Detailed description of the invention
The utility model provides a kind of window phase change cold-storage register in conjunction with night ventilation, is described further the utility model below in conjunction with the drawings and specific embodiments.
This apparatus structure as shown in Figure 1, comprises air filtration layer 1, phase-change material packed layer 2 and blower fan layer 3 from front to back.
Described air filtration layer 1 adopts and uses PTFE purification of air film; PTFE purification of air film has fibrillation shape microcellular structure, porosity more than 85%.Not only can reach the object purified air, simultaneously because air-filtering membrane is very thin, only have 0.01mm thick, the volume therefore needed for air filtration layer 1 is very little, can increase the space of phase-change material packed layer 2, stores more cold.
Described phase-change material packed layer 2 is made up of several vertically disposed heat exchange units, fills phase-change material in each heat exchange unit; Each heat exchange unit combination forms plate-type heat-exchange form structure.Phase-change material packed layer 2 also can adopt the version of other heat exchangers.
Phase-change material is paraffin, and using expanded perlite as carrier mass; Carrier mass first phase transition temperature is higher, in the transition temperature range of operation material, keep solid shape, next has loose structure, has suction-operated to liquid phase change material, sizing phase-change material can be formed with operation material, ensure in phase transition process, maintain original form.Simultaneously auxiliary have graphite to increase thermal conductivity factor.
In described blower fan layer, one or more axial flow blower is set.
The size of device is corresponding with the size of forms: the length of device is the length of corresponding window, the wide of device is the wide of corresponding window, device thick equals along about the half to roof distance on window, while can according to required payload, or bulk size adjusts.The crust material of device can select stainless steel material.The top of device arranges the horizontal rotating shaft of band damping, and by the wall connecting on horizontal rotating shaft and window top.
The utility model provides a specific embodiment:
Choose the long room for 5.5m, wide 4m, high 3m, the window size corresponding to device is long 1.6m, wide 0.7m, and on window, edge is 0.5m apart from the distance on roof.There are desk 7, chair 8, computer 9, door 10 in indoor.
Window phase change cold-storage register 4 adopts stainless steel material as housing, and wall thickness is 2mm; Window phase change cold-storage register 4 is long is 1.6m, wide 0.7m, high 0.3m.Phase-change material packed layer 2 is made up of 15 length of a film 0.6m, wide 0.2m, the thick heat exchange unit for 0.06m, and the gap between every two panels heat exchange unit is 0.04m.
Placement location is in a room as shown in Figure 2 when cold-storage for window phase change cold-storage register 4: during charging, window phase change cold-storage register 4 is folded into the position of the window 5 being attached at unlatching, because the wind speed perpendicular to window place is maximum, the outdoor air access to plant with maximum wind velocity can be made like this, increase heat exchange amount.In sunykatuib analysis, choosing night indoor initial temperature is 28 DEG C, and outdoor cold wind temperature is 23 DEG C.Analog result shows, and cold-storage continued after 6 hours, and device phase change material inside can reach 23 DEG C (design sketch as shown in Figure 3).
Placement location is in a room as shown in Figure 4 when releasing cold for window phase change cold-storage register 4: when releasing cold operating mode, window phase change cold-storage register 4 is raised to apart from respective distance place, roof (with close window 6 on along concordant horizontal positioned), heat exchange, by aircondition, is carried out with phase-change material in unlatching blower fan guiding indoor comparatively hot-air.In sunykatuib analysis, choosing daytime indoor temperature is 32 DEG C.Analog result shows, and adopt force ventilation, through 3 hours, indoor temperature can drop to 27 DEG C (design sketch as shown in Figure 5) from 32 DEG C.
When cold-storage, when the wind speed of window phase change cold-storage register 4 porch is greater than 1m/s, gravity-flow ventilation is utilized to carry out cold-storage.When window phase change cold-storage register 4 inlet velocity is less than 1m/s, open blower fan, adopt force ventilation, improve heat exchange amount.When releasing cold, opening blower fan, adopting force ventilation to guide room air to flow through device and carrying out heat exchange.
According to analogue data (as following table), selected phase-change material phase transition temperature can between 23 DEG C-32 DEG C, and consider that the difference of phase transition temperature and indoor temperature is larger, daytime, released cold quantity was more simultaneously.Therefore phase transition temperature is selected to be 24 DEG C.Phase transition temperature can change according to actual temperature situation and workload demand.
In described plate type heat exchanger form, the quantity of plate and deployment scenarios are determined according to actual design demand and steric requirements.
