Technical field
The utility model is to belong to technical field of heat pumps, is specifically related to a kind of the night dip electric energy that makes full use of, the accumulator of heat supply on daytime or refrigeration and heat pump composite set.
Background technology
Heat pump is a kind of heat to be transferred to the machinery of the higher object of temperature from the lower object of temperature, and heat pump adds conversion equipment, then can be used for heating, summer winter and can be used for cooling, so extensive use in modern air conditioning engineering.The heat pump power consumption, but nearly all industrial country all the power load energy imbalance can occur: i.e. and electricity consumption shortage on daytime, night, power supply was superfluous.How to make heat pump avoid or use less the peak electricity on daytime, the electricity that makes full use of the surplus in night comes ice making or hot water, and be in store for daytime cooling or heat supply be the important topic that people study.
The utility model content
The purpose of this utility model provides a kind of night dip cheap electric energy that makes full use of, and is used for the energy storage appearance and the heat pump composite set of heat supply on daytime or refrigeration.
For reaching above-mentioned target, the technical scheme of employing is: with the cheap electric ice making of the low ebb in night and be stored in the accumulator, so that be the building cooling with molten ice mode during peak electricity tariff by day; Or heat pump heats water with the cheap electricity of the low ebb in night and is stored in the accumulator, so that heat with hot water during peak electricity tariff by day.This accumulator and heat pump composite set comprise accumulator and heat pump, it is characterized in that: described heat pump, accumulator and controller, wind coil pipe, by-passing valve, pump link to each other successively, form the loop, and described wind coil pipe and described accumulator are equipped with bypass.
In the container that the housing of described accumulator and lid are formed, be equipped with heat-exchanging tube bundle, be equipped with the import and export of import and export and described heat-exchanging tube bundle on the described housing wall.
Described accumulator is cuboid or cylindrical shape; Described heat-exchanging tube bundle is crooked spiral.
Described accumulator can be single, also can be made up of a plurality of accumulator standard module serial or parallel connections.
Good effect of the present utility model is: make full use of the cheap electric ice making of low ebb or the hot water in night, and be stored in the accumulator, be used for refrigeration or heating daytime during peak electricity tariff.Because with the cheap electricity of low ebb in night, so reduced operating cost; Adopted accumulator, needed refrigeration of heat pump or heating capacity reduce, thereby the heat-pump apparatus cost descends; Very hot the time, accumulator can be as replenishing that heat pump heats or freezes for utmost point cold-peace.

Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the utility model structural representation;
Fig. 2 is circular accumulator structural representation;
Fig. 3 is square accumulator structural representation.
Among the figure, 1,1 '-the ethylene glycol import and export; The 2-housing; The 3-lid; The 4-heat-exchanging tube bundle; 5,5 '-water entrance; 6-wind coil pipe; The 7-by-passing valve; 8-ethylene glycol fluid pump; 9-water source chiller-heat pump; The 10-accumulator; 11-accumulator shunt valve; The 12-control valve; 13-wind coil pipe shunt valve.
The specific embodiment
Fig. 1 is the utility model structural representation.Illustrate as seen: accumulator and heat pump composite set, comprise accumulator 10 and heat pump 9, it is characterized in that: described heat pump 9 links to each other with controller 12, wind coil pipe 6, by-passing valve 7, pump 8 successively with accumulator 10, forms the loop, described wind coil pipe 6 is equipped with bypass 13, and described accumulator 10 is equipped with bypass 11.
In the housing 2 and lid 3 containers of forming by Fig. 2 and the visible described accumulator 10 of Fig. 3, be equipped with heat-exchanging tube bundle 4, be equipped with on described housing 2 walls import 5 and outlet 5 ', and the import 1 of described heat-exchanging tube bundle 4 and export 1 '.Described accumulator 10 is cuboid or cylindrical shape; Described heat-exchanging tube bundle 4 is crooked spiral.
Container transportation for convenience, the size of accumulator 10 generally is not more than the standard size of container, big if desired capacity energy storage, accumulator 10 also can be made up of a plurality of accumulator standard module serial or parallel connections.
What fill in the heat-exchanging tube bundle 4 in the example is the ethylene glycol fluid, is full of water outside heat-exchanging tube bundle 4 and between the housing 2.When accumulation of heat, the high temperature glycol fluid in the heat-exchanging tube bundle 4 is heated to be hot water to the water in the accumulator 10; When cold-storage, the low temperature ethylene glycol fluid in the heat-exchanging tube bundle 4 becomes ice to the water in the accumulator 10.
During heat supply, heat pump 9 utilizes the cheap electricity of the low ebb in night with the heating of the water in the accumulator 10, and pump 8 is sent the ethylene glycol fluid into heat pump 9, and the ethylene glycol fluid raises through temperature behind the heat pump.At this moment, control valve 12 is with ethylene glycol fluid guiding accumulator heat storage container 10, high temperature glycol fluid in the heat-exchanging tube bundle 4 is heated to be hot water to the water in the accumulator 10, through control valve 12, get back to pump 8 by shunt valve 13, by-passing valve 7, this heat-accumulating process repeatedly, heated water can be used for the heating on daytime in the accumulator 10.When heating by day, heat pump can be stopped using to save the expensive electricity charge.Pump 8 is sent into the ethylene glycol fluid and through behind the out-of-operation heat pump 9, control valve 12 heats up ethylene glycol fluid guiding accumulator 10, the ethylene glycol fluid by the water heat temperature raising in the accumulator 10 after, through control valve 12, for 6 heating of wind coil pipe, get back to pump 8 by by-passing valve 7 at last.
When the required load in building exceeded the ability of accumulator 10 accumulation of heats heating, heat pump and accumulator 10 can heat simultaneously according to the workload demand in building.If night, the building also needed heat supply, heat pump can heat for the building simultaneously and be that accumulator 10 interior water heat,
During refrigeration, if the building is not when need cooling night, heat pump is at this moment as cooling-water machine, and with the water ice making in the energy-storing container, pump 8 is sent into the ethylene glycol fluid and through behind the heat pump 9, the ethylene glycol fluid temperature (F.T.) descends.At this moment, control valve 12 is with ethylene glycol fluid guiding accumulator 10, and the ethylene glycol fluid through control valve 11, is got back to pump 8 by shunt valve 13 through by-passing valve 7 after the water-setting in the accumulator 10 is build-up ice.This process of cool repeatedly, the ice in the accumulator 10 can be used for the refrigeration on daytime.Daytime, heat pump can shut down to save the expensive electricity charge, pump 8 is sent into the ethylene glycol fluid and through behind the out-of-operation heat pump 9, control valve 12 is with 10 coolings of ethylene glycol fluid guiding ice-reserving container accumulator, after the ethylene glycol fluid is lowered the temperature by the ice in the accumulator 10, through control valve 12, for wind coil pipe 6 coolings, get back to pump 8 by by-passing valve 7 at last.Equally, when the required load in building exceeded the ability of accumulator 10 ice-reserving coolings, heat pump 9 and accumulator 10 can be according to the workload demand while coolings in building.If night, the building also needed cooling, heat pump 9 can be the building cooling simultaneously and be accumulator 10 ice making ice-reservings.
The utility model is except can also being applicable to air-cooled heat pump with water cooling heat pump combines.Its operation principle is similar to above-mentioned water cooling heat pump system.
