Copper pipes in the surface air cooler are arranged into two rows and nine arrays, the whole copper pipes can be evenly divided into three water paths, the three water paths can satisfy the water resisting requirement and also strengthen the water-side heat transmission, and the copper pipes are in a 'Z'-shape trend, which can strengthen the heat transmitting effect of the surface air cooler.
Description
Technical field:
The utility model relates to the central air-conditioning end-equipment, the big enthalpy difference fan coil units of specifically a kind of two combs.
Background technology:
At present, known two comb fan coil units, the version of its surface cooler is 2 rows, 8 row, for reaching the heat exchange amount identical with three comb fan coil units, the mentalities of designing that adopt big air quantity, little enthalpy difference more, take measures in the aspects such as optimal design of less augmentation of heat transfer at surface cooler, wind system, thus the unit dehumidifying effect less, be not suitable for high humidity environment, the scope of application is little; Be the heat exchange area that guarantees surface cooler simultaneously, the height dimensions of 2 rows, 8 row fan coil units by the columns decision of surface cooler, can only increase size at length direction, thereby the cost of complete machine is higher, length dimension increases, the installing space of requirement is excessive.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of big enthalpy difference fan coil units of two combs of new construction, optimal design by set structure, strengthened the heat transfer of surface cooler, the height dimension that guarantees unit does not increase and lengthwise dimension shortens greatly, has not only increased substantially the cost performance of unit but also saved installing space.
The utility model technical solution problem adopts following technical scheme:
The big enthalpy difference fan coil units of two combs, comprise centrifugal blower, surface cooler, air inlet, air outlet, the air channel, water pond, motor, housing are rectangular-shaped, be provided with air inlet, air outlet, surface cooler and centrifugal blower are installed on the housing, and surface cooler is provided with total water inlet and total delivery port in whole heat exchange water route, and the below of surface cooler also is provided with water pond, the water pond bottom connects drainpipe, lengthwise dimension shortens greatly for the height dimension that guarantees unit does not increase, and has not only increased substantially the cost performance of unit but also saved installing space, and surface cooler of the present utility model adopts 2 rows, 9 row formula structures, surface cooler tilts to place in unit, so that height dimension is identical with 2 rows, 8 row.
Be the heat exchange of fortified water side, copper pipe in the utility model surface cooler is provided with by 2 rows, 9 row, whole copper pipe is divided into three water routes from top to bottom, form " Z " font trend by the elbow series connection between the copper pipe in each water route, each water route is respectively equipped with a water inlet and a delivery port, and three water inlet parallel connections in three water routes, three delivery port parallel connections form total water inlet and total delivery port of whole surface cooler respectively.
Be to strengthen the heat exchange of wind side, wind system of the present utility model is optimized design, has both improved the heat exchange of surface cooler, satisfies the requirements such as noise, windage, wasted work of complete machine again.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the surface cooler of the utility model fan coil units adopts 2 rows, 9 row formula structures, surface cooler tilts to place in unit, so that height dimension is identical with 2 rows, 8 row, the height dimension that guarantees unit does not increase and lengthwise dimension shortens greatly, not only reduces product cost significantly but also save installing space.
2, by the optimal design of set structure, strengthened the heat transfer of surface cooler, reach or, improved the cost performance of unit near the performance of the big enthalpy difference of three combs, overcome the not enough problem of dehumidifying effect that common two comb surface cooler fan coils exist.
3, copper pipe is provided with by 2 rows, 9 row in the surface cooler, and whole copper pipe can be divided into 3 water routes, and the copper pipe of present 2 rows, 8 tabulation coolers can only be divided into 2,4 or 8 water routes, and in a certain flow interval, the water resistance requirement both can have been satisfied in 3 water routes, but the fortified water side is conducted heat again; And copper pipe becomes " Z " font trend can strengthen the heat-transfer effect of surface cooler.
