Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning heat exchange, in particular to an air-conditioning heat exchange device. Background Art

[0002] The outdoor unit of a split air conditioner is a condenser in cooling mode and an evaporator in heating mode. At present, the outdoor units of air conditioners are all air-cooled, that is, the refrigerant flowing through the coil exchanges heat with the outdoor air. This has the following disadvantages:

[0003] 1. The manufacturing cost is high. In addition, there are installation costs, such as basic installation fees, drilling fees, bracket fees, and some even require high-altitude operation fees, extended copper pipe material fees, etc. This is a considerable expense;

[0004] 2. The operation of the fan that makes the outdoor air flow and heat exchange requires a certain amount of energy consumption;

[0005] 3. Large and heavy, which is an unavoidable disadvantage of air cooling;

[0006] 4. Allow outdoor air to exchange heat with the refrigerant. The greater the temperature difference between indoor and outdoor, the greater the energy consumption of the air conditioner.

[0007] 5. The heat in the room and the heat generated by the consumed electricity are transported to the outside, causing heat pollution to the environment and aggravating the urban heat island effect;

[0008] 6. When installed outdoors, the coils and fins are prone to accumulate dust. If dust is not removed, the heat exchange efficiency will be reduced. In addition, they are exposed to the sun and rain for many years, which will easily cause rust and aging, and also affect the appearance of the exterior wall of the house.

[0009] In order to solve the above problems, some people have proposed a number of air-conditioning water heat exchange devices set indoors, such as the air-conditioning indoor water pipe heat exchange device with announcement number CN2499741Y, which uses groundwater as a heat exchange medium, effectively reducing the energy consumption of the air conditioner, not only eliminating the axial flow fan that occupies most of the space in the outdoor unit, but also eliminating the electricity consumed by part of its power distribution system; another example is the water-cooled integrated air conditioner with announcement number CN2442152Y, which is composed of an indoor air heat exchange device, a compression device, auxiliary components, a water cooling device, water supply and drainage pipes, etc., and can form two structural forms of fixed and mobile types, with the advantages of compact structure, easy installation, flexible use, good cooling and heating effect, low noise, no thermal pollution to the environment, power saving, energy saving, convenient maintenance, and clever condensate treatment. However, the heat exchange tube structure in the above scheme is simply set, the heat exchange efficiency is low, especially the cooling water has no temperature control and adjustment, so it is necessary to improve the existing air-conditioning heat exchange device. Summary of the invention

[0010] The utility model aims to provide an air-conditioning heat exchange device, which solves the technical problems of low heat exchange efficiency and no temperature control and adjustment of cooling water in traditional air-conditioning heat exchange devices.

[0011] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is:

[0013] Furthermore, the coil is a copper tube wound into a structure of multiple spiral layers, a larger spiral layer is sleeved outside a smaller spiral layer, there are gaps between the spiral layers, and the beginning and the end of each spiral layer are connected in sequence.

[0014] Furthermore, the controller is provided with a first display screen and a temperature adjustment unit, the first display screen includes a first temperature display unit and a second temperature display unit, the first temperature display unit displays the real-time temperature of the cooling water detected by the temperature sensing head, and the second temperature display unit displays the temperature setting value of the cooling water set by the temperature adjustment unit.

[0015] Furthermore, the temperature adjustment part is a button-type adjustment or a knob-type adjustment. The button-type adjustment has a "+" key for setting the temperature to rise and a "-" key for setting the temperature to fall, and the knob-type adjustment has a temperature scale marking.

[0016] Furthermore, the temperature controller also includes a remote control, which is provided with an infrared transmitter, and the controller is provided with an infrared receiver, and the infrared receiver can receive the control signal transmitted by the infrared transmitter; the remote control is provided with a second display screen and a temperature adjustment button, and the second display screen displays the temperature setting value of the cooling water set by the temperature adjustment button; the temperature adjustment button has a "+" key for setting the temperature to rise and a "-" key for setting the temperature to fall.

[0017] Due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0018] 1. The utility model is connected with the indoor unit of the air conditioner and installed indoors for use. The pressure of tap water is used to make the water in the water tank flow and exchange heat. When the air conditioner is cooling, the cooling water in the water tank absorbs the heat of the refrigerant in the coil and the temperature rises. When the temperature sensing head detects that the temperature of the cooling water reaches the temperature setting value, the controller instructs the solenoid valve to open, and the tap water with a lower temperature enters the water tank, so as to achieve the air conditioner cooling heat exchange and obtain hot water of a specific temperature; Based on the above, by providing a spiral heat exchange tube, the heat exchange area can be increased and the heat exchange efficiency can be improved. By providing a thermostat, the water outlet temperature setting can be achieved, so as to solve the technical problems of low heat exchange efficiency and no temperature adjustment control of cooling water in traditional air conditioner heat exchange devices. By providing a multi-layer spiral heat exchange tube, the heat exchange area is further increased and the heat exchange efficiency is improved. By providing a button-type, knob-type and remote control thermostat, it is convenient to use in different scenes and meet different needs.

[0019] 2. The utility model changes the original method of using a fan to make outdoor air flow for heat exchange, and uses the pressure of tap water to make water flow for heat exchange, which not only reduces the cost generated by installing the fan, but also reduces the energy consumption generated by the operation of the fan, and also greatly reduces its size.

[0020] 3. The function of the utility model is the same as that of the existing air-conditioning outdoor unit, except that it uses indoor tap water for heat exchange, so it can be installed indoors, and the air-conditioning indoor unit is changed from the current split type to a one-piece type like a refrigerator, which can save the fan and two connecting copper pipes with a rated length of 3m, saving material costs, especially saving a lot of installation costs, and can reduce costs to a large extent.

[0021] 4. The temperature of tap water is significantly lower than the outdoor temperature in midsummer and significantly higher than the outdoor temperature in severe winter. Using tap water for heat exchange can not only make its size small and exquisite, but also make the refrigerant condense or evaporate under a smaller temperature difference or under a smaller pressure, thereby reducing the power consumption of the compressor and making the air conditioner more energy-efficient. No matter how big the difference between indoor and outdoor temperatures is, the energy consumption of the air conditioner will not increase.

[0022] 5. When the air conditioner is in cooling mode, if 50℃ domestic hot water is needed, use the button, knob or remote control to set the cooling water temperature to 50℃. At this time, the air conditioner becomes an air-energy water heater.

[0023] 6. The heat exchange efficiency of water cooling is much higher than that of air cooling, and the specific heat of water is very large, so the tap water consumed is not much, nor is it completely wasted. The cooling water is not polluted and can still be recycled as domestic water, such as washing clothes, flushing toilets, etc.

[0024] 7. The utility model is installed indoors, free from sun and rain, free from dust accumulation, and has no frequently running parts such as fans, so it rarely fails, so it is durable and will not cause heat pollution to the environment.

[0025] 8. The coil of the utility model is formed by winding a copper tube, without welding and fins, and has a simple manufacturing process and low cost. BRIEF DESCRIPTION OF THE DRAWINGS
