Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dehumidifiers, and particularly relates to a novel unpowered continuous water replenishment cooling water system and method for a dehumidifier. BACKGROUND

[0002] When a common water-cooled temperature-regulating dehumidifier is dehumidifying, a cooling water system is needed to take out condensation heat, and there are two conventional ways. The first way is that a cooling water tank is used as a buffer water tank, and after heat exchange, the water in the buffer water tank is directly discharged when the water reaches a preset temperature; this way consumes a large amount of water, but the volume of the buffer water tank can be appropriately reduced. The other way is that a cooling water tank is used as a heat exchange water tank, and as condensation heat is continuously discharged, the water temperature in the cooling water tank continuously rises, and when the water temperature rises to a water replacement temperature, the cooling water circulation system of the water-cooled condenser stops, the dehumidifier stops, and the cooling water tank starts to replace water; after the cooling water tank is replaced with water, the water temperature in the cooling water tank drops, the cooling water circulation system of the water-cooled condenser starts to operate, and the dehumidifier is started again, and this goes on and on; this way requires a large volume of the cooling water tank, occupies a large space, and the dehumidifier has an intermittent operation problem, and a second water pump is needed for rapid water discharge.

[0003] For example, the prior art CN113883628A discloses an air conditioning system, which belongs to the above-mentioned conventional cooling water replenishment way. SUMMARY

[0004] The purpose of the present application is to overcome the deficiencies in the prior art, and to provide a novel unpowered continuous water replenishment cooling water system and method for a dehumidifier, which not only reduces the volume of the cooling water tank, saves space and cost, but also realizes unpowered continuous water replenishment (without the need for a water replenishment pump or a water discharge pump), saves energy, and continuously replaces water stably, improves the operation stability of the dehumidifier (without interruption), and is particularly suitable for dehumidifying in a limited installation and operation condition environment such as a cave.

DETAILED DESCRIPTION

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] like Figure 1 As shown, a novel non-powered continuous water supply cooling water system for a dehumidifier includes a compressor 1, a water-cooled condenser 2, a finned evaporator 3, a finned condenser 4, a fan 5, a liquid receiver 6, a water pump 7, and a lower water tank 8. The first end of the compressor 1 is connected to the finned evaporator 3 via a pipeline, the second end of the compressor 1 is connected to the liquid receiver 6 via a pipeline, the other end of the liquid receiver 6 is connected to the water-cooled condenser 2 and the finned condenser 4 via pipelines, and the third end of the compressor 1 is connected to the water-cooled condenser 2 via a pipeline. A fan 5 is installed downstream of the finned condenser 4. The lower / bottom left side of the lower water tank 8 is connected to the water-cooled condenser 2 via a cooling water inlet pipe, and the upper / bottom left side of the lower water tank 8... The top left side is connected to the water-cooled condenser 2 via a cooling water outlet pipe. A water pump 7 and a control valve / regulating valve are installed on the cooling water inlet pipe. A drain pipe is installed on the lower / bottom right side of the lower water tank 8, and an electric valve 82 is installed on the drain pipe. The feature is that it also includes an upper water tank 9. The lower water tank 8 and the upper water tank 9 are separated into a lower water tank 8 and an upper water tank 9 by a partition 91. A water passage hole 92 is opened on the partition 91. A float valve 93 is installed in the upper water tank 9. The float valve 93 is connected to the water source through a water inlet pipe. A water level sensor 94 is installed in / on the upper water tank 9. A drain outlet 81 is installed on the lower / bottom right side of the lower water tank 8, and the drain outlet 81 is connected to the drain pipe.

[0019] Water in the upper water tank 9 enters the lower water tank 8 through the water inlet 92 under the action of gravity. The water inlet volume of the water inlet 92 on the partition 91 is basically the same as / the same as the water outlet volume of the drain 81, and / or the equivalent area of ​​the water inlet 92 is the same as the equivalent area of ​​the drain 81.

