A kind of control method of the direct radiation cooling heating-type environmental control system of seawater, comprising the following steps:

(1) cooling in summer

A, when ocean temperature is higher than 18 DEG C and when being lower than 24 DEG C, as the seawater of refrigerating medium, it is sent directly into radiation mode Block flows out again after being freezed, and adjusts the air duct valve in refrigerated dehumidification module in the first air duct, reduces in the first air duct Air demand increases the air demand in the second air duct.At this point, the air duct valve portion in the first air duct is opened, controlling opening of valve； Meanwhile needing to dehumidify in process of refrigerastion, when through refrigerated dehumidification module, humidity reduces air；Therefore, the production of indoor refrigeration duty It is raw, Radiation Module is come not only from, while hybrid refrigerated dehumidification machine assumes responsibility for the refrigeration duty of a part；

Specifically, seawater is pumped by total water pump 11 from outside, it is sent into heat exchanger 3 via total valve 12 and the first valve 13, Water in freezing unit 4 is frozen the extraction of water pump 41, and the first freezing water valve 42 is opened, seawater and chilled water in heat exchanger 3 into The exchange of row heat, seawater after cooling enter water header 84 from radiant panel entrance 81 and via radiation plate and flow through check-valves 31 is subcooled Radiation refrigeration is carried out into radiant panel 8 is entered, finally header 85 is discharged from 82 outflow of radiant panel outlet and via radiation plate and flows out；

B, when ocean temperature is lower than 18 DEG C, as the seawater of refrigerating medium, Radiation Module can be sent directly into and freezed It flows out again afterwards；Indoor temperature control is controlled by the adjusting of water supply；Meanwhile it being removed in process of refrigerastion through refrigerated dehumidification module It is wet；Air duct valve wide open in dehumidification process in the first air duct, indoor humidity adjust the aperture that water valve can be freezed by adjusting To adjust；When the temperature of radiant panel is lower than indoor air temperature, the temperature of radiant panel is controlled by the adjusting of the second valve, So that radiation plate surface does not condense；

Specifically, the seawater as refrigerating medium does not need to be pre-processed, it is straight by total valve 12 and third valve 15 It picks after radiant panel 8 is freezed from 82 outflow of radiant panel outlet and plate water outlet header 85 outflow via radiation；

Refrigerated dehumidification module in step a and b includes freezing unit and hybrid refrigerated dehumidification machine, is dehumidified in step a Refer to that fresh air enters from fresh wind port with ventilation, it is processed after filter is mixed with cabin room air, it is discharged, comes through exhaust outlet Hybrid refrigerated dehumidification machine is sent into from the fresh water chilled water of refrigerating water sets, and dehumidifying and cooling is carried out to room air, the water after condensation It is discharged via drain valve, air duct valve is opened in refrigerated dehumidification process, and aperture is at 0.2-0.8 °；

In step b, dehumidifying refers to that fresh air enters from fresh wind port, processed after filter is mixed with cabin room air, It is discharged through exhaust outlet, the fresh water chilled water from refrigerating water sets is sent into hybrid refrigerated dehumidification machine and is removed to room air Wet, the water after condensation is discharged via drain valve, and air duct valve portion is opened in dehumidification process, and aperture is 1 °；

C, when ocean temperature is higher than 24 DEG C, or when Radiation Module and refrigerated dehumidification module can not absorb whole heat together When load, assisted refrigeration module is opened, and carries out cooling processing to cabin simultaneously with refrigerated dehumidification module；

D, it needs to dehumidify and divulge information in process of refrigerastion, fresh air enters from fresh wind port 9, mixes with air in cabin 6, through air draft Mouth 10 is discharged, and a part of water from refrigerating water sets enters heat exchanger 3 when summer, ocean temperature was higher and seawater carries out heat Exchange, another part are sent into dehumidifier 7 and dehumidify to room air, and the water after condensation is discharged via drain valve 71；

(2) winter heating

When needing to heat, heating module is opened, and the fresh water in fresh-water pool is received in boiler 2 and is heated to it, sea Water enters Radiation Module after being exchanged heat in heat exchanger 3 with the heat source from boiler 2 and carries out heat supply, specifically: the second valve 14 open, after seawater is exchanged heat in heat exchanger 3 with the heat source from boiler 2, via hot check-valves 32 enter radiant panel 8 into Row heat supply.

During air-conditioning work, control cabinet 55 controls the valvular switch of institute in the system, guarantees the safety of whole system Operation.

The advantage of technical solutions of the utility model is:

1, seawater is directly as refrigerant, in 1 year a big chunk time of summer we directly use seawater as Cold source exchanges heat, and the utilization rate of cold energy is high, and structure is simple, relatively more energy saving.

2, in the processing of fresh air, the utility model is not as traditional air-conditioning carries out the processing of air, but by air It directly blows after filtering.Such benefit is that ship's space is to want fresh air volume with the difference in ground room first Ask relatively high, the fresh air volume of this air-supply is high and comfort is strong, avoids the secondary pollution etc. of return air during processing Factor；

3, in the processing of humidity, we devise hybrid refrigerant dehumidification system, while meeting humidity processing, It can also assist generating the effect freezed.Especially when ocean temperature is lower than 18 DEG C, freezing unit only needs to handle room air for it The load of humidity, unit is smaller, relatively energy saving；

4, traditional auxiliary cooling system is provided under extreme conditions, therefore this system is no matter from energy consumption or structure It is relatively more simple, more environmentally-friendly.

Basic principles, main features, and advantages of the present invention has been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model Claimed range is defined by the appending claims and its equivalent thereof.
