Description
Technical field
The present invention relates to use heat pump techniques on a kind of boats and ships, specifically obtain energy-efficient, environmental protection with lower cost
Heat pump, particularly relates to the recovery type heat highly effective sea-water source heat pump of a kind of changeable control making full use of Ship Waste Heat, belongs to
In air conditioner technology field.
Technical background
Along with improving constantly of global economic integration degree, more than the 90% of world's freight traffic, mainly by boats and ships, consumes
Substantial amounts of fossil energy, is the principal element causing marine pollution.How to realize the energy efficiency of shipping transport, improve boats and ships
Operation comprehensive energy efficiency coefficient, reduces the discharge of pollutant, it has also become the important topic that shipping world increasingly pays close attention to.As accounting for boats and ships
The marine air-conditioning system of energy consumption 20%, saves energy and reduce the cost by using novel ship air-conditioning technical to realize it, energy comprehensive to shipping transport
The raising of effect coefficient is significant.Seawater source heat pump technology is to adapt to that the strategy of sustainable development requires and the one that develops is novel
The air-conditioning system integrating refrigeration, heating, there is energy-efficient, the advantage of environmental protection.
At present, marine air conditioner substantially uses conventional air-cooled or water-cooling system, and minority marine air conditioner utilizes seawater to do Cooling and Heat Source.Shen
Please number be the patent of 201120030749.2, disclose a kind of seawater source heat pump air-conditioning system for ship, mainly by refrigerant circulation system
System, hull bottom heat transferring medium cyclic system and air-conditioner water system composition.This air-conditioning system is the integrated circuit constituted by polyethylene coil pipe
It is arranged on hull bottom, makes seawater medium directly and in coil pipe carry out heat exchange, simultaneously because the turbulent flow formed of running at high speed of steamer,
Greatly strengthen the heat exchange efficiency of coil pipe, reach energy-efficient purpose in theory.But, the actual motion effect of this system
It need discussion.First, the heat exchange efficiency of coil pipe is affected relatively big by ship's speed, when marine low speed travels or berths, coil pipe
Heat exchange efficiency reduces rapidly, and then causes the whole efficiency of this air-conditioning system to be greatly lowered.Secondly, in Practical Project, boats and ships belong to
In flowing carrier, different with its navigation area, the temperature of the low-temperature heat source (seawater) of heat pump is continually changing, when boats and ships walk to sea
When coolant-temperature gage is less than the marine site of 10 DEG C, this air-conditioning system has been not normally functioning even cannot be run.

This system is that gas engine burning natural gas drives generator, and electrical power generators drives heat pump to produce a part of heat；Gas engine simultaneously
The flue gas produced enters in waste heat boiler, condensing heat exchanger and absorption heat pump absorb respectively flue gas that waste heat boiler gives off and
Steam, in condensing heat exchanger liberated heat input absorption heat pump, thus provides another part heat, carries to a certain extent
The high whole efficiency of system, has reached the purpose of energy-conserving and environment-protective, but the most unsatisfactory.First, this system waste heat reclaims
Utilization rate is relatively low, and medium water temperature only improves 2 DEG C, and system effectiveness improves about 6%, and energy-saving effect is the most inconspicuous.Secondly, exist
During Ship Anchoring, main frame quits work, now recyclable without waste heat, and the difficult problem that ocean temperature is low still exists, and this system exists
The marine site that ocean temperature is low still cannot be run.And, the volume of gas turbine is very big, is generally used for the boats and ships that displacement is big
On, range of application is restricted.Current most of boats and ships all use the reciprocating diesel engines in internal combustion engine as main frame,
Power is provided for boats and ships.Ship Waste Heat resource is the abundantest, main frame as the power and energy center of boats and ships, the only heat of 50%
Amount is converted to useful work, and remaining heat is pulled away the most in every way, is broadly divided into jacket-cooling water waste heat and diesel exhaust gas
Two kinds of forms of waste heat.Marine main engine is the high-power diesel engine of the most up to ten thousand kilowatts of a few megawatt, and the temperature of its jacket-cooling water is
70 DEG C～95 DEG C, its exhaust gas temperature 300 DEG C～450 DEG C；And the medium seed diesel engine that generator power is 200kW～400kW, its
The temperature of cooling water is 65 DEG C～80 DEG C, and exhaust gas temperature is 300 DEG C～400 DEG C.These waste heats all can be as sea water source heat pump
Auxiliary thermal source.Therefore, land technology Marine had Practical significance very much.
