Embodiment 1

[0030] Such as figure 1 As shown, the present invention is used for the water film evaporation condensing device of central air-conditioning, comprises the condensing tube 1 that vertically places, and the upper end of condensing tube 1 is provided with intake pipe 2, and the bottom of condensing tube 1 is provided with drain pipe 3, and draining The outlet end of the pipe 3 is connected with a recovery box 4, and a sleeve 5 coaxial with the condensation cylinder 1 and at the same height as the condensation cylinder 1 is arranged outside the condensation cylinder 1. There is a gap between the condensation cylinder 1 and the sleeve 5, and the top of the sleeve 5 is set A plurality of through holes inserted into the water distribution pipe 6, the water distribution pipe 6 corresponds to the through hole one by one, all the water distribution pipes 6 inserted into the sleeve 5 are evenly distributed on the outside of the condenser tube 1, and there are many connected under the bot...

Embodiment 2

[0034] Based on Embodiment 1, the recovery tank 4 is located inside the water tank 8 , the bottom of the recovery tank 4 is detachably connected to the bottom of the water tank 8 , and the outlet end of the drain pipe 3 passes through the top of the water tank 8 and communicates with the recovery tank 4 .

[0035] The recovery tank is installed inside the water tank, and the condensed water in the water tank can condense the refrigerant in the recovery tank, which is not only suitable for refrigeration of the refrigerant but also can cool the refrigerant, and improves the condensation efficiency of the refrigerant.

Embodiment 3

[0037] Based on the above-mentioned embodiment, the upper ends of all the water distribution pipes 6 are connected and fixed on the tube sheet 10 placed horizontally, and the tube sheet 10 is located above the sleeve 5 . At least two vertically placed electric push rods 11 are connected above the tube sheet 10 , and there is a support column 12 for installing the electric push rods 11 below the electric push rods 11 .

[0038] The tube plate is used to centrally install all the water distribution pipes, which is convenient for the use of the water distribution pipes. The position of all the water distribution pipes can be changed by moving the tube plate, which improves the working efficiency of the whole device.

[0039]The electric push rod moves up and down, which can move the water distribution pipe up and down. After pouring water into the condensing cylinder, the electric push rod moves upward to take out the water distribution pipe, which provides enough space for the ai...

Abstract

The invention discloses a water film evaporation and condensation device and a condensation method for central air conditioners. The water film evaporation and condensation device for central air conditioners comprises a condensing cylinder, the upper end of the condensation cylinder is provided with an air intake pipe, and the lower part of the condensation cylinder is provided with a liquid discharge pipe The outlet end of the drain pipe is connected with a recovery box, a sleeve is arranged outside the condensation cylinder, a through hole for inserting a water distribution pipe is arranged on the top of the sleeve, a drain pipe is connected under the bottom of the sleeve, and a water tank is connected with the lower end of the drain pipe. The side wall of each drainage pipe is connected with an air guide pipe, and the air guide pipe is connected with a fan in one-to-one correspondence; the condensation method of the water film evaporation and condensation device for central air conditioning includes the following steps: inserting the water distribution pipe into the sleeve, and distributing the The water pipe evenly sprays water on the condensing cylinder to form a water film on the outer wall of the condensing cylinder; the high-temperature gaseous refrigerant enters the condensing cylinder, and the water film outside the condensing cylinder absorbs heat and turns into a liquid that flows into the recovery box; the fan flows to the inside of the sleeve Hair dryer. The present invention has high condensation efficiency.

Description

technical field [0001] The invention relates to a central air-conditioning condensing device and a condensing method, in particular to a water film evaporation condensing device and a condensing method for the central air-conditioning. Background technique [0002] With the development of the economy and the continuous progress of science and technology, industrial and civil large-scale central air-conditioning systems have been widely used. The central air-conditioning system is composed of one or more cold and heat source systems and multiple air-conditioning systems. This system is different from traditional refrigerant air-conditioning systems (such as single unit, VRV) to centrally process air to meet comfort requirements. It uses liquid vaporization The principle of refrigeration provides the required cooling capacity for the air conditioning system to offset the cooling load of the indoor environment. [0003] During the working process of the central air conditioner...
