Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology, and in particular to a fresh air kitchen air conditioning device. Background Technology

[0002] Existing air conditioners consist of interconnected components such as compressors, condensers, expansion valves, and evaporators. The drawback of this type of air conditioner is that after the high-temperature, high-pressure refrigerant is compressed by the compressor and enters the condenser, it is only cooled by the fan. The temperature of the refrigerant after cooling is still high, resulting in a high overall unit temperature. This can easily lead to malfunctions such as shutdown during use. Therefore, there is a need to design an air conditioner that can operate in higher ambient temperatures. Utility Model Content

[0003] The purpose of this utility model is to provide a fresh air kitchen air conditioning device to solve the problems existing in the background technology.

[0004] To solve this technical problem, the technical solution of this utility model is as follows: A fresh air kitchen air conditioning unit includes an outer casing, within which a compressor is housed. The compressor outlet is connected to a condenser inlet port via a high-pressure pipe, through which high-temperature, high-pressure refrigerant is transported. The condenser outlet port is connected to an evaporator inlet port via a capillary pipe, and the evaporator outlet port is connected to the compressor inlet port. A heat dissipation air inlet is located near the condenser end of the outer casing, and a cold air outlet is located near the evaporator end, with the heat dissipation air inlet and outlet connected. The outer casing also includes a cold air outlet connected to the cold air inlet. The unit is characterized by a water collection tank at the bottom of the evaporator, a continuously bent extension on the high-pressure pipe, the extension being placed within the water collection tank, and the water collection tank having an inlet and a outlet. The unit also includes a dual-shaft motor, with a first output end connected to a first impeller and a second output end connected to a second impeller. The first impeller is positioned opposite the condenser, and the second impeller is positioned opposite the evaporator.

[0005] This application features a water collection tank at the bottom of the evaporator to collect the condensate produced by the evaporator. A continuous bend is formed on the high-pressure pipe, and the bend is placed in the water collection tank. The high-temperature and high-pressure refrigerant in the high-temperature pipe first exchanges heat with the water in the water collection tank, which greatly reduces the temperature of the refrigerant and thus reduces the temperature of the entire refrigeration system, enabling the equipment to operate normally without tripping in a high-temperature environment of 60 degrees Celsius.

[0006] Preferably, the first impeller is a backward-curved centrifugal fan, and the second fan is a forward-curved centrifugal fan.

[0007] Preferably, a first air duct is formed between the first impeller and the condenser, and a second air duct is formed between the second fan and the evaporator. Both the first and second air ducts are designed with a foam insulation layer.

[0008] This results in better overall insulation performance, reducing the impact of high external temperatures on the machine's refrigeration system, enabling the present application to operate normally under ultra-high temperature conditions of 60 degrees Celsius.

[0009] Preferably, the bent portion of the high-temperature pipe is fixed to the bottom surface of the water collection tank by a fixing plate.

[0010] Preferably, the cold air outlet is provided on the outer casing near the side of the forward-inclined centrifugal fan.

[0011] Preferably, the evaporator is a balanced flow evaporator; the condenser is a balanced flow condenser. Compared with ordinary copper tube fins, the microchannel balanced flow structure has a system pressure that is 0.3 MPa lower, a weight that is 20% lighter, an energy efficiency that is 10% higher, and a cost that is about 30% lower.

[0012] Preferably, a solenoid valve is connected to the water inlet. When the outside temperature is higher than 35 degrees Celsius, the solenoid valve opens, allowing external water to replenish the water in the collection tank.

[0013] Among them, the high-pressure pipe is made of conductors with relatively high heat transfer efficiency, such as copper and aluminum alloy.

[0014] The beneficial effects of the above technical solution and this utility model are: This application features a water collection tank at the bottom of the evaporator to collect the condensate produced by the evaporator. A continuous bend is formed on the high-pressure pipeline, and the bend is placed inside the water collection tank. The high-temperature and high-pressure refrigerant in the high-temperature pipeline first exchanges heat with the water in the water collection tank, which greatly reduces the temperature of the refrigerant and thus reduces the temperature of the entire refrigeration system. This allows the equipment to operate normally without shutting down in a high-temperature environment of 60 degrees Celsius. Furthermore, the dual-output shaft motor reduces the weight of the equipment during hoisting and reduces the overall power consumption of the machine. Attached Figure Description

The condenser outlet port 4 is connected to an evaporator 200 liquid inlet port 5 via a capillary tube, and the evaporator outlet port 6 is connected to the compressor inlet port 7. A heat dissipation air inlet 8 is located near the condenser end of the outer casing, and a cold air outlet 9 is located near the evaporator end. The heat dissipation air inlet 8 and the heat dissipation air outlet 9 are connected, and the outer casing near the evaporator end... The evaporator has a cold air inlet 10 and a cold air outlet 11 connected to the cold air inlet. A water collection tank 12 is provided at the bottom of the evaporator. A continuously bent extension 112 is formed on the high-pressure pipe, and the extension is placed inside the water collection tank. The water collection tank has a water inlet 13 and a water outlet 14. It also includes a dual-shaft motor 15.

Dust filters are provided on both the heat dissipation inlet and the cold air inlet sides; this is prior art and will not be described further.

[0019] This application features a water collection tank at the bottom of the evaporator to collect the condensate produced by the evaporator. A continuous bend is formed on the high-pressure pipe, and the bend is placed in the water collection tank. The high-temperature and high-pressure refrigerant in the high-temperature pipe first exchanges heat with the water in the water collection tank, which greatly reduces the temperature of the refrigerant and thus reduces the temperature of the entire refrigeration system, enabling the equipment to operate normally without adjustment in a high-temperature environment of 60 degrees Celsius.

[0020] Specifically, the first impeller is a backward-curved centrifugal fan, the second impeller is a forward-curved centrifugal fan, the first impeller and the condenser form a first air duct 18, the second impeller and the evaporator form a second air duct 19, and the first air duct and the second air duct are designed with a foam insulation layer 20.

[0021] This results in better overall insulation performance, reducing the impact of high external temperatures on the machine's refrigeration system, enabling the present application to operate normally under ultra-high temperature conditions of 60 degrees Celsius.

[0022] The bent portion of the high-temperature tube is fixed to the bottom surface of the water collection tank by a fixing plate 21. The cold air outlet is located on the outer casing near the side of the forward-inclined centrifugal fan. The evaporator is a balanced flow evaporator; the condenser is a balanced flow condenser. Compared with ordinary copper tube fins, the microchannel balanced flow structure has a system pressure 0.3 MPa lower, is 20% lighter, has 10% higher energy efficiency, and is about 30% cheaper. A solenoid valve 23 is connected to the water inlet. When the outside temperature is higher than 35 degrees Celsius, the solenoid valve opens, and external water is introduced to replenish the water in the water collection tank.
