Description
Technical field
The utility model relates to the off-premises station that a kind of variable air rate is regulated the Teat pump boiler of evaporation load.
Background technology
The ambient temperature range that with the air is the Teat pump boiler work of thermal source requires non-constant width, generally spends more than 40 degree above freezing from subzero 10, and along with the variation of environment temperature, the evaporability of evaporimeter is respective change also, and environment temperature is high more, and evaporability is strong more.If the evaporability of evaporimeter is not controlled, too high evaporation is increased compressor load, and compressor electric motor is transshipped, and influences the normal operation of unit, may burn compressor when serious.
Summary of the invention
At the problem that prior art exists, the purpose of this utility model is to provide a kind of variable air rate to regulate the off-premises station of the Teat pump boiler of evaporation load, and this outdoor function makes Teat pump boiler normal, safe operation under various environment temperatures.
For achieving the above object, the technical scheme taked of the utility model is:
A kind of variable air rate is regulated the off-premises station of the Teat pump boiler of evaporation load, comprise compressor, gas-liquid separator, evaporation coil, axial flow blower, cross valve, device for drying and filtering, throttling arrangement and fluid delivery tube, described off-premises station also comprises temperature sensor, temperature transmitter and frequency converter; Temperature sensor is fixed on the compressor air suction pipeline, is connected through electric wire between temperature sensor and the temperature transmitter, is connected through electric wire between temperature transmitter and the frequency converter; Temperature sensor is passed to the temperature signal of compressor suction duct temperature transmitter and is changed the signal of telecommunication into, passes to frequency converter again, and frequency converter is according to the signal of telecommunication Control Shaft flow fan rotating speed of motor of carrying, with the evaporability of control evaporimeter.
Further, described throttling arrangement can be a capillary, also can be heating power expansion valve or electric expansion valve.
Further, described temperature sensor is installed on the described compressor suction duct or on the described gas-liquid separator or described cross valve to the pipe of compressor chamber or on the pipe between cross valve and the gas-liquid separator.
Further, described temperature sensor, temperature transmitter and frequency converter are loaded in the off-premises station or are loaded in the external electric appliance box.
The utility model is determined the initial set value of corresponding temperature transmitter output current value as the blower fan speed change according to the high evaporation temperature in the normal range of operation of compressor.When evaporability increases, evaporating temperature is raise, after temperature transmitter receives the signal of evaporating temperature rising by temperature sensor, it is big that output current becomes, when being elevated to the setting value of blower fan frequency with the corresponding electric current of evaporating temperature, the output frequency of frequency converter reduces, and the operating frequency of blower fan reduces, and evaporability descends thereupon.The utility model variable air rate is regulated the off-premises station of the Teat pump boiler of evaporation load, can regulate evaporating temperature or pressure automatically when environment temperature is higher, make unit can be normally, safe operation.
Description of drawings
Fig. 1 is the off-premises station schematic diagram that variable air rate is regulated the Teat pump boiler of evaporation load.
The specific embodiment
The off-premises station that variable air rate is regulated the Teat pump boiler of evaporation load comprises compressor 8, gas-liquid separator 9, evaporation coil 2, axial flow blower 1, cross valve 7, device for drying and filtering 14, throttling arrangement 15 and fluid delivery tube composition, referring to Fig. 1; Be provided with temperature sensor 6, temperature transmitter 5 and frequency converter 4 in the off-premises station of the Teat pump boiler of variable air rate adjusting evaporation load; Temperature sensor 6 is fixed on the pipe 11 between gas-liquid separator and cross valve, is connected through electric wire between temperature sensor 6 and the temperature transmitter 5, also is connected through electric wire between temperature transmitter 5 and the frequency converter 4; Temperature sensor 6 is passed to the temperature signal of pipe 11 temperature transmitter 5 and is changed the signal of telecommunication into, passes to frequency converter 4 again, and frequency converter 4 is according to the motor speed of this signal of telecommunication Control Shaft flow fan 1, thus the evaporability of change evaporation coil 2.In the present embodiment, the throttling arrangement of the off-premises station of the Teat pump boiler of variable air rate adjusting evaporation load is a capillary 15.Temperature sensor 6 is installed on the pipe 11 between gas-liquid separator and cross valve; Temperature sensor 6, temperature transmitter 5 and frequency converter 4 are loaded in the shell 3 of off-premises station.
Refrigerant liquid enters off-premises station by pipe 13, behind device for drying and filtering 14, capillary 15, in evaporation coil 2, flash to gas, get back to compressor through cross valve 7, gas-liquid separator 9 by air intake duct 10 then, become the gas of HTHP after the compressed machine compression, be discharged to Teat pump boiler through pipe 12, cross valve 7, pipe 16 then.
When environment temperature was not too high, evaporating temperature maintained in normal and the scope that compressor allows.When environment temperature raises; evaporating temperature can increase; temperature sensor 6 is passed to temperature transmitter 5 with signal; pass to frequency converter 4 after being transformed into the signal of telecommunication; adjust output frequency by frequency converter 4 rotation speed of fan is reduced, evaporating temperature can decrease then, like this; evaporating temperature is controlled in the scope of a permission all the time, guarantees unit safety operation.
Present embodiment adopts the compressor of ZR6 1KC-TFD model, and the model of frequency converter is ATU31H018M2A, and the model of temperature transmitter is NPPD11, and the specification of gas-liquid separator adopts 5L's.