[0020] The working principle / control method of the new type of unpowered continuous water replenishment cooling water system of the dehumidifier of the present application is as follows: the condensation heat generated by the water-cooled condenser 2 of the dehumidifier enters the cooling water circulation system, and the dehumidifier continuously discharges condensation heat to the cooling water tank (lower water tank 8) of the cooling water system during operation. The absorbed condensation heat continuously raises the temperature of the lower water tank 8, and when the temperature rise reaches a certain preset temperature, the electric valve 82 opens to discharge the water in the lower water tank 8. At this time, the water in the upper water tank 9 enters the lower water tank 8 through the water passage hole 92 under the action of gravity. Since the water discharge capacity of the drain port 81 and the water inlet capacity of the water passage hole 92 are basically the same / same (and / or the equivalent area of the water passage hole 92 and the equivalent area of the drain port 81 are the same), the lower water tank 8 always maintains a full water state. When the temperature of the lower water tank 8 drops to the temperature of the upper water tank 9 or the water inlet temperature of the water passage hole 92, the electric valve 82 is closed, the water replacement of the lower water tank 8 is completed, and the water lacking in the upper water tank 9 is replenished in time through the float valve 93 and the water inlet pipe connected to the external water source to complete the automatic water replenishment of the upper water tank 9. During the water replacement process of the lower water tank 8, the dehumidifier operates stably to achieve continuous water replenishment of the cooling water system and the purpose of water replacement and cooling.

[0021] In this way, the purpose of water replacement and cooling can be achieved without external power, saving energy. The water discharge capacity of the drain port 81 of the lower water tank 8 and the water inlet capacity of the water passage hole 92 are the same, achieving continuous water replenishment of the cooling water system (without the need for a water replenishment pump or a water discharge pump), and the dehumidifier system operates stably (without interruption). Through the design of the combined cooling water tank, the volume of the water tank can be effectively reduced, and the space utilization rate can be improved, which is particularly suitable for dehumidification projects in underground vaults.

[0022] Further, the water passage hole 92 on the partition plate 91 is arranged on the left side of the partition plate 91, that is, the water passage hole 92 is arranged close to the end of the cooling water outlet pipe connected to the lower water tank 8. By arranging the water passage hole 92 on the left side of the partition plate 91, when the temperature of the lower water tank 8 rises to a certain preset temperature to start water replacement, the cooling water in the upper water tank 9 can preferentially cool the hot water entering the cooling water outlet pipe, thereby shortening the water replacement time of the lower water tank 8 and improving the water replacement and cooling efficiency.

[0023] The first water temperature sensor 83 is arranged on the left side of the lower end / bottom end of the lower water tank 8, and the first water temperature sensor 83 is arranged close to the inlet end of the cooling water inlet pipe.

[0024] Optionally, a first one-way valve is arranged on the water passage hole 92, and a second one-way valve is arranged on the drain port 81.

[0025] In another embodiment, a second water temperature sensor 84 is arranged on the cooling water inlet pipe and close to one end of the lower water tank 8, and a third water temperature sensor 85 is arranged on the cooling water outlet pipe and close to one end of the lower water tank 8; a correction parameter K is obtained through experiments and fitting calculation, K = f (T1, T2, Vt, V), wherein T1 is the temperature value of the second water temperature sensor, T2 is the temperature value of the third water temperature sensor, Vt is the rotation speed value of the water pump 7, and V is the volume of the lower water tank, and each variable takes a numerical value in the fitting calculation; when the temperature rise of the lower water tank 8 reaches a certain preset temperature, the measured correction parameter K is compared with a preset correction parameter Ks to determine whether the water replacement operation of the lower water tank 8 is immediately performed.

[0026] Further, when the measured correction parameter K = the preset measured correction parameter Ks, the electric valve 82 is opened, and the water replacement operation of the lower water tank 8 is immediately performed; when the measured correction parameter K < the preset correction parameter Ks, it is indicated that due to the setting position of the first water temperature sensor 83 and the water flowability in the lower water tank 8, the overall average water temperature does not reach the certain preset temperature, but the first water temperature sensor 83 meets the certain preset temperature condition, at this time, the rotation speed Vt of the water pump 7 is increased, and the water flow speed of the cooling water inlet pipe and the cooling water outlet pipe is accelerated, so that the utilization rate of the cooling water is improved, and the water resource is saved.

[0027] The application is a new type of unpowered continuous water replenishment cooling water system and method of a dehumidifier, which not only reduces the volume of the cooling water tank (the lower water tank 8 and the upper water tank 9) to save space and cost, but also realizes the unpowered continuous water replenishment mode (without a water replenishment pump or a water drainage pump) to save energy and continuously replace water to improve the operation stability of the dehumidifier (without interruption), and is particularly suitable for the working conditions of a cave and other environments that need to be dehumidified and have limited installation and operation conditions.

[0028] The above embodiments are illustrative of the application, but are not limiting of the application. It can be understood that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the application, and the protection scope of the application is defined by the appended claims and their equivalents.
