Description

Technical Field

[0001] This utility model mainly relates to the field of refrigeration and air conditioning equipment technology, specifically a long-distance air supply dehumidifier. Background Technology

[0002] As we all know, the temperature of the air outlet of a modern evaporative air cooler is inconsistent with the outlet temperature after the air is delivered through the air duct. The longer the air duct, the greater the temperature drop at the outlet, making it difficult to control. When an evaporative air cooler outputs cold air, there will inevitably be make-up air. During the make-up air process, a large amount of hot and humid air will enter the refrigeration heat exchanger. High humidity air will easily increase the load on the refrigeration heat exchanger. If the cold air is output at a temperature below zero, it is more likely to cause frost to form on the low-temperature heat exchanger, which will seriously affect the cooling efficiency and the outlet air temperature.

[0003] Most modern evaporative air coolers supply the same amount of fresh air as they deliver. This significantly impacts the cooling capacity of the heat exchanger. To quickly process hot, humid fresh air, a sufficiently large heat exchanger and high cooling power are required. When a high-powered heat exchanger encounters low-velocity air, the heat exchanger frosts due to the low airflow. Another approach is to increase the fan speed for internal circulation to prevent low airflow, but this internal circulation cannot solve the problem of reduced pipe output temperature. Furthermore, the supplied air is not dehumidified; the hot, humid fresh air directly contacts the low-temperature heat exchanger, causing frost formation and severely affecting the outlet air temperature and cooling efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a long-distance air supply dehumidification air cooler.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

The blower is connected to the air supply duct, and the lower end of the air supply duct is connected to a connecting duct. The left side opening of the connecting duct has an air outlet and an air supply outlet, respectively. An air volume regulating valve and a one-way valve are respectively installed on the air outlet and the air supply outlet. The upper end of the connecting duct is connected to a fresh air and cold air mixing pipe. A condensate drain outlet is provided below the fresh air and cold air mixing pipe. A water-stop bell mouth is provided inside the fresh air and cold air mixing pipe. The fresh air and cold air mixing pipe is connected to an evaporator, and a return air channel is provided inside the evaporator.

[0007] The blower includes a fan, an air inlet box, and an impeller.

Detailed Implementation

[0013] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0014] like Figure 1 As shown, a long-distance air supply dehumidifier includes a blower 1 and an air supply duct 2. The blower 1 is connected to the air supply duct 2, and the air supply duct 2 is connected to the lower end of a connecting duct 3. The left side opening of the connecting duct 3 has an air outlet 4 and an air supply inlet 5, respectively. An air volume regulating valve 6 and a one-way valve 7 are respectively installed on the air outlet 4 and the air supply inlet 5. The upper end of the connecting duct 3 is connected to a fresh air and cold air mixing pipe 8. A condensate drain outlet 9 is provided below the fresh air and cold air mixing pipe 8. A water-stop bell mouth 10 is provided inside the fresh air and cold air mixing pipe 8. The fresh air and cold air mixing pipe 8 is connected to an evaporator 11, and a return air channel 12 is provided inside the evaporator 11.

[0015] Furthermore, the blower 1 includes a blower 13, an air inlet box 14, and an impeller 15.

[0016] Working principle:

[0017] The blower 1 delivers low-temperature air to the air supply duct 2. The air supply duct 2 outputs two paths. One path delivers low-temperature cold air to the air outlet 4 through the air volume regulating valve 5. The second path connects to the air supply port 5 and the fresh air and cold air mixing pipe through the connecting pipe 3. When the fresh air enters through the air supply port 5, it passes through the one-way valve 7. The one-way valve 7 prevents the low-temperature air supply in the connecting pipe 3 from overflowing due to excessive air volume. It mixes with the low-temperature air in the fresh air and cold air mixing pipe, and at the same time, it extracts the moisture in the fresh air. The condensate is stopped by the water stop bell 10. At the same time, the condensate is discharged through the condensate drain port 9. The dehumidified low-temperature and low-humidity air enters the evaporator 11 for cooling and then passes through the air duct 12 to the blower 1, forming a dehumidification and cooling air supply cycle.

[0018] Increase the fan airflow because long-distance air delivery causes the duct to absorb heat, raising the temperature of the outlet low-temperature air. Only by increasing the airflow can the temperature drop caused by the heat absorption of the duct be balanced. At the same time, excess cold air returns to the refrigeration heat exchanger for cooling. The supply air is high temperature and high humidity, while the excess air is low temperature. The high temperature and high humidity fresh air and the low temperature air share the same air duct, allowing them to mix together. This allows the moisture in the high temperature and high humidity to be extracted, achieving the purpose of dehumidification, extending the time for the refrigeration heat exchanger to frost, improving refrigeration efficiency, and reducing operating costs.
