Abstract
The utility model discloses a computer laboratory air-conditioning condenser, which comprises a power supply, a fan arranged on a computer shell, and a control device connected with the fan; the control device comprises a PCB board, a pressure sensor arranged on a refrigerating pipe; the fan and the pressure sensor are respectively connected with the PBC board. The utility model saves energy, reduces the cost of the device, is relatively low in the noise, and is good in the cooling effect.
Description
Technical field
The utility model relates to a kind of air-conditioning condenser, relates in particular to a kind of air conditioner in machine room condenser.
Background technology
Traditional air conditioner in machine room condenser is to adopt the 220V power voltage supply, mainly is made up of blower fan and control section.Wherein control section comprises temperature sensor, lightning protection plate, transformer, controller, and controller uses the P66 controller of JOHNSON company more.The shortcoming of this condenser is, the P66 controller architecture complexity of JOHNSON company, price is higher, has brought higher cost to the user, and, because control section is sealed in the environment of sealing, producing heat can't shed, and usually Yin Gaowen can't operate as normal to cause control section, in addition, the power of blower fan is less, and noise is bigger.
The utility model content
The technical problems to be solved in the utility model provides and a kind ofly saves that the energy, control device cost are lower, good heat dissipation effect, the smaller air-conditioning condenser of noise.
The utility model solves above-mentioned technical problem by the following technical programs: a kind of air conditioner in machine room condenser, comprise power supply, the blower fan on the casing, the control device that is connected with blower fan are installed, described control device comprises pcb board, is arranged on the pressure sensor on the refrigerator pipes, and blower fan, pressure sensor are connected with pcb board respectively.
Power input is connected with pcb board by breaker.
Pcb board connects blower fan by contactor.
Described control device is arranged in the control box on the casing, and seal cover seals control box by sealing strip, and the casing of pcb board correspondence is provided with heat sink, and described heat sink and pcb board are fitted.
Blower fan also is connected with temp control switch, the switching of temp control switch control contactor.
Described blower fan, pressure sensor, contactor, temp control switch are provided with two respectively, and pcb board connects two blower fans by two contactors respectively.
Pressure sensor of the present utility model is installed on the refrigerator pipes; when the refrigerator pipes internal pressure changes; pressure sensor becomes the signal of telecommunication with pressure signal and feeds back to pcb board; the effect of pcb board is the input voltage with 380 volts of external power sources; change into controlled output voltage; the rotating speed of control blower fan; thereby reach the purpose of control heat dissipation capacity; saved the energy, and reduced the noise of blower fan work, the effect of contactor is the protection blower fan; when environment temperature is too high; temp control switch is closed automatically, the contactor outage, and blower fan quits work.Be fixed with heat sink on the casing of pcb board correspondence, heat sink and pcb board are fitted, and the heat of pcb board generation is led on the casing by heat sink like this, reaches the purpose that pcb board fully dispels the heat by casing, casing good heat dissipation effect, radiating efficiency height.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is an embodiment control device structural representation;
Fig. 3 is the utility model control device circuit diagram.
