In one embodiment, a kind of thermostatic type cooling-water machine 100, including compressor 10, condenser 20, choke valve 30 and condensation Vaporizer 40, its are also included in order to house the cold tanks 50 of cold water, first switch part 60, in order to detecting cold water storage cistern Control first switch part 60 to close and detecting the temperature of cold water storage cistern higher than high temperature threshold value when temperature is less than low temperature threshold When open temperature control part 57, in order to first switch part 60 open after close and first switch part 60 close after open Second switch part 70, the outfan of compressor 10 connects the input and second switch part 70 of condenser 20 simultaneously, the Two switch block 70 connects vaporizer, and the outfan of condenser 20 connects the input of the first switch part 60, and first opens The outfan of GUAN spot part 60 connects the input of choke valve 30, and the outfan of choke valve 30 connects the input of condenser/evaporator 40 End, the outfan of condenser/evaporator 40 connect the input of compressor 10, and condenser/evaporator 40 is installed on inside cold tanks 50.

Above-mentioned, a kind of thermostatic type cooling-water machine 100, compressor 10 can export the working media of High Temperature High Pressure, and the work is situated between Matter becomes the working media of normal temperature high voltage after the cooling of condensed device 20, and then the working media of normal temperature high voltage draws from condenser 20 It flow in choke valve 30, choke valve 30 connects condenser/evaporator 40, the working media of normal temperature high voltage is drained to cold from choke valve 30 Reduced pressure after solidifying vaporizer 40, working media gasification heat absorption form the working media of high-temperature low-pressure, that is to say, now condensation is steamed Send out the effect that device 40 primarily serves vaporizer.The working media of high-temperature low-pressure returns compressor 10 by 40 drain of condenser/evaporator again and enters Row pressurization, is then drained to condenser 20 again, and therefore, working media is steamed in compressor 10, condenser 20, choke valve 30, condensation Circulate in the chilled water system of the connection formation for sending out device 40.

In the present embodiment, also include that condenser/evaporator 40 is placed in cold tanks by cold tanks 50, cold tanks 50 In 50, i.e., condenser/evaporator 40 is installed on inside cold tanks 50, and the working media in condenser/evaporator 40 can be with cold water water Water in case 50 carries out heat exchange.That is, when condenser/evaporator 40 plays a part of vaporizer, the work in condenser/evaporator 40 Make the heat of water in Absorption of Medium cold tanks 50, so as to the temperature of the water in cold tanks 50 reduces；When condenser/evaporator 40 When playing a part of condenser 20, the working media in condenser/evaporator 40 transfers heat to the water in cold tanks 50, from And the temperature of the water in cold tanks 50 is raised.

Need it is further noted that in the present embodiment, also include first switch part 60, second switch part 70, Temperature control part 57.Temperature control part 57 is installed in cold tanks 50 temperature value of water in measurement cold tanks 50, and condenser 20 is by the One switch block 60 connects choke valve 30, and compressor 10 connects condenser/evaporator 40 by second switch part 70.Second switch The working condition of part 70 with first switch part 60 conversely, that is to say, when first switch part 60 is opened, second switch portion Part 70 is closed；When first switch part 60 is closed, second switch part 70 is opened.

When compressor 10 starts, first switch part 60 is opened, and second switch is closed, i.e., working media is in condensation evaporation The heat of the water in cold tanks 50 is absorbed in device 40, and condenser/evaporator 40 plays a part of vaporizer.And work as temperature control part 57 and survey When obtaining the temperature in cold tanks 50 less than default low temperature value, the control first switch of temperature control part 57 part 60 is closed.And when the When one switch block 60 is closed, second switch part 70 is opened, 10 continuous firing of compressor, and now, from 10 drain of compressor The working media of the High Temperature High Pressure for going out directly is drained in condenser/evaporator 40 by second switch part 70, now condensation evaporation Device 40 plays a part of condenser 20, and heat is conducted in condenser/evaporator 40 working media the water in cold tanks 50. When the temperature that temperature control part 57 is measured in cold tanks 50 is higher than default high temperature value, the control first switch of temperature control part 57 part 60 Open.And when first switch part 60 is opened, second switch part 70 is closed, condenser/evaporator 40 plays the work of vaporizer again With the water in cold tanks 50 is absorbed heat and lowered the temperature again.So circulate, the water in cold tanks 50 may remain in all the time Between the low temperature value and high temperature value of the setting of temperature control part 57, the water in cold tanks 50 is made in relative constant temperature so as to reach State.

As for the mode that temperature control part 57 controls first switch part 60, first can be sent data to by temperature control part 57 and be opened GUAN spot part 60, so that realize the control to first switch part 60.And temperature control part 57 can include processor and temperature sensor, The processor can adopt known PLC, MCU etc..

Temperature control part 57 connects second switch part 70 with the control being turned on and off to second switch part 70.

Above-mentioned, the connection of temperature control part 57 second switch part 70, and to second switch part 70 be turned on and off control System, be due to the working condition of second switch part 70 with the working condition of first switch part 60 be contrary, and because control Warm part 57 can control being turned on and off for first switch part 60, so the unlatching of the control second switch of temperature control part 57 part 70 Or close and can reach contrary with the working condition of second switch part 70 work of working condition of first switch part 60 and imitate Really.Need it is further noted that being turned on and off for the control second switch of temperature control part 57 part 70, can pass through temperature control part 57 First switch part 60 is sent data to, so as to realize the control to first switch part 60.And temperature control part 57 can include place Reason device and temperature sensor, the processor can adopt known PLC, MCU etc..

First switch part 60 is fluid path electromagnetic valve.

Above-mentioned, first switch part 60 is fluid path electromagnetic valve, as condenser 20 is to connect choke valve 30 by electromagnetic valve, And the state of working media is liquid from condenser 20 to choke valve 30, so first switch part 60 is fluid path electromagnetic valve.Liquid Way solenoid valve receives the data signal of temperature control part 57, executes the action being turned on and off.

Second switch part 70 is hot gas bypass valve.

Above-mentioned, as compressor 10 connects condenser/evaporator 40 by second switch part 70, the state of working media from It is gaseous state that compressor 10 arrives condenser/evaporator 40, and second switch part 70 is hot gas bypass valve, when first switch part 60 is closed When closing, the working media of the output of compressor 10 reaches hot gas bypass valve, due to 10 continuous firing of compressor, gaseous working media Pressure in hot gas bypass valve side persistently increases, when the pressure that hot gas bypass valve is subject to is more than marginal value, hot gas bypass valve To open, gaseous working media reaches condenser/evaporator 40 by hot gas bypass valve.So, second switch part 70 is steam Bypass valve, can be when first switch part 60 be closed, and second switch part 70 is opened.When first switch part 60 is opened, The working media of the output of compressor 10 is closed by condenser 20, the reduced pressure of hot gas bypass valve side, hot gas bypass valve.From And realize that, when first switch part 60 is opened, second switch part 70 is closed.
