Abstract
The invention provides a surface air cooler of a low-volume fan coil unit. The surface air cooler comprises two rows of surface air cooler bend groups, surface air cooler closure plates, surface air cooler fins, a vent valve, a first collecting head and a second collecting head. Each row of surface air cooler bend groups consist of a plurality of U-shaped elbows and a plurality of surface air cooler bends communicated mutually through the U-shaped elbows, the surface air cooler bends penetrate through the surface air cooler closure plates and the surface air cooler fins respectively, the surface air cooler fins are arranged between the surface air cooler closure plates, two copper pipes are arranged on each of the first collecting head and the second collecting head, the two copper pipes on the first collecting head are connected with inlets of the surface air cooler bend groups hermetically, the two copper pipes on the second collecting head are connected with outlets of the surface air cooler bend groups hermetically, and the vent valve is arranged on the second collecting head. The surface air cooler has the advantages that as for the low-volume fan coil unit, the surface air cooler is capable of better guaranteeing water system smoothness and guaranteeing optimal heat exchange effect.
Description
Technical field
The invention belongs to refrigeration air-conditioner end technology field, especially relate to a kind of low air quantity fan coil units surface cooler.
Background technology
Along with social economy constantly develops, people are more and more higher to living space environmental requirement, all kinds of air-conditioning all enters the place of ordinary people family or various commercial use, the serviceability of user to machine group end is more and more higher, comprises running refrigerating (heat) ability, the unit eer etc. of end.If the heat transfer effect of surface cooler can be made to reach best, be just beneficial to the duty that machine group end reaches best.Due under heat exchange area and the approximately equalised situation of the temperature difference, total heat exchange amount and the coefficient of heat transfer are directly proportional, the coefficient of heat transfer increases, total heat exchange amount will increase, and then ensure that heat transfer effect reaches best, so require fan coil units on the low side for air quantity, how to ensure that heat transfer effect reaches the best and just needs reasonably to select part flow arrangement.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of low air quantity fan coil units surface cooler, is especially applicable to making fan coil units (200-400CFM) heat transfer effect reach best.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of low air quantity fan coil units surface cooler, comprise surface cooler bend pipe group, surface cooler shrouding, surface cooler fin, air bleeding valve, first collecting head, second collecting head, described surface cooler bend pipe component is two rows, often arrange and form by some U-shaped elbows and some surface cooler bend pipes, described some surface cooler bend pipes are connected by described some U-shaped elbows, described surface cooler bend pipe is each passed through described surface cooler shrouding and described surface cooler fin, described surface cooler fin is arranged between described surface cooler shrouding, described first collecting head, second collecting head is equipped with two copper pipes, two copper pipes on described first collecting head are connected with the inlet seal of described surface cooler bend pipe group, two copper pipes on described second collecting head are connected with the exit seal of described surface cooler bend pipe group, described air bleeding valve is arranged on described second collecting head.
Further, described low air quantity fan coil units air quantity is 200CFM-400CFM.
The advantage that the present invention has and good effect are: owing to adopting technique scheme, for low air quantity (200-400CFM) fan coil units, surface cooler adopts two pipes system, because surface cooler entire length is partially short, and total quantity of circulating water is certain, when selected hydraulic pressure, in unit are, to enter the water velocity entered than three pipes bigger than normal for two pipes, can better ensure that water system is smooth, ensure that heat transfer effect reaches best.

Detailed description of the invention
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Fig. 5, the invention provides a kind of low air quantity fan coil units surface cooler, this surface cooler fan coil units air quantity is 200CFM-400CFM, comprise surface cooler bend pipe group, surface cooler shrouding 2, surface cooler fin 3, air bleeding valve 5, first collecting head 7, second collecting head 6, surface cooler bend pipe component is two rows, often arrange and form by some U-shaped elbows 4 and some surface cooler bend pipes 1, surface cooler bend pipe 1 is connected by U-shaped elbow 4, surface cooler bend pipe 1 is each passed through surface cooler shrouding 2 and surface cooler fin 3, surface cooler fin 3 is arranged between two blocks of surface cooler shroudings 2, U-shaped elbow 4 is tightly connected with surface cooler bend pipe 1, first collecting head 7, second collecting head 6 is equipped with two copper pipes, two copper pipes on first collecting head 7 are connected with the inlet seal of surface cooler bend pipe group, two copper pipes on second collecting head 6 are connected with the exit seal of surface cooler bend pipe group, and air bleeding valve 5 is arranged on the second collecting head 6.
The course of work of this example: chilled water is entered by the first collecting head 7 and divides two-way to enter surface cooler bend pipe 1, and along with surface cooler bend pipe 1 is through surface cooler shrouding 2, afterwards again through surface cooler fin 3, inside surface cooler bend pipe 1, the chilled water of flowing is the Air flow flowing through surface cooler fin 3, and the cold air after cooling is delivered to field of employment cooling by blower fan; Final chilled water flows to the second collecting head 6 with absorbed heat, is finally brought back refrigeration unit, is sent back to the air of surface cooler heat absorption, cool stream warp again, constantly circulates after releasing heat, cooling.In this course, due under heat exchange area and the approximately equalised situation of the temperature difference, total heat exchange amount and the coefficient of heat transfer are directly proportional, again because the first collecting head 7, second collecting head 6 is provided with two copper pipes, hydraulic pressure certain at total quantity of circulating water is certain, in unit are, in copper pipe, water velocity strengthens, the coefficient of heat transfer is increased, total heat exchange amount increases, and then ensures that heat transfer effect reaches best, and Energy Efficiency Ratio strengthens.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
