Description
Technical field
The present invention relates to a kind of seagoing vessel a/c system, particularly a kind of seagoing vessel a/c system that utilizes subsurface sea water cool capacity belongs to the Marine engineering technical field.
Background technology
In the existing ship's air conditioning system, artificial keeping of low-temperature receiver all needs to consume a large amount of electric energy, overcomes the resistance that working medium flows and the electric energy that consumes only accounts for sub-fraction, and therefore, traditional marine air-conditioning system all can not reach the target that cuts down the consumption of energy significantly.In the prior art, application number is CN200410024766.X, name is called the patent of invention of " ship energy saving a/c system ", it is the cold that utilizes the water-cooled double-bottom space in hull bottom off-lying sea to provide, when high temperature, force outside air to flow through and be subjected to the water-cooled double-bottom space in hull bottom off-lying sea, cooled cold air imports the marine air conditioning plumbing system and makes indoor cold air conditioner usefulness, though need not energy resource consumption, simple in structure, but the temperature of the outer seawater of hull bottom is near normal temperature, the cold that comprises is very faint, the poor effect of coolant air.In China, the coastal subsurface sea water degree of depth is between 10-300 rice, and temperature 12-20 ℃, even low reach 6-12 ℃ is the good natural cold source of air-conditioning.Sea table annual megadyne temperature with reference to the whole world distributes, and the vertical distribution of global ocean broadwise annual megadyne temperature, even spend marine site between south latitude 30 degree at north latitude 30, temperature reaches 35 ℃ or when higher, sea surface temperature is high slightly, drop to 100 meters-120 meters the degree of depth, sea temperature also remains on 22 ℃ below-24 ℃.Therefore, even in the most hot season, the coastal temperature that is positioned at the subsurface sea water under the top layer is still enough low, and the degree of depth is limited, takes conveniently, and itself can directly make the natural cold source of air-conditioning.
Summary of the invention
For deficiency and the defective that overcomes prior art, the invention provides a kind of marine air-conditioning system that utilizes subsurface sea water cool capacity.This system need expend the small amount of electrical energy except flowing of working medium, is not required to be the low-temperature receiver consumed power, has saved most of power consumption, is a kind of a/c system of economical and efficient.
The present invention is achieved through the following technical solutions.The present invention is made up of air processor, seawater feedway and seawater drawing device three parts.Air processor is a horizontal drum, and the flow direction along air is furnished with from left to right successively: return air inlet and fresh inlet, air register, air-mixing chamber, air filter, blower fan, aircooling cabinet, drain pipe, manger, air chamber and blast pipe.The used air of air conditioned cabin is flowed into by return air inlet, and fresh air is flowed into by fresh inlet, and two strands of air flow through air-mixing chamber and air filter through air register, and the air after the filtration flows through blower fan under the suction function of blower fan, enter air cooler.Air cooler is water-cooled, and refrigerant is natural Mare Frigoris water.Mare Frigoris water from bottom to top passes the fin tube in the air cooler, and air laterally skims over the outside of fin tube, fully absorbs the cold of Mare Frigoris water, flows to manger in cooling, flows through the air chamber then and enters blast pipe.When air was cooled in cooling vessel, airborne a part of condensation of moisture was a water, stayed along fin tube, and windstream is when manger, because the complications of runner are also under some moisture flow.Two bursts of condensate water are all discharged by drain pipe.The cold air that flows out in the blast pipe will be introduced the air outlet in each cabin, the effect of performance air-conditioning temperature-reducing.
The main body of seawater feedway is a sea water pump, and the seawater of being introduced by inferior skin depth is pumped by sea water pump through flood valve, through outlet valve, seawater pipe, enters air cooler by the air cooler bottom, goes out air cooler by overhead stream again, enters the sea then.
When the flow that measures on the flows/temperatures measurement point obviously reduces, deep water pipeline section generation choking phenomenon is described, should open shallow water flood valve and shutoff valve, close flood valve and outlet valve, suck the seawater of shallow water depth by the shallow water pipe, pumped into the deep water pipe by sea water pump through shutoff valve, flow back to the sea from seawater time skin depth again.At this moment seawater returns the process of raising will wash the deep water pipeline section, reach the purpose of dredging pipeline.After the mediation, flood valve and outlet valve are opened again and are entered normal working, and shutoff valve and shallow water flood valve are closed again, cut off back and raise the loop.
In the seawater drawing device, deep water pipe and India rubber tube are by the clamp leak-tight joint, and India rubber tube is the sebific duct that inside accompanies wire gauze, can bear the pressure of 3 MPas.The end of India rubber tube is import, and device has the filtering net head, in case the suction of fish, algae.India rubber tube can be as required through roll shaft and by winch volume strand, or on receive or transfer, sink the degree of depth of seawater with adjustment.When close river mouth of seagoing vessel or harbor district, the filtering net head should rise to the position of 2 meters of the depth of waters, this system halt work, the state of resuming work again after going to sea.When seagoing vessel navigates by water in marine site, the Bohai Sea; the filtering net head remains on the degree of depth of 10-12 rice; when seagoing vessel navigation other marine site at coastal area of china; the filtering net head remains on the degree of depth of 50-80 rice; when seagoing vessel navigation in the off-lying sea or during other marine site; remain on the degree of depth of 80-100 rice, determine according to the water temperature reading that the flows/temperatures measurement point obtains.
The present invention has substantive distinguishing features and marked improvement.The seagoing vessel a/c system of this invention does not need to keep the low-temperature receiver consumed energy for air-conditioning fully, has saved the most energy consumptions in the traditional air-conditioning system, is a kind of a/c system of efficient, economic, cleaning.The simple and compact structure of total system, cheap, it is narrow and small to take up room, and it is convenient to use, and can adopt the different degree of depth that draws water in different waters, flexible, motor-driven, energy-conservation, and promotion prospect is widely arranged, and has tangible economic benefit and social benefit.
