Abstract
The invention discloses a water-cooling heat pump hot-water unit for cooling engine rooms of ships, which comprises a refrigerant circulating system and a post air supply system, wherein the refrigerant circulating system comprises basic parts of a post air supply outlet, a compressor, a condenser, an expansion valve, an evaporator and the like. In the machine set, on the basis of the heat pump fundamental principle, the heat recovery principle of the condenser and the fundamental principle of post air supply, and for changing the current situation of large unit heating loads and areas, high temperature all the year around, dispersed operating posts and overhigh temperature in the engine rooms of the ships and solving the problem that the conventional central air conditioning unit reduces the temperature blindly in an integral area, does not have a heat recovery function and is low in heat efficiency when applied to the engine rooms of the ships, a double-effect water-cooling heat pump unit which meets the characteristic of air conditioners of the engine rooms of the ships and has the pertinent functions of post air supply and sanitary hot-water recovery is developed. In addition, in the water-cooling heat pump hot-water unit, energy is utilized effectively, and the cascade utilization of the energy is realized.
Description
Affiliated technical field
The present invention relates to a kind of source pump, especially the economic benefits and social benefits water cooling heat pump unit of post air-supply and health hot water function is used and is with in the watercraft engine room cooling.
Background technology
Be provided with the device that diesel main engine, diesel-driven generator etc. discharge a large amount of heats in the cabin of steamer, cause temperature in the cabin throughout the year all more than 40 ℃, can reach 50 ℃ summer, high like this temperature all has very big harm for physical and mental health and the operating efficiency of staff in the cabin.Therefore, in science and technology relatively advanced present age, it is the work that must carry out that the cabin is lowered the temperature, and all is very significant to staff's body and mind and safety of ship operation.Yet general cabin area is all bigger, the thermic load of unit are is also very big, and staff's job site relatively disperses, and is not only nonsensical if whole cabin is lowered the temperature, but also caused a large amount of energy wastes.
Since 08 year, about 2000 of the annual new shipbuilding oceangoing ship of China, the unit demand special-purpose to the cabin cooling is big.But, domestic still do not have this unit targetedly at present, and the common employing of some boats and ships is not freezed to the cabin with the cold blower fan group of wind (water) of heat reclamation device comprehensively, and not only refrigeration is bad, but also caused the waste of primary energy, brought burden to environment.
Under this background, the present invention proposes the cold and hot pump hot water machine group of a kind of watercraft engine room cooling water, only to the cooling of blowing of the relatively more fixing work position of personnel in the cabin; Simultaneously, reclaim a large amount of heat resourceses in the cabin, to carrying out the supply of health hot water on the boats and ships.The present invention has realized the cascaded utilization of energy theory, has improved efficiency of energy utilization.
Summary of the invention
In order to improve the working environment of personnel in the cabin, the invention provides the cold and hot pump hot water machine group of a kind of watercraft engine room cooling water, the temperature on the post not only can be reduced targetedly, but also waste heat supply health hot water in the cabin can be reclaimed.Simultaneously, the cold and hot pump hot water machine group of described watercraft engine room cooling water is a central combination, and factory formulates, and is convenient to on-the-spot installation.
The technical solution used in the present invention is:
1. in the refrigerant-cycle systems, compressor outlet links to each other with condenser inlet, condensator outlet links to each other with the expansion valve import, the expansion valve outlet links to each other with evaporator, evaporator outlet links to each other with compressor inlet, and this connected mode has been formed the refrigerant-cycle systems of sealing.Under this connected mode, the high-pressure refrigerant of compressor outlet after the condensation heat radiation, by entering evaporimeter after the expansion valve step-down, is got back to compressor after the evaporation heat absorption in evaporimeter in condenser, finish new round circulation; In the supply air system of post, return air inlet, filter, evaporimeter, blower fan, air outlet, post air outlet are linked in sequence.
2. comprise refrigerant flow path, health hot water runner and seawater runner in the condenser, described refrigerant flow path one end connects described compressor, the other end connects described expansion valve; Described health hot water runner one end through magnetic valve link to each other with the health hot water import, the outlet of the other end and health hot water links to each other; Described seawater runner one end through magnetic valve link to each other with sea intake, the other end links to each other with seawer outlet.When needing to produce health hot water, the sea intake system closing, health hot water enters condenser, eductor condenser after the condensation heat raising of absorption refrigeration agent self temperature; When not needing to produce health hot water, the health hot water import is closed, and the seawater of low temperature enters eductor condenser after the condensation heat of condenser absorption refrigeration agent.
3. comprise refrigerant flow path and distinguished and admirable road in the evaporimeter, described refrigerant flow path one end connects expansion valve, the other end connects compressor; Described distinguished and admirable road one end connects filter, the other end connects blower fan.Indoor return air through filter enters evaporimeter, and temperature behind the cold-producing medium of heat transferred evaporation heat absorption is reduced, and delivers to each air-supply post by blower fan and air outlet.
4. filter, compressor, condenser, magnetic valve, expansion valve, evaporimeter, blower fan are set in the unit casing; Return air inlet, sea intake, seawer outlet, health hot water outlet, health hot water import, six of air outlets and extraneous interface are set on the unit casing; The post air outlet links to each other with air outlet, and wind is delivered to each work position; This assembling mode is convenient to unit self-contained combination in factory, thereby has reached high efficient and reliable, the easy purpose of installation and maintenance.
The invention has the beneficial effects as follows:
1. during the routine work of the cold and hot pump hot water machine group of described watercraft engine room cooling water return air in the cabin is cooled off, reached the effect that reduces cabin temperature.
2. the cold and hot pump hot water machine group of described watercraft engine room cooling water is only to work position fixing in the cabin cooling of blowing, rather than the air-supply of random large tracts of land lowers the temperature, a large amount of saving the energy.
3. the cold and hot pump hot water machine group of described watercraft engine room cooling water has utilized the condensation heat of cold-producing medium to produce health hot water fully.Simultaneously, supply discontinuous characteristics at health hot water on the boats and ships, for the continuous operation of unit, salt water cooling system is worked when not supplying health hot water.
4. described sanitary hot water system and described salt water cooling system automatically switch according to health hot water actual load demand.
5. the cold and hot pump hot water machine group of described watercraft engine room cooling water is a central combination, and factory formulates, thereby has reached high efficient and reliable, the easy purpose of installation and maintenance.
