Hereinafter, embodiments of the invention will be described with reference to the drawings.In the accompanying drawings, identical Reference numeral represents same or similar parts, or same or similar step.
Fig. 1 is the process flow diagram of the method for electric simulation of energy consumption according to single residential architecture of the present invention.First enter step 101, the information of single simulated residential architecture inner room and the information of the interior electrical equipment of building are collected and added up.
Particularly, can by understanding layout and the using function in each room to plane figure's information statistics of single residential architecture.Room information statistics according to the present invention preferably divides with room functions.Such as, room can be divided into guest room, kitchen, reception room, laundry, garage, bedroom, changing rooms, toilet etc.The statistics of the information of electrical equipment in building is also divided with electric function.Such as, classification comprises: illumination, heating and air-conditioning, elevator, plumbing equipment, household electrical appliance etc.For each electrical equipment, also need to add up its place to use, quantity and power information thereof etc.
Then enter step 102, carry out statistics and the separately statistics of life pattern and the setting thereof of single residential architecture user of service.The setting of life pattern is preferably in units of day.Because the user of service of single residential architecture is relatively fixing, work and rest custom is regular strong, and the change possibility of relative ordinary residence is little.Therefore, the user's daily life system for building needs to carry out prior statistics and modelling, to be convenient to statistical study afterwards.
Shelter personnel mainly refer to the personnel lived in for a long time in the shelter of single residential architecture.Several main life pattern of each personnel such as comprises working, goes to school, rest at weekend, rest of having a holiday, work are gone on business, family party, friend's party etc.Because the life pattern that relates to may be more thus cause the complicacy of modeling algorithm excessive, preferably, need to carry out purposive difference and classification to it.The object distinguished life pattern and sort out mainly carries out electric energy consumption analysis, for the less pattern of energy consumption suitably to other pattern merging treatment similar, to simplify computation complexity.Concrete timetable to be listed, pattern of such as going to work: between WA, the work hours, come off duty and get back to habits and customs in shelter time, night shelter, night's rest time to often kind of pattern.Wherein may have multiple habits and customs in each pattern, sampling as much as possible should often plant the data of custom for this kind of situation in the data sampling investigation phase, coordinate room to use to sum up often kind of custom corresponding use electric consumption.
To inhabitation personnel and separately life pattern statistics and after setting, enter step 103, add up the using forestland in each room in single residential architecture shelter, the personnel counted on by above-mentioned steps 101-102 and electrical equipment information table are shown as one or more using forestland into each room.By understanding personnel's work and rest and Equipments Setting in shelter, can be very clear and definite by shelter the operate power of roomed consumer and connecting their respective service time, and after both link together, what can obtain the various equipment in each each moment of room uses electric energy consumption.
Following table is an exemplary room using forestland statistics:
Table 1 room using forestland statistics
The analysis of step 103 is all the electricity consumption energy consumption statistic carried out based on the various electrical equipments in each room in building.According to the present invention, the simulation of electricity consumption statistics is accounted for the ratio of the total energy consumption of single residential architecture according to its energy consumption, be divided into season power load and other residential electricity consumption loads carry out analog computation respectively.Season, power load has larger indoor temperature adjustment electric energy consumption, i.e. heating, refrigeration, ventilation electricity consumption in summer or winter; Other residential electricity consumption loads are other residential electricity consumptions whole in single residential architecture except season power load, are divided into the load relevant with human behavior, daily electric load and basic power load.
In step 104, for comprise heating, refrigeration, ventilation electricity consumption season load power consumption carry out simulation of energy consumption analysis day by day.Existing simulation of energy consumption method can be adopted to simulate, such as Cooling and Heat Source power consumption adopt DEST simulation of energy consumption software carry out load in season by time analyze.Following table schematically list 2 exemplary season load energy consumption statistic table.
Table 2.1 shelter typical case in summer day seaonal load table
Table 2.2 shelter typical case in winter day seaonal load table
In step 105, according to the present invention, be designed to add up in the mode of " typical case's day " to the energy consumption statistic of other residential electricity consumption loads, setting typical case's day.According to one embodiment of present invention, single residential architecture can be set as the statistics of following five typical days, and five typical days comprise: normal working typical case's day, normal typical case's day weekend, guest's weekend (reception) typical case's day, work typical case's day of going on business, typical case's day weekend of going on business.
Then, in step 106, by other residential electricity consumption load classification and based on typical case carry out day by time load statistical study.According to one embodiment of present invention, other residential electricity consumption loads mainly can be divided into three major types: with human behavior involved loads, daily electric load and basic power load.Refer to that the use that the activity of personnel in shelter directly causes some consumers comprises with human behavior involved loads: electric consumption on lighting, cooking electricity consumption, general socket electricity consumption.The setting of daily electric load will occur by during personnel activity in single shelter, but cannot determine a type load of electricity consumption time of origin.It mainly comprises: the light socket electricity consumption of laundry machine room, corridor, toilet; The electric consumption on lighting of storeroom, equipment room, courtyard landscape design; The power consumption of the equipment such as pressurizing feedwater, draining, elevator existed in larger single residential architecture.Basis power load is the power load that all must occur every day, and the electricity consumption of this type load continues to occur, and its consumer comprised comprises: life refrigerator, the small-sized building control main frame that household equipment controls, shelter safety monitoring electricity consumption etc.
