Description
Technical field
The invention belongs to the extraordinary electric room cooling technology field of ship, and in particular to a kind of constant temperature cooling-water machine peculiar to vessel
Group.
Background technology
The current extraordinary electric room tempering air processor of ship（AHU）Supporting handpiece Water Chilling Units, mostly using routine
Marine cooling-water unit, the fluctuation of chilled water leaving water temperature is 1 ~ 5 DEG C, and temperature fluctuation range is wide.
Shortcoming/deficiency of prior art：Existing outfit special vessel handpiece Water Chilling Units technology causes chilled water leaving water temperature, stream
Amount can not be constant, and fluctuation range scope is wide；Turning handpiece Water Chilling Units leaving water temperature fluctuation range down manually can cause high frequent to open
Stop or unload magnetic valve not stop to load and upload, reduce the service life of compressor；The fluctuation of chilled water leaving water temperature causes sky greatly
Gas disposal machine（AHU）Air-out fluctuation make it that greatly Electronic cooling is insufficient；The Energy Efficiency Ratio of unit is small, wastes ship energy.
The content of the invention
The problem of big temperature can not be constant is fluctuated in order to solve general handpiece Water Chilling Units chilled water leaving water temperature, unit energy is improved
Effect ratio, the present invention provides a kind of constant temperature handpiece Water Chilling Units peculiar to vessel.
Constant temperature handpiece Water Chilling Units peculiar to vessel, including compressor, air-cooled condenser, expansion valve, evaporator, constant temperature converge water tank, returned
Water pump and circulating pump, in addition to temperature sensor, electric heater, flow sensor and triple valve, the temperature sensor are set
On chilled water pipe, when temperature sensor detects chilled water temperature fluctuation, central control system control electric heater action,
Make chilled water temperature balance in setting value；The flow sensor is arranged in chilled water pipe, when flow sensor detects stream
When amount is mismatched with design discharge, central control system control threeway valve events adjust the flow of chilled water, make chilled-water flow
Balance is in setting value.
Further, the compressor is digital scroll compressor.
Compared with prior art, the principle of the invention, simple in construction, the small, systematic energy efficiency ratio of temperature difference fluctuation are high, and overall operation takes
With than relatively low.
Brief description of the drawings
Fig. 1 is present system work sheet.
Embodiment
As shown in figure 1, system inner refrigerant compresses through compressor 1, the refrigerant gas of HTHP is discharged, through air-cooled cold
After condenser 2 is cooled down, the refrigerant heat of discharge is taken away by air, and refrigerant became the subcooled liquid of cold anticyclone, expanded valve 3
After throttling, the refrigerant liquid as low-temp low-pressure, refrigerant liquid is steamed in evaporator 4 by the heat of absorption refrigerating water
Hair, is then sucked by compressor 1 and is thus again introduced into compressor 1, go round and begin again circulation.
The chilled water that evaporator 4 comes out delivers to constant temperature and converges water tank 5, is returned again by back water pump 6 after heat exchange in water tank 5
To evaporator 04.Constant temperature converges the chilled water that the side of water tank 5 comes out and is delivered to air processing machine by circulating pump 7（AHU）, when cold
When freezing the detection temperature of temperature sensor 8 fluctuation on water pipe, electric heater 9, PID regulations are signaled to by central control system
The energy of electric heater 9, makes chilled water temperature balance in setting value.Freezing water route on flow sensor 10 detect flow with
When design discharge is mismatched, triple valve 11 is signaled to by central control system, PID changes the flow chilled water flow of chilled water
Amount balance is in setting value, through air processing machine（AHU）Surface cooler changes high temperature chilled water after processing and turned again to by water circulating pump 7
Water tank 5.
