The utility model has the advantages that refrigerating output is stored in the form of ice during night, and the recovered waste heat is used for heating water to be stored in the hot water tank, so as to achieve the purposes for not only satisfying the refrigeration or warming requirement during the day but also saving electrical power; at the same time, the refrigeration and the heating do not need equipment such as a boiler, and the like, so the device has energy conservation and no pollution and is favorable for the environmental protection; the device can fully enjoy the policy that the electric power changes is lower at night, transfers the peak power load to the night, not only balances the network load but also can reduce the running expense of equipment; and in addition, the device can improve the warming quality when the external temperature is very low in severe winter.
Description
Technical field
The utility model belongs to refrigeration, technical field of heat pumps, is specifically related to a kind of cold and hot energy storage equipment that can be used for handpiece Water Chilling Units or heat pump.
Background technology
Tradition chilled water machine or heat pump type air conditioning system are comfortablely to cool off or heat for people live purely, the subsidiary heat that produces during refrigeration, or the subsidiary cold that produces all enters atmosphere emptying when heating, and can not make full use of, and causes the waste in the energy utilization.On the other hand, be the peak period that air-conditioning uses the daytime in summer in winter, also is each business electrical peak period, this moment is Chu Now electricity shortage probably, and electric power authorities often issue bulletin for this reason, require each enterprise, particularly the large electricity consumer keeps away the peak summer and allows electricity, carries out staggered office hours; And the electricity consumption at night is in the lowest point, and electric power can not be fully utilized.
The utility model content
The purpose of this utility model is: the shortcoming that technology is arranged for Ke Fu Now, a kind of recovery waste heat and cold-storage device that is applicable to refrigeration machine or heat pump is provided, store the cold that refrigeration produces night with the form of icing, the waste heat heat hot water that reclaims is stored in the boiler, reach and both can satisfy daytime refrigeration or heating needs, the purpose of the conservation of power energy again.
For achieving the above object, the technical scheme that adopts is: a kind of recovery waste heat and Xu Leng Installed put, comprise the air conditioner loop that is interconnected to constitute successively by cold wind coil pipe, by-passing valve, pump and refrigerating/heat pump unit, it is characterized in that: described air conditioner loop also is connected with the Xu Leng Installed that the recovery Yu Re Installed that is made up of heat-exchanger pump, boiler puts and be made up of ice storage cylinder, control ice valve and puts.
Described recovery Yu Re Installed puts with refrigerating/heat pump unit pipeline and is connected.
Be equipped with control ice valve on the described air conditioner loop, in the less system of refrigerating capacity, described ice storage cylinder places the downstream of refrigerating/heat pump unit to constitute the bypass of described air conditioner loop.In the bigger system of refrigerating capacity, described ice storage cylinder places the upstream of refrigerating/heat pump unit to constitute the bypass of described air conditioner loop.
Described boiler can be an open cycle system, or the pressure-bearing closed-loop system.In the boiler heat exchanger coil can be arranged, also can not have heat exchanger coil.
Described refrigerating/heat pump unit, boiler and ice storage cylinder can be one, also can modularized design, a plurality of refrigerating/heat pump units, boiler and ice storage cylinder are linked together, to reach bigger capacity.
Described boiler and ice storage cylinder can be Any shape, as are cylindric or rectangular casing.
The utility model has the advantages that: utilize recovery waste heat and Xu Leng Installed to put, freeze simultaneously and heat, can reduce emission of carbon-dioxide, the energy-conservation pollution-free again environmental protection that helps without heating equipments such as other boilers; Can enjoy the electricity charge at the night policy low to the full, the peak power load is changeed enough in night than daytime, not only balancing power network load, but also can reduce the equipment operating cost; Can improve the heating quality when severe winter, external temperature was very low.

Fig. 3 is another structural representation of the utility model.
Among the figure, 1-cold wind coil pipe; The 2-by-passing valve; The 3-pump; The 4-heat-exchanger pump; 5-refrigerating/heat pump unit; The 6-boiler; 7-ices tube; 8-control ice valve; The 9-heat exchanger; The 10-chilled water pump.
The specific embodiment
As seen illustrated in figures 1 and 2, a kind of recovery waste heat and Xu Leng Installed put, comprise the air conditioner loop that is connected to form successively by cold wind coil pipe 1, by-passing valve 2, pump 3, refrigerating/heat pump unit 5, it is characterized in that: described air conditioner loop also is connected with the Xu Leng Installed that the recovery Yu Re Installed that is made up of heat-exchanger pump 4, boiler 6 puts and be made up of ice storage cylinder 7, control ice valve 8 and puts.
Described recovery Yu Re Installed puts with refrigerating/heat pump unit 5 and is connected by pipeline.
Fig. 1 is at refrigerating capacity hour the utility model structural representation, is equipped with control ice valve 8 on the described air conditioner loop, and described ice storage cylinder 7 places the downstream of refrigerating/heat pump unit 5 to constitute the bypass of described air conditioner loop.
When refrigerating capacity was big, described ice storage cylinder 7 placed the upstream of refrigerating/heat pump unit 5 to constitute the bypass of described air conditioner loop.
Described boiler 6 can be an open cycle system, or the pressure-bearing closed-loop system.In the boiler 6 heat exchanger coil can be arranged, also can not have heat exchanger coil.
Described refrigerating/heat pump unit 5, boiler 6 and ice storage cylinder 7 can be one, also can modularized design, a plurality of refrigerating/heat pump units 5, boiler 6 and ice storage cylinder 7 are linked together, to reach bigger capacity.
Described boiler and ice storage cylinder can be Any shape, as are cylindric or rectangular casing.
For preventing that chilled water from freezing, need in the pipeline of air conditioner loop, add ethylene glycol, during the night dip electricity price, refrigerating/heat pump unit 5 is lowered the temperature ethylene glycol, water in the ice storage cylinder 7 is stored refrigerating capacity with the form of ice, and the used heat that refrigerating/heat pump unit 5 produces is put by the surplus hot Installed that reclaims and is added hot water and be stored in the boiler 6.Heat-exchanger pump 4 circulates to improve water temperature water between refrigerating/heat pump unit 5 and boiler 6.By day during peak electricity tariff, refrigerating/heat pump unit 5 is closed, pump 3 makes the ethylene glycol solution ice storage cylinder 7 of flowing through, with the ice heat exchange in the letter, melt ice in the ice storage cylinder 7, the circulation fluid temperature is reduced, circulating fluid is through cold wind coil pipe 1 cooling in the room, and life from boiler 6, need not to use other refrigeration machine or boiler with hot water.When heating severe winter, the utility model can provide auxiliary heating.When external temperature is low, source pump can't provide enough heats to satisfy the building heating installation demand on daytime.The recovery Yu Re Installed of source pump puts, and can be released in the additional heat that store night, to replenish the needs of comfortable heating on daytime.
For avoiding sticking ethylene glycol solution flow process oversize, can be as shown in Figure 3, air conditioner loop is divided into chilled water circuit and ethylene glycol solution loop, interconnect by heat exchanger 9, chilled water pump 10 circulates chilled water in the chilled water circuit, obtain cold and send cold wind coil pipe 1 to from heat exchanger 9, Gai Installed of power consumption ， that reduces pump 3 in the ethylene glycol solution loop simultaneously put can be neatly with refrigeration unit 5 and ice storage cylinder 7 An Installed from Jian Zhu Wu More place far away.