According to one embodiment of present invention, when estimating with human behavior involved loads, in typical case's day simulated data, power consumption data hourly extract cumulative obtaining according to shelter personnel amount, state, activity from room using forestland table.Such as can take as under type with the statistical method of the three major types power consumption of human behavior involved loads: shelter lighting load is according to 7W/m
2calculate, concrete power consumption is determined according to resident family's mechanics; Kitchen load is by hour 2kW that often eats, and all the other calculate according to 0.5kW; Jack device standby power consumption carries 50w estimation by normal, and all the other press power calculation between prefabricated house.
When estimating daily load power consumption, considering not timing working equipment (as elevator), not timing perform region (as laundry machine room, corridor, toilet), estimating the working time of its average every day, count daily load.In addition, because this type load is difficult to the electricity consumption quantity being accurate to each hour, but their time of origin all concentrates in the time except shelter personnel have a rest, therefore the total power consumption of load daily in shelter is on average had in 17 hours of personnel activity to shelter, just obtain often kind of electric energy consumption of daily load hourly of typical day.
When estimating basic load, the power consumption of such as refrigerator electricity consumption, the electricity consumption of security protection building control computer, domestic electric appliance electric leakage.The human behavior of these loads and shelter is substantially irrelevant, and no matter in shelter, whether personnel are in shelter, and these power consumption loads all can occur.In these loads, need the electric leakage of computing equipment to add up, can obtain in conjunction with number of devices in shelter with reference to the existing electric leakage parameter about household appliances enterprise.
Following table schematically list 2 exemplary typical cases Japan-China by time Estimation of energy consumption.
Table 3.1 typical case day " normal day of duty " the energy consuming part period by time estimate
Energy consuming part period of table 3.2 typical case day " guest week doomsday " by time estimate
In step 107, the hourly load statistics of typical case's day is revised.Such as, can revise in the mode of adding up exemplary operation week.Particularly, typical day Data classification step 106 simulated is added up.Except step 106 according to several type loads required in simulation of energy consumption method with typical case day form express except, also need to integrate according to the rule of life of user.Such as+2 normal doomsdays in week of 5 normal days of duty constitute exemplary operation weeks maximum in the middle of 1 year.Add 5 normal days of duty+1 in normal week doomsday+1 guest according to then there being (such as monthly) of frequency in the reception requirement simulation process that owner proposes and receive the doomsday in week.Again such as, be adapt to the working condition that shelter occupant often goes on business, the situation on go on business 5 working days+2 of going on business can be provided with by second week in every month on doomsday in week.
Step 108, the load load of energy consumption day by day of other residential electricity consumptions that energy consumption data and step 105-107 calculate day by day in season step 104 calculated merges, and obtains the analysis result day by day of the total energy consumption of monomer residential architecture.
Step 109, adds up day by day to the generated energy of regenerative resource.The object of the invention is by the accurate energy consumption analysis of single residential architecture and estimation, thus optionally add renewable energy technologies, neutralize the basic load of building self and daily load, the power consumption reducing shelter on the one hand reduces living cost, on the other hand when urban electric power is in short supply, the basic living energy consumption of family can be maintained by renewable energy technologies.
Renewable energy utilization technology comprises: biomass energy, wind energy, sun power.The present invention preferably selects solar electrical energy generation to provide electric energy.When adding sun power in single residential architecture, the theoretical generated energy of photovoltaic can be calculated by roof area and local radiometric analysis, and by after checking with empirical data, count daily generation.When using other regenerative resources, the generated energy of regenerative resource can calculate with reference to correlation formula.
In step 110, by consuming energy day by day, analysis and daily generation compare, and whether meet standard with what judge single residential architecture with energy, if so, then this method terminates; If do not meet, then can take multiple counter-measure.Described standard is such as green building assessment standard.The measure taked comprises step 111, improve shelter enclosed structure or use high-efficiency air-condition equipment thus reduce load energy consumption in season, such as, increase the wall thermal insulating thickness of single residential architecture, then return step 104 and recalculate season load energy consumption and analyze day by day; Step 112, is supplemented with energy by the generated energy increasing regenerative resource, then returns the daily generation that step 109 recalculates regenerative resource; And step 113, low power design is carried out to electrical equipment in shelter, thus reduces the energy consumption of other residential electricity consumptions, then return the load energy consumption that step 105 recalculates other residential electricity consumptions and analyze day by day.Low energy consumption electrical design such as can, by using energy-conserving light source, use intelligent lighting controls to reduce the load of shelter illumination section, replaces energy-saving whole kitchen equipment and reduces by electric energy consumption etc.It will be appreciated by persons skilled in the art that above-mentioned steps 111,112 and 113 can optional one or combinationally use.
In addition, it will be understood by those skilled in the art that, the load energy consumption analysis in season of above-mentioned steps 104, other residential electricity consumptions of above-mentioned steps 105-107 are analyzed, and the order of the calculating regenerative resource daily generation of above-mentioned steps 109 can be put upside down arbitrarily or exchange, above-mentioned three steps also can be carried out simultaneously.
