Description

Technical Field

[0001] The utility model relates to the technical field of heat pipe dehumidification, in particular to a high-efficiency heat pipe dehumidification and energy-saving device for air conditioning in pharmaceutical workshops. Background Art

[0002] The second floor of the workshop houses eight standard air-conditioning units. Due to product process requirements, the ambient temperature and humidity must be strictly controlled during production, maintaining a constant temperature of 18-25°C and humidity ≤65%. During summer operation, the chillers supply cold water at 7-12°C. The incoming air is cooled to 13-15°C by the air conditioner's surface cooler, then heated by steam to a comfortable temperature of above 18°C, passing through the rear heater to meet the indoor temperature and humidity requirements for finished products.

[0003] However, under the high temperature and high humidity conditions in summer, the workshop refrigeration unit runs at full load, and the supply pressure to meet the standards is extremely high, with the risk of exceeding the standards; at the same time, the summer dehumidification mode doubles the waste of cold water cooling capacity and temperature control steam. Chinese patent application CN219656198U, published on 2023.09.08. A dehumidification and energy-saving device for clean air conditioning in pharmaceutical workshops is disclosed. It uses a dehumidification pre-cooling pipe to lower the temperature entering the surface cooler, reducing the load of the surface cooler originally used for sensible heat cooling. Although it improves the energy-saving efficiency to a certain extent, there is a problem that particulate impurities in the air enter the device with the airflow and are deposited on the surface of the heat exchange equipment, thereby causing the heat exchange efficiency to decrease. In addition, the existing device also has the problem of the setting of a U-shaped dehumidification and energy-saving module, which leads to an increase in air flow resistance. Utility Model Content

[0004] In view of the above deficiencies in the prior art, the purpose of the present invention is to provide a high-efficiency heat pipe dehumidification and energy-saving device for air conditioning in a pharmaceutical workshop. By setting a primary backwash filter and a secondary backwash filter, the air entering the U-shaped dehumidification and energy-saving module is removed from impurities, and the air is backwashed by the condensed water in the condensate collection tank, thereby avoiding the problem of particulate impurities entering the device with the air flow; by setting a pre-cooling heat pipe coil and a heat-conducting condensation net, the air resistance is reduced while minimizing the influence on the heat exchange efficiency. When used in conjunction with a reducing pipe, the air flow resistance is greatly reduced, thereby improving the heat exchange efficiency.

[0005] The utility model is realized by adopting the following technical solutions:

[0006] The pharmaceutical workshop air-conditioning high-efficiency heat pipe dehumidification and energy-saving device includes a U-shaped dehumidification and energy-saving module and a fan. The fan is connected to the baffle through a primary backwash filter, and the baffle is connected to the U-shaped dehumidification and energy-saving module. A pre-cooling heat pipe and a reheating heat pipe are arranged inside the U-shaped dehumidification and energy-saving module. A dehumidification cold coil is arranged between the pre-cooling heat pipe and the reheating heat pipe. The dehumidification cold coil is connected to the air-conditioning outlet, and the U-shaped dehumidification and energy-saving module is connected to a condensate collection tank.

[0007] Baffles are used to prevent fluid short-circuiting, increase fluid velocity, and force the fluid to flow through the tube bundle multiple times along a prescribed path, thereby increasing the degree of turbulence.

[0008] An air inlet duct is provided between the primary backwash filter and the deflector, and the fan is connected to the air inlet duct through the secondary backwash filter.

[0009] The upper portion of the precooling heat pipe is connected to the reheating heat pipe via a primary connecting pipe, and the lower portion of the reheating heat pipe is connected to the precooling heat pipe via a secondary connecting pipe.

[0010] The dehumidifying cold coil is provided with a heat-conducting condensation net, and the heat-conducting condensation net is provided with heat-conducting condensation mesh wires.

[0011] A reduced diameter pipe is provided between the dehumidification cold coil and the reheat heat pipe, and the reduced diameter pipe is smoothly connected to the inner wall of the U-shaped dehumidification energy-saving module.

[0012] After the air passes through the dehumidification cooling coil and the heat-conducting condensing mesh, the flow rate will increase when it passes through the reducing pipe. When the air flows from a larger diameter section to a smaller diameter section in the pipe, the flow rate will increase.

[0013] A V-shaped liquid accumulation bottom plate is provided below the inner wall of the U-shaped dehumidification and energy-saving module. The V-shaped liquid accumulation bottom plate is connected to a condensate collection tank, and the condensate collection tank is connected to a primary backwash filter through a condensate delivery pump.

[0014] The condensate delivery pump is connected to the secondary backwash filter through a pipeline, the U-shaped dehumidification and energy-saving module is connected to an air outlet pipeline, and the pre-cooling heat pipe is provided with a pre-cooling heat pipe coil.

[0015] The working principle of this utility model is:

[0016] The humid hot air enters the primary backwash filter through the fan for filtration, and then enters the U-shaped dehumidification and energy-saving module through the deflector. The humid hot air is pre-cooled through the pre-cooling heat pipe. The humid hot air transfers heat with the pre-cooling heat pipe, and the humid hot air releases heat. The medium in the pre-cooling heat pipe absorbs heat from the air, the humid air temperature decreases, and the relative humidity increases. The medium in the pre-cooling heat pipe absorbs heat and vaporizes and enters the reheating heat pipe end. The humid air cooled by the heat pipe enters the dehumidification cold coil, and the moisture in the air condenses after being cooled to saturation, thereby achieving the purpose of dehumidification; the air after passing through the dehumidification cold coil enters the reheating heat pipe again, transfers heat with the heat pipe, the low-temperature air absorbs heat, the temperature rises, the relative humidity decreases, the medium in the heat pipe releases heat, condenses from gas to liquid, and flows back along the pipe wall into the pre-cooling heat pipe, and this cycle repeats to achieve the purpose of energy-saving dehumidification; the condensate is collected into the condensate collection tank through the V-shaped liquid accumulation bottom plate, and then pumped into the first-level backwashing filter by the condensate delivery pump for backwashing. When the first-level backwashing filter is backwashed, the second-level backwashing filter starts to work.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model adopts the high-efficiency heat pipe dehumidification and energy-saving device for air conditioning in pharmaceutical workshops. Through the setting of the first-level backwash filter and the second-level backwash filter, the air entering the U-shaped dehumidification and energy-saving module is cleaned, and the condensed water in the condensate collection tank is used to backwash it, thereby avoiding the problem of particulate impurities entering the device with the air flow; through the setting of the pre-cooling heat pipe coil and the heat-conducting condensation net, the air resistance is reduced while minimizing the influence on the heat exchange efficiency. When used in conjunction with the reducing pipe, the air flow resistance is greatly reduced and the heat exchange efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS
