Description

A kind of boat-carrying heat pump type air conditioning system and heating refrigerating method
Technical field
The present invention relates to marine air conditioning technical field, more particularly to a kind of boat-carrying heat pump type air conditioning system and heating refrigeration side Method.
Background technology
At present, for the medium and small-scale vessel such as civilian fishing boat, yacht mainly using internal combustion engine as power, internal combustion engine subject matter is fuel Burning can produce pollution environment waste gas, fuel leakage can polluted water region, these pollution for aquaculture, growth waters or It is that the influence at the scenic spot waterborne of Amenities will be far longer than general area.And very big noise can be sent during internal combustion engine, Interference is brought to shipboard operation, leisure and rest.To tackle this problem, the technology using fuel cell as ship power is gradually developed Out.Because traditional ship air-conditioning can utilize fuel engines heat to heat in heating, and the air-conditioning system of fuel cell ship System is then difficult by heat of engine heating, it is impossible to provides the thermal source as marine air conditioning winter heating, therefore, in the prior art Fuel cell ship using heat pump type air conditioner system, it is necessary to heated and freezed, and the heating of heat pump type air conditioner system air-conditioning Power consumption is higher.
Ship heat pump type air conditioner system principle is exactly that under heating condition, heat exchanger is in cabin using inverse Carnot's principle Condenser, cabin external heat exchanger are evaporator, evaporator from the environment thermal energy in outdoor air draw heat with evaporation heat transfer Working medium, refrigerant vapor pressure and temperature after compressor compresses rises, when high-temperature vapour is condensed into liquid by condenser, release The heat transfer gone out gives space in the cabin with heat, and condensed heat-transfer working medium returns to evaporator, Ran Houzai by expansion valve Evaporated, so moved in circles.Under cooling condition, cabin external heat exchanger is condenser, and heat exchanger is evaporator in cabin, is steamed Draw heat in heat energy of the device out of cabin in the air of space is sent out to press after compressor compresses with evaporation heat transfer working medium, refrigerant vapor Power and temperature rise, when high-temperature vapour is condensed into liquid by condenser, the heat transfer that discharges to outdoor, condensed biography Hot working fluid returns to evaporator by expansion valve, is then evaporated, so moved in circles again.However, ship heat pump type air conditioner system The shortcomings that system is that heating load is smaller when the outer air themperature of cabin is lower, particularly when air themperature is less than -5 DEG C outside cabin, heat Pump is just difficult to normal work, it is necessary to which electricity consumption or other auxiliary thermal sources heat to air, and the efficiency of heat pump substantially reduces.Ship Heat pump type air conditioner system is under heating condition, it is necessary to periodically defrost, defrosting building block technique can refer to China for meeting frosting on evaporator Patent application 201210152219.4 is used for Defrost method, a kind of 201410108455.5 heat pump air conditioners of air source heat pump system Defrosting control method and heat pump type air conditioning system, air source heat pump increase defrost after module, not only stability reduction, maintenance cost Increase, and lose a large portion energy.

    B. under heating condition, heat exchanger turns into condenser in cabin, and cabin external heat exchanger turns into evaporator, high temperature residual air arrange to Air residual air blender, and be mixed into medium temperature mixed gas with outside air and transfer to cabin external heat exchanger, in cabin external heat exchanger In, medium temperature mixed gas exchanges heat with working medium, is discharged after changing into low-temperature mixed gas；The electric energy of fuel cell output turns through electric power It is compressor, delivery pump and marine propuision system power supply after changing system conversion；
    C. under cooling condition, heat exchanger turns into evaporator in cabin, and cabin external heat exchanger turns into condenser, high temperature residual air arrange to It is extraneous；The electric energy of fuel cell output is that compressor, delivery pump and marine propuision system supply after electric power coversion system is changed Electricity.
  7. 7. the heating refrigerating method of boat-carrying heat pump type air conditioning system according to claim 6, it is characterised in that：The pressure of heat pump air conditioner Contracting machine and marine propuision system feed back to ship control system, ship control system in the course of the work, by real-time power demand System controls an appropriate number of methanol-water reformation hydrogen production power generation module group to operate according to real-time power demand information, and controls methanol-water Storing and conveying device conveys first alcohol and water raw material to the methanol-water reformation hydrogen production power generation module group of operating；When instant power demand compared with Hour, control less methanol-water reformation hydrogen production power generation module group to operate, when instant power demand is larger, control more first Alcohol water reformation hydrogen production power generation module group operates.
  8. 8. the heating refrigerating method of boat-carrying heat pump type air conditioning system according to claim 6, it is characterised in that：In heating condition Under, temperature sensor detects the mixed gas temperature in air residual air blender in real time, and temperature information is fed back into control dress Put, control device adjusts the feeding amount of outside air by fan, to control the temperature range of mixed gas in 15~60 DEG C.
