Description
Technical field
The utility model relates to the end equipment of central air-conditioning, relates in particular to a kind of fan coil.
Background technology
Central air-conditioning is the indispensable apparatus of air conditioning in the meeting of China production society.Fan coil is the vitals that carries out heat exchange in the central air-conditioning.Unit performance and efficient that the efficient height of fan coil and behavior in service directly have influence on central air-conditioning.Noise ratio was bigger when the fan coil of prior art existed running, and the gas flow resistance is big, the cold that under standard cooling operating mode, is reached, and the output that needs is big, the more high deficiency of energy resource consumption.The big temperature difference unit that uses has two kinds at present: a kind of is the inflow temperature that has changed chilled water, and generally about 5 ℃, this is even lower the temperature of chilled water with regard to needing handpiece Water Chilling Units, causes also just corresponding the increasing of energy consumption of handpiece Water Chilling Units.Another kind is chilled water turnover 7 ℃/14 ℃ of temperature parameters (temperature difference is 7 ℃), and is this only to save the sub-fraction output.
Summary of the invention
The purpose of this utility model is: overcome the deficiencies in the prior art, thereby provide a kind of running steady, air drag is little, the big temperature difference fan coil of high-performance that the energy resource consumption when standard cooling operating mode is issued to certain cold is low.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the big temperature difference fan coil of a kind of high-performance, has body, blower fan is housed in the body, the motor that links to each other with blower fan, heat exchanger is characterized in that: described blower fan is big fan impeller, and motor is a buncher, blower fan and motor are connected on the blower fan supporting plate of body jointly, and this connected mode can make blower motor more reliable and more stable when operation.Described heat exchanger is that coil pipe is finned, is provided with two, is respectively refrigeration heat converter and heats heat exchanger, is arranged in parallel on the left side plate of body.The blower fan supporting plate is connected with left side plate to be connected with air-intaking box has more just formed complete unit, and connected mode makes that the unit vibrations are littler longitudinally, and noise also can reduce accordingly.Compare with prior art, structure of the present utility model can make the gas flow resistance reduce, and overcomes the gap and reveals, and avoids air and unit heat transfer losses.
Described body is provided with the return air plenum chamber, is provided with screen pack in the case.Screen pack be connected return air plenum chamber chute up and down and link to each other, chute can change width according to the thickness of screen pack.
As preferably, be provided with the deep bead that is used to adjust the heat exchanger height and plays sealing function below the described heat exchanger.
As preferably, described blower fan and motor shaft adopt socket connection, and between centers is located with tapered thread.
As preferably, heat heat exchanger and adopt 5 row's water-in and water-out coil pipes.
Therefore, the beneficial effects of the utility model are:
1. can realize the energy-conservation effect of the big temperature difference of high-performance.Conventional unit (27 ℃ of air intake dry-bulb temperatures, 19.5 ℃ of wet-bulb temperature) under standard cooling operating mode, the cold that chilled water turnover temperature parameter 7 ℃/12 ℃ (temperature difference is 5 ℃) is reached needs certain output; Heat exchanger of the present utility model can realize that chilled water turnover temperature parameter 7 ℃/17 ℃ (temperature difference is 10 ℃) reaches the identical cold in front or higher, the output of this moment is but far below the output of the 5 ℃ of temperature difference in front, maximum can reduce by 50%, thereby reach saving confession backwater tubing and installing space, installation cost, the flow power of water circulating pump reduces, power consumption also just reduces, and the loss of energy in system simultaneously also can reduce accordingly.
The utility model longitudinally connected mode make unit vibrations littler, noise also can reduce accordingly.Compare with prior art, structure of the present utility model can make the gas flow resistance reduce, and overcomes the gap and reveals, and avoids air and unit heat transfer losses.
3. simultaneously because motor adopts multispeed electric machine, can effectively satisfy the adjusting of user to the air quantity of different periods, cold, heat, also can adapt to the installation under the different resistance pipelines.
4. motor and blower fan axle adopt tapered threaded post closely to connect, and are fixed on jointly on the blower fan supporting plate, and this connected mode can make blower motor more reliable and more stable when operation.
