Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, the utility model discloses a kind of system and device being applicable to northern area outdoor cold source in winter and reclaiming, air-cooler absorbs low-temperature receiver and carries original medium refrigerating mediums such as () water, salt solution, calcium chloride, alcohol, ethylene glycol by original refrigerating water pump, and alternative handpiece Water Chilling Units completes a kind of refrigeration cycle; Jet chimney is exported by a plate type heat exchanger and original refrigerating water pump and complete an antifreeze circulation on the pipeline of outdoor air cooler entrance.Whole system is divided into two regions to be respectively cooling cycle system and the antifreeze circulatory system.
Cooling cycle system comprises air-cooler, original chilled water pump, electric turbine butterfly valve, temperature controller and expansion tank.Air-cooler and outdoor temperature controller are placed in outdoor, and other are positioned at indoor.Air-cooler is dry cold blower fan, adopts poling fin cold blower fan.Water pressure gauge is remote water pressure table.
Air-cooler can adopt one, also can adopt multiple; If adopt multiple, then using after the entrance parallel connection of multiple air-cooler as the entrance of a total air-cooler, as the outlet of a total air-cooler after the outlet parallel connection of multiple air-cooler, the refrigeration work consumption that can require according to user selects the quantity adopting air-cooler.
The outlet of air-cooler and being connected by pipeline for export of former handpiece Water Chilling Units; This pipeline is provided with temperature controller Tn2 and expansion tank 11, y-type filter 9, is also provided with temperature controller Tn and locates for export close to former handpiece Water Chilling Units; The entrance of air-cooler exports with original refrigerating water pump, former handpiece Water Chilling Units entrance is connected, and on the connecting line of this section, being provided with indoor temperature transmitter 4, water pressure gauge 5, turbine butterfly valve and electric turbine butterfly valve 15, former handpiece Water Chilling Units porch is provided with another electric turbine butterfly valve 14.
Cistern or user's end water return outlet connect the water sucking mouth of refrigerating water pump 8 by pipeline, and the delivery port of refrigerating water pump 8 is connected by the entrance of pipeline and air-cooler 1, handpiece Water Chilling Units 16 entrance.The delivery port of refrigerating water pump 8 and the entrance pipe of air-cooler 1 are provided with electric turbine butterfly valve 15, are provided with electric turbine butterfly valve 14 with the pipeline of handpiece Water Chilling Units 16 entrance.
Cooling cycle system operation principle:
When detecting outdoor temperature Tw≤-10 DEG C, starting air-cooler, starting refrigerating water pump 8, open electric turbine butterfly valve 15, close electric turbine butterfly valve 14, original system medium circulates in cooling cycle system; When desired value (as 2 DEG C) of the temperature that Tn2 detects≤user's setting, blower fan in air-cooler is out of service, when desired value (as 2 DEG C) of the temperature > user setting that Tn2 detects, air-cooler variable frequency starting, original system medium temperature in Tn2 moment signal piping, when original system medium temperature is close to desired value 1 DEG C, air-cooler keeps existing conversion frequencies to run, and ensures the constant temperature circulating of original system medium.Water pressure gauge 5 is for the pressure of display medium.Expansion tank 11 supplements medium, the normal operation of medium in equalizing line time not enough for medium in medium pipeline, ensures that in pipeline, the moment is full of medium.
Whether Tn Real-Time Monitoring medium temperature reaches design temperature (the present embodiment is 2 DEG C); If Tn> design temperature, then open electric turbine butterfly valve 14 and start handpiece Water Chilling Units 16 with 50% Power operation; Tn≤design temperature, stops handpiece Water Chilling Units 16 and closes electric turbine butterfly valve 14.Therefore area northeastward, when outdoor environment is lower, native system can substitute the ability that original handpiece Water Chilling Units 16 completes refrigeration, thus reaches energy-conservation, reduces the object of operating cost.
The antifreeze circulatory system comprises plate type heat exchanger 7 and magnetic valve 13; The two ends once entering, export the turbine butterfly valve respectively on turbine butterfly valve access kind of refrigeration cycle supply channel of plate type heat exchanger 7; Secondary enters, outlet enters with steam through gate valve respectively, exports and be connected; Gate valve outside secondary entrance and the pipeline between steam inlet are provided with magnetic valve 13.
Antifreeze circulatory system operation principle:
Keep 20-30 minute when detecting outdoor temperature Tw≤0 DEG C, at interval of 1-2 hour startup magnetic valve 13, external high temperature steam (130 DEG C) is through the secondary entrance of plate type heat exchanger 7, export with cooling cycle system Central Plains refrigerating water pump 8 medium entered in plate type heat exchanger 7 entrances through kind of refrigeration cycle supply channel and carry out exchange heat, ensure medium temperature cannot reach crystallization temperature, make medium freeze, can normal circulation.
Air-cooled energy recovery unit, first project place determines that temperature on average can reach less than-10 DEG C (northern areas) in the winter time.By off-premises station and natural cold air forced heat-exchanging, the water in off-premises station heat exchanging water pipe is lowered the temperature, by valve transfer, the water after heat exchange is transported in user side stand-by.
Control content: the condition that comes into operation outdoor temperature-10 DEG C.Before running, system manually-operated gate is all opened.
Cooling cycle system: the medium in original system is determined according to applying working condition (>=2 DEG C its be water; < 2 DEG C its be antifreeze medium, but medium must meet freezing point temperature lower than the outdoor lowest temperature).Circular flow is to former refrigerating water pump-electric turbine butterfly valve 15-distance-transmission pressure gauge-temperature controller Tn1-outdoor air cooler entrance-air-cooler-outdoor air cooler outlet-expansion tank 11-temperature controller Tn2-Y type filter-refrigerating water pump suction inlet.By refrigerating water pump pump drive medium and outdoor air cooler heat exchange, when outdoor temperature Tw≤-10 are spent, open electronic dish valve M1, close electric butterfly valve M2.When the temperature that temperature controller Tn2 shows is desired value, outdoor air cooler is startup optimization blower fan not.Otherwise then start blower fan, fan starting quantity 25%, 50%, 75%, 100% variable frequency starting gradually, when temperature controller Tn2 is close to desired value+1 DEG C in start-up course, keep now fan starting amount, to ensure to realize most power save mode.Tn1 object detects for liquid temp.Expansion tank is the device of system fluid infusion, for system loss or evaporation cryogenic fluid.
The antifreeze circulatory system: the circulation of plate type heat exchanger two side is steam import and export, plate type heat exchanger side import and export the pipeline being jointly connected to refrigerating water pump outlet along the line on, its plate type heat exchanger side arranges turbine butterfly valve in the middle of importing and exporting, this valve be arranged at kind of refrigeration cycle supply channel along the line on, this turbine butterfly valve effect is the rate-of flow regulating the antifreeze circulatory system of shunting.When system Tn2 temperature detection is lower than 0 DEG C, jet chimney solenoid is opened after 20 ~ 30 minutes and is automatically closed.
