Accompanying drawing explanation
Fig. 1 is that the utility model uses magnetic valve bypass refrigerant to carry out the structural representation of the refrigerating plant of temperature control.
The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
Fig. 1 shows preferred embodiment of the present utility model, a kind of refrigerating plant that uses magnetic valve bypass refrigerant to carry out temperature control, comprise: refrigerating circuit, it is for returning via condenser 2, throttling arrangement 3 and evaporation 4 devices the circulating path that compressor 1 forms from compressor 1; Bypass circulation, it is for returning via evaporimeter 4 another circulating path that compressor forms from compressor 1; Refrigerant, it circulates in described refrigerating circuit and described bypass circulation, and refrigerant is specifically as follows R134a cold-producing medium; Bypass solenoid valve 5, it is arranged in bypass circulation to control the break-make of described bypass circulation; Tank for coolant 8, is loaded with cooling fluid in its casing, and evaporimeter 4 is positioned in the casing of described tank for coolant 8; Temperature controller 6, itself and bypass solenoid valve 5 are electrically connected, and temperature controller 6 obtains the temperature signal of cooling fluid and the wherein a kind of state in open mode and closed condition according to bypass solenoid valve described in temperature signal control.
In refrigerating circuit, the gaseous state that refrigerant is compressed into HTHP by compressor 1 transfers in condenser 2, the liquid condition that the refrigerant of the gaseous state of HTHP is cooled to high pressure low temperature by condenser 2 transfers in throttling arrangement 3, the gas-liquid two-phase state transfer that the refrigerant of the liquid condition of high pressure low temperature is compressed into low-pressure low-temperature by throttling arrangement 3 is to evaporimeter 4, and evaporimeter 4 becomes gaseous state to transfer in compressor 1 refrigerant evaporation of the gas-liquid two-phase state of low-temp low-pressure.
In bypass circulation, the refrigerant that compressor 1 is compressed into refrigerant in gaseous state and the refrigerating circuit of HTHP crosses, and heats to the refrigerant that is about to transfer in evaporimeter 4.
Temperature controller 6 obtains the temperature signal of cooling fluid, and in the time detecting that the temperature of cooling fluid drops to certain temperature value, temperature controller 6 is controlled bypass solenoid valve 5 in open mode, is communicated with bypass circulation, plays the effect heating up to cooling fluid; In the time detecting that certain temperature value is arrived in the temperature rise of cooling fluid, temperature controller 6 is controlled bypass solenoid valve 5 in closed condition, cuts off bypass circulation, and coolant temperature no longer raises.
For example, cooling fluid initial temperature in tank for coolant 8 is 30 degree, refrigerating plant operation makes coolant temperature be reduced to 9 while spending, temperature controller 6 is controlled bypass solenoid valve 5 in open mode, and when coolant temperature rises to 10 while spending, temperature controller 6 is controlled bypass solenoid valve 5 in closed condition, now, coolant temperature is controlled between 9 degree and 10 degree, and compressor 1 just can keep duty, avoids compressor 1 frequently stop and restarting.
Temperature controller 6 can be the model temperature controller that is T-503, and the utility model is not made any improvement to temperature controller 6.
