Can know that by technique scheme the utility model passes through the temperature in the instant perception water tank of temperature sensor in the water tank, and feeds back to controller; Water tank temperature and setting value are compared, and controller is through the output cold of the time cycle control appliance of control electric heater unit and magnetic valve break-make, Fast Heating when temperature is lower than setting value; Fast-refrigerating when temperature is higher than setting value; Constantly conversion makes equipment be in temperature constant state all the time, and control accuracy is high.
Description of drawings
Fig. 1 is the system architecture sketch map of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
Water circulation cooling device as shown in Figure 1; Comprise compressor 10, the output of compressor 10 is provided with first, second branch road, and first, second branch road of compressor output end links to each other with the input of condenser 20 and the input of magnetic valve 30 respectively; The output of condenser 20 links to each other with the input of capillary 40 or expansion valve; The output of capillary 40 or expansion valve links to each other with the input of evaporimeter 50, and the output of evaporimeter 50 is provided with first, second branch road, and first, second branch road of evaporimeter 50 outputs links to each other with the input of compressor 10 and the output of magnetic valve 30 respectively; The water side output of evaporimeter 50 links to each other with the input of water tank 60; The output of water tank 60 links to each other with the input of water pump 70, and the output of water pump 70 links to each other with the input of load heater 80, and the output of load heater 80 links to each other with the water side input of evaporimeter 50; Wherein, Be provided with electric heating equipment 61 and temperature sensor in the water tank 60, magnetic valve 30, electric heating equipment 61 all link to each other with controller with temperature sensor, and magnetic valve 30 is a normally closed solenoid valve.
Equipment is when work; At first set a temperature value; This temperature value generally approaches the required normal temperature value of equipment; Temperature sensors in the water tank 60 feed back to controller in real time with water temperature, when the real time temperature value in the water tank during near setting value, and the output cold of the make-and-break time cycle control appliance through control electric heater unit 61 and magnetic valve 30.The control mode of the utility model adopts the cold and hot two-way control of PID.
The concrete course of work is following:
It is as shown in Figure 1 that (what solid arrow was represented among Fig. 1 is the recurrent state of cold-producing medium, and what dotted arrow was represented is the recurrent state of cold water.) when normality, magnetic valve 30 is in closure state, at this moment compressor 10 is with the cold-producing medium compression of low-temp low-pressure; Discharge the gas of HTHP; Gas arrives condenser 20 through first branch road of compressor output end, and the refrigerant gas with HTHP in condenser 20 passes through blower fan to the outside heat release, simultaneously refrigerant gas is condensed into highly pressurised liquid; Condensed highly pressurised liquid is again through getting into evaporimeter 50 after capillary 40 step-downs; Cold-producing medium absorbs the heat of the water that is cooled in evaporimeter 50, be evaporated to gaseous state by liquid state, is got back to the input of compressor 10 again by first branch road of evaporimeter output.Simultaneously, the backwater of load heater 80 in evaporimeter 50 with the cold-producing medium heat exchange, become chilled water and get into water tank 60, output to load heater 80 through water pump 70 again, thereby load cooled off.On overall; Be exactly that temperature sensor in the water tank 60 feeds back to controller with the temperature in the water tank immediately, water tank temperature and setting value are compared, again through the cold and hot two-way control mode of PID; Control the output cold of the time cycle control appliance of electric heater unit 61 and magnetic valve 30 break-makes; Promptly when the temperature of the temperature sensor perception in the water tank 60 was higher than setting value, at this moment controller provided signal, and electric heater unit 61 quits work; Magnetic valve 30 outages make the temperature in the water tank 60 reach setting value fast; If the temperature of the temperature sensor perception in the water tank 60 is lower than setting value; Controller provides signal; Electric heater unit 61 is started working, magnetic valve 30 energisings, and the high temperature and high pressure gas that at this moment comes out from compressor 10 is got back to compressor 10 again through magnetic valve 30; Be the of short duration refrigeration of cutting off cold-producing medium, make the temperature in the water tank 60 reach setting value fast.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the definite protection domain of the utility model claims.
