Description

Heat-pump-type fuel oil hot and cold water equipment
The utility model belongs to air-conditioning technical field, particularly the central air conditioning unit of being made up of refrigeration compressor, condenser, device for drying and filtering, restricting element, evaporimeter and vapour liquid separator.
Existing chilled water, hot water facility mainly contain following several, and the one, oil burning boiler, it is that the energy is produced hot water with diesel oil, its Energy Efficiency Ratio is smaller or equal to 0.95; The 2nd, boilers heated electrically, it produces hot water with electric energy, but its Energy Efficiency Ratio is smaller or equal to 0.95; The 3rd, lithium bromide fuel oil air-conditioning unit, it can produce cold water and hot water simultaneously, and its Energy Efficiency Ratio is 1.1~1.3.In a word, their energy conversion rate is all lower.And the above two can only heat water, can not freeze.In addition, the existing apparatus of air conditioning all is power with the electric energy, thereby under the area or the unallowed situation of net capacity of power tense, this air-conditioning unit can't move.
Carry out the device of air conditioner refrigerating when the purpose of this utility model is a kind of energy-efficient supply hot water (55~60 ℃) of design, its comprehensive Energy Efficiency Ratio Cop can reach more than 3.5, and, the multifunctional cold and heat wetting system that can use in the area of power tense.
Below, with reference to its structure of description of drawings.
It by refrigeration pipe 22 with refrigeration compressor 1, water cooled condenser 14 and 20, cooler 21, device for drying and filtering 23, restricting element 25, evaporimeter 26, valve 28 and vapour liquid separator 29 are connected in turn, and the two ends of valve 28 link to each other with the shell channel of cooler 21 by pipeline 22.Refrigeration compressor 1 links to each other with engine 4 by shaft coupling 2.The aiutage 3 of engine 4 is the structure of air-water heat exchanger formula.
In order to control the leaving water temperature of water cooled condenser 14,20 automatically, on their outlet pipe 11 and 16, be separately installed with temperature-sensing valve 9 and 17.
Above-mentioned engine 4 can be fuel oil (gas) engine or steam engine.
In order to control the temperature of jacket water, on its outlet pipe, be equipped with temperature-sensing valve 5.
Water cooled condenser 14 and 20 cooling water pipeline can be independent separately, also can contact mutually.The cooling water pipeline of engine 4 jacket water pipelines and aiutage also can be independent separately, or parallel with one another.
Malfunctioning in order to prevent temperature- sensing valve 5,9,17, the by-passing valve 6,12,18 in parallel with temperature- sensing valve 5,9,17 all is installed on outlet pipe.
Cooler 21 is a water cooled condenser formula structure, and its internal heat exchange tubes is connected between water cooled condenser 20 and the device for drying and filtering 23 by refrigerant line 22, and shell channel and valve 28 are in parallel.The triple valve that valve 28 can be installed in a certain end among its refrigerant line two ends, place replaces.
Restricting element 25 can be an expansion valve.
Evaporimeter 26 can be the water-cooled evaporimeter, also can be the air-cooled type evaporimeter.
During this equipment operation, the high-temperature high-pressure refrigerant steam that comes out from refrigeration compressor 1 enters water cooled condenser 14, and with the cooling water heat-shift, refrigerant vapour is reduced to low-temperature refrigerant steam from high temperature, also has a spot of liquid refrigerant that is converted into.Cold-producing medium enters after water cooled condenser 14 comes out the water cooled condenser 20 again, and cold-producing medium almost completely is condensed into liquid state, emits a large amount of latent heat.If higher, do not satisfy the requirement of refrigeration system duty from the refrigerant temperature that water cooled condenser 20 comes out; Just valve 28 is closed, make the low-temperature refrigerant steam that comes out from evaporimeter 26 enter the shell channel of cooler 21, the high temperature refrigerant heat-shift with in its heat exchanger tube makes its cooling.If in the time of must be to the cooling of the cold-producing medium in the heat exchanger tubes in the cooler 21, just with valve 28 unlatchings, low-temperature refrigerant is come out from evaporimeter after through valve 28, enter vapour liquid separator 29, return refrigeration compressor 1 afterwards.And the refrigerant vapour that comes out from water cooled condenser 20 through heat exchanger tubes in the cooler 21 after, enter evaporimeter 26 after entering device for drying and filtering 23 and restricting element 25 again, carburation by evaporation absorbs the heat of cooling medium (water or air), realizes air conditioner refrigerating.Meanwhile, the temperature at water cooled condenser 14 and 20 places acquisition hot water can reach 55~60 ℃ and 35~45 ℃ respectively.
The utility model is applicable to that it is main heating water, and air conditioner refrigerating is the occasion of assisting.
The cooling water pipeline that the temperature of engine 4 jacket waters can reach 80 ℃ of aiutages produces 40~80 ℃ of the hot water of higher temperature.
The utility model is owing to adopted multiple conservation measures, the used heat of discharging when liberated heat and engine 4 are worked when making full use of the refrigerant vapour condensation, therefore, can in air conditioner refrigerating, produce the hot water of higher temperature, its energy conversion rate height, comprehensive Energy Efficiency Ratio Cop can reach more than 3.5 and be suitable for using in the power tense area.
Embodiment:
As shown in the figure, refrigeration compressor is selected YF for use 1810C type Piston Refrigerant Compreessor, power adopts D234V 6H type engine h, the cooling water system of engine 4 jacket water systems and aiutage is in parallel, and oral siphon is 7, outlet pipe is 8.It is 13 and 19 in addition that water cooled condenser 14 and 20 oral siphon divide.On its outlet pipe 11 and 16, be equipped with valve 10 and 15.
In this device, the heat of about 10,000 kilocalories is emitted in the completing combustion of 1Kg diesel oil.D234 6The mechanical efficiency and the thermal efficiency of h type engine h are 40%, and when promptly burning 1Kg diesel oil, the merit that engine is done compressor is the merit that is equivalent to 4,000 kilocalories.YF 1The refrigerating capacity of 810 type refrigeration compressors is 600KW, and shaft power is 103.5KW, and refrigerating capacity nearly is 6 times of shaft power, and we tentatively get 4 times and calculate, and refrigerating capacity will be 4000 kilocalories * 4=1.6 ten thousand kilocalories.Heating capacity is more than or equal to refrigerating capacity, and promptly cooling water absorbs the heat of 1.6 ten thousand kilocalories in condenser, adds 4 kilocalories of the used heat that cooling water flow absorbs when cylinder sleeve cooling system and aiutage (air-water heat exchanger), can obtain the heat of 20,000 kilocalories altogether.In addition, add refrigerating capacity 1.6 ten thousand kilocalories of refrigeration system, can obtain energy (heat content and cold) altogether is 3.6 ten thousand kilocalories, and promptly comprehensive Energy Efficiency Ratio Cop is 3.6.Compare with lithium bromide fuel oil air-conditioning unit with oil burning boiler, its energy conversion rate is much bigger.It has energy-efficient advantage, and has the multi-functional of air conditioner refrigerating and heat supply water, is suitable for using in the area of power tense.
