is then conveyed to the condenser 12; after the heat exchange (heat absorption of the refrigerant) between the refrigerant in the condenser 12 and the water in the water tank 13 is completed, the refrigerant is changed into low-temperature low-pressure gas, and the low-temperature low-pressure gas returns to the compressor 2 through the port B and the port D of the electromagnetic four-way valve 3, so that a heating cycle is completed. The working principle is similar to that of a common household heating air conditioner, only water is absorbed to remove heat and cool, and the exhaust pipe is not needed to bring the cold generated by the condenser 12 out of the window, and an outdoor unit is not needed. As the water temperature of the water tank 13 becomes lower and lower, the cold water near the condenser 12 is diffused as soon as possible by using the water mixer 10, so that the water temperature of the water tank 13 is uniform as soon as possible. When the temperature sensor 9 detects that the water temperature reaches a set value W3, the electric control device 11 controls the working surface of the heat exchange device 16, which is close to one side of the condenser 12, to start heating so as to increase the water temperature; when the water temperature rises to the set value W4, the heat exchanging device 16 stops operating.

In fig. 2, the heat exchange device 16 mainly includes a semiconductor refrigeration sheet 20, a cold guide 19, a radiator 21, and a fan 22. The semiconductor refrigerating sheet 20 can adopt a TEC1-12706 type refrigerating sheet or a higher-power type (according to the size of the water tank), two leads of the refrigerating sheet are respectively connected with the positive electrode and the negative electrode of a 12V (according to the type of the refrigerating sheet) power supply, one surface of the refrigerating sheet is cooled, the other surface is heated, and the refrigerating sheet is known by one touch; if the positive electrode and the negative electrode are connected reversely, the cold surface and the hot surface are exchanged. In general, when a red lead of a refrigerating sheet is connected to a positive electrode and a black lead is connected to a negative electrode, a cold face (with a literal) is cooled after a few seconds of power is applied, and a hot face (without a literal) is heated. Therefore, by selecting the cooling or heating button on the display and operation panel 6, the semiconductor cooling fin working surface on the side close to the condenser 12 can be selected to start cooling or heating. When the heat exchange device 16 is installed, the heat conduction silicone grease is uniformly coated on two sides of the semiconductor refrigeration piece 20, then the semiconductor refrigeration piece 20 is tightly attached to the cold guide 19 and the radiator 21, then the cold guide 19, the radiator 21 and the fan 22 are connected through screws, and finally the cold guide 19 is installed on the water tank 13 in a sealing way.

In the present utility model, since the power of the fan 22 is much smaller than that of the fan 7 for front blowing and the fan 22 is installed at the back of the mobile air conditioner, although the hot air (during cooling) or the cold air (during heating) blown out by the fan 22 remains in the room, the reaction to the cold air (during cooling) or the hot air (during heating) blown out by the front of the mobile air conditioner is limited; second, the power of the fan 22 is much smaller than that of the exhaust duct behind the conventional mobile air conditioner, so that the fan 22 blows out much smaller amount of hot air or cold air than the exhaust duct.

The foregoing description of the preferred embodiments of the utility model has been presented only in a specific and detailed description, and is not to be construed as limiting the scope of the utility model. It should be noted that modifications and improvements can be made by those skilled in the art without departing from the spirit of the utility model, and the utility model is intended to encompass such modifications and improvements.
