Description

The household air conditioning heat exchange coil

The utility model relates to a kind of novel idle call heat exchange coil, it belongs to the improvement to air-conditioning, cooling heat transmission equipment, is mainly used in the residential central air-system.It mainly is made of pipe (1), inlet short tube (2), influent header (3), outlet header (4), " U " shape pipe (5), capillary (6), fin (7), outlet short tube assemblies such as (8).

Existing heat exchange coil, in the same coil pipe, the connection form between the pipe has only a kind of, and many pipes among the row are to be serially connected exactly, and its equivalent result is to make pipe elongated, is relation in parallel between row and row, and its equivalent result is to have made the pipe chap.And same coil pipe can only lead to a kind of heat transfer medium, and heat transfer medium number of turns in pipe is many, long flow path, resistance big (number is 97122649.0 as Chinese patent application).The purpose of this utility model is exactly the deficiency that will overcome existing heat exchange coil, and a kind of novel heat exchange coil is provided, and it has two groups of coil pipes, the connection form difference in every group of coil pipe between the pipe, and the heat transfer medium that passes through in every group of coil pipe is also different.

The utility model is the used heat exchange coil of a kind of household air conditioning, comprise the fin (7) that is arranged parallel to each other with a determining deviation, air passes through between sheet along direction of ventilation, and the pipe (1) that passes above-mentioned fin (7), heat transfer medium flows through therein, it is characterized in that, the pipe (1) that passes fin (7) is divided into two groups along direction of ventilation, pipe group A and pipe group B, connecting mode difference among pipe group A and the pipe group B between the pipe (1), air skims over pipe group B earlier, skims over pipe group A then, and what flow through among pipe group A and the pipe group B is two kinds of different heat transfer mediums.

In the utility model: the heat transfer medium that flows through among the pipe group A is a water, and the heat transfer medium that flows through among the pipe group B is the cold-producing medium of non-water.Pipe (1) among the pipe group A is divided into two groups along direction of ventilation, pipe group A1 and pipe group A2, the end that pipe group A1 is adjacent with pipe group A2 is linked together with " U " shape pipe (5), pipe group A1 and pipe group A2 are formed to be connected in series, the other end of pipe group A1 is connected in parallel with inlet header (3), the other end of pipe group A2 is connected in parallel with outlet header (4), import short tube (2) is arranged on the inlet header (3), heat transfer medium is from wherein flowing into, outlet short tube (8) is arranged on the outlet header (4), and heat transfer medium is from wherein flowing out.Air skims over pipe group A2 earlier, skims over pipe group A1 then.The pipe (1) that is arranged above and below in the same row among the pipe group B is connected in series with " U " shape pipe (5), is relation in parallel between row and row, and heat transfer medium advances, brings out down from each row's upper end.The inlet access tube of each pipe in row the top is one section diameter capillary (6) littler than pipe (1) diameter among the pipe group B.

The utility model is mainly used in the residential central air-system, and the heat transfer medium collateral resistance of pipe group A is little, can directly connect central heating pipe network, domestic heating stove, central cooling and freeze waterpipe and underground water pipeline; Pipe group B can directly connect compressor refrigeration system.The utility model can lead to multiple heating agent and refrigerant, is used for fan coil system, can be easy to realize household metering, program control heating, automatic control, energy savings.

Description of drawings: Fig. 1 is the front view of the utility model embodiment, and Fig. 2 is a left view, and Fig. 3 is a right view, and Fig. 4 is a rearview.

The drawing of accompanying drawing is described as follows: 1-pipe 2-import short tube 3-inlet header 4-outlet header 5-" U " shape pipe 6-capillary 7-fin 8-outlet short tube hollow arrow-air draught direction A-pipe group A B-pipe group BA1-pipe group A1 A2-pipe group A2

Narrate an embodiment of the present utility model below in conjunction with accompanying drawing.

Fin (7) is a rectangle, equidistant being arranged in parallel between sheet and the sheet, and pipe (1) has 6 rows, and every row has 12, and the arrangement mode of pipe is wrong row.

Two array of pipes of windward side are pipe group B, pipe among every row is cascaded with " U " shape pipe, topmost one is inlet, bottom one is outlet, the porch is the capillary (6) that one section section dwindles suddenly, cold-producing medium enters through capillary (6), and flow out from outlet step-down, cooling, heat absorption evaporation back.

Four array of pipes of leeward side are pipe group A, and wherein, two rows of weather side are pipe group A2, and two rows of downwind side are pipe group A1.Connecting mode between the tube and tube of pipe group A rear end is that the corresponding pipe in position links together with " U " shape pipe among pipe group A1 and the pipe group A2.Connecting mode between the tube and tube of pipe group A front end is, every array of pipes all uses a thicker pipe that 12 pipes are connected together, the upper end of two extra heavy pipe connects together among the pipe group A1, form inlet header (3), and pick out an import short tube (2), the lower end of two extra heavy pipe connects together among the pipe group A2, forms outlet header (4), and picks out an outlet short tube (8).The flow process of water in pipe group A be, enters from the inlet short tube, all assigns in every pipe of pipe group A1 by inlet header (3), enters in every pipe of pipe group A2 through " U " shape pipe of rear end, after outlet header (4) is pooled to the outlet short tube of lower end flows out.
