It is interrupted for user side heat supply.Water after anti-defrosting and the water after frost thawing all pass through liquid dish 15 and enter in solution pool 16, when
When solution pool 16 reaches certain liquid level, open valve 29, close valve 28, now pump 17 from solution pool pump water to spray thrower.
When solution pit level is too high, valve 27 can be opened and discharge water.After anti-defrosting terminates, close heater 5 and pump 17.In order to anti-
Only in solution pool, the too low icing of water temperature causes line clogging, can regularly open water in 27 solution pools of valve and drain.
Example 4
Referring to Fig. 4, heater is arranged in heat source tower solution pool, Fig. 4 and Fig. 1 compares, simply by heater 5 from load
Cryogen transmission pipeline 4 is changed in heat source tower solution pool 16, coats heat-insulation layer in solution pool 16 outer wall and spray liquid transfer tube 18,
Heater 5 is electric heater unit or hot water, deep fat or hot gas heat exchanger, electric heater unit length l or heat exchanger heat exchange area
Determined by the maximum heat that anti-defrosting needs, the heat-insulation layer of solution pool 16 outer wall coats whole solution pool outer wall, and spray liquid transmits
Heat-insulation layer length l of pipe 18 ' it is spray liquid transfer tube 18 length from pump 17 to spray thrower 3.Heat source tower solution pool is symbol
Close the water for industrial use of technological requirement.When needing anti-defrosting, open heater 5, after shower water heating in solution pool, then beat
Drive heat source tower spray liquid circulating pump 17, hot water passes through spray liquid transfer tube 18, spray thrower 3 is sprayed onto on heat exchanger 14, heat exchanging
Device carries out anti-defrosting.The refrigerating medium that now source pump 8 is transmitted through coming still can absorb heat in heat source tower heat exchanger 14, heat
Pump assembly can be uninterruptedly user side heat supply.After recirculated water in solution pool and frost thawing, water returns to solution by liquid dish 15
In pond 16.When liquid level is too high in solution pool, valve 27 can be opened and discharge water；When liquid level is too low, can open fluid infusion valve 28 to
Moisturizing in solution pool.When heater is electric heater unit, need first to check liquid level in solution pool before heating it is ensured that liquid level
Flooding electric heater unit completely, to prevent electric heater unit dry combustion method, simultaneously need to making regular check on electric heater unit, preventing from leaking electricity.
