Abstract
The invention relates to a method of calculating the use percentage of central air conditioner of each user and is applied to a central air conditioner device. The central air conditioner device is an indoor ventilator connecting each user and is defined with a refrigeration/heating percent ratio parameter VW and a rated refrigeration/heating ability ratio parameter W unit. When started, the indoor ventilator senses a temperature difference delta T between the outlet of indoor ventilator and the room and multiply VW, W unit, delta T and the ventilator working time t to obtain a unit central air conditioner consumption of a single user Q. Therefore, the use percentage of central air conditioner of each user can be obtained according to the unit consumption Q so as to be used as the fair pricing criteria to charging each user. The invention can precisely obtain the use percentage of central air conditioner of each user; hence, the fee each user needs to pay can be calculated fairly. The invention has the advantages of a better measuring accuracy and saving efficient cost.
Description
Technical field
The present invention relates to a kind of computational methods, particularly relate to a kind of method of calculating each user's central air-conditioning usage ratio.
Background technology
Along with socioeconomic prosperity and development, stand in great numbers in the city of today commercial building in the street, a plurality of company units are arranged in these commercial buildings usually, and numerous staff is assembled in whole the inner meeting in building, if do not open air-conditioning, as long as the utmost point short time promptly can make air quality become very abominable; If right each room all is equiped with an aircondition independently, and is except that mounting cost is huge, also very considerable for the consumption of electric energy.
Therefore most commercial building all uses central air conditioning plant, with cold air is example, this central air conditioning plant is made cooling water and cooling water is delivered to each company unit, after air-conditioning is opened by a unit, the pressure fan of this unit is that entry into service makes circulation of air, air is blown into indoor behind cooling water temperature, promptly becomes so-called cold air.
The early stage method of calculating the central air-conditioning usage ratio of each company unit, be that floor space number according to each company unit is that benchmark calculates required contribution quota, only the shortcoming of this kind computational methods is that the bigger unit of floor space number may not need stronger air-conditioning, and the less company unit of floor space number also may use stronger air-conditioning, and therefore list is real very fair with the central air-conditioning usage ratio that the floor space number calculates each company unit.
For solving above-mentioned unfair shortcoming with the required central air-conditioning expense of sharing of floor space number calculating, industrial circle has following three kinds of account forms at present:
1. according to law of conservation of energy, energy variation amount according to cooling water is calculated, it is the pressure fan place that is located at each company unit with a calculation element, obtain cooling water flow through the moment of this calculation element flow with the temperature difference of cooling before and after the air, can clearly calculate the actual energy variable quantity of cooling water.
2. the pressure fan of each company unit starts the coolant-temperature gage of going into that the back measures pressure fan place cooling water, and the temperature of water to be cooled picks up counting when reaching a setting value, and the thermal power of cooperation pressure fan running is used the ratio of central air-conditioning in the hope of each company unit.
3. when the water valve of opening cooling water makes cooling water flow into pressure fan, promptly calculate the pressure fan power consumption of each company unit, with usage ratio as central air-conditioning.Only the aforementioned calculation method all has its shortcoming:
Though method 1 has charging justice and advantage of reasonable, only because method 1 needs the multiple parameter of metering, and in order to improve the required precision of the measurement temperature difference, needed thermometric instruments also must be comparatively accurate, so generally speaking, the cost of method 1 is too high, still is difficult to popularizing on the market;
Method 2 then has lower-cost advantage compared to method 1, and only cost is lower, the degree of accuracy is just made a discount naturally, and when cooling water does not reach desired temperature as yet, consumes though energy is existing, but not in the computer capacity of usage ratio, more can produce inequitable problem of chargeing;
The cost of method 3 is between method 1 and method 2, but the power consumption of indoor blower motor does not have the variation situation that way is grasped indoor load really, still can produce inequitable problem of chargeing.
This shows that the computational methods of above-mentioned existing central air-conditioning usage ratio obviously still have inconvenience and defective, and demand urgently further being improved in method and use.In order to solve the problem of above-mentioned existence, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and conventional method does not have appropriate method to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.Therefore how to found the method for a kind of new each user's of calculating central air-conditioning usage ratio, real one of the current important research and development problem that belongs to, also becoming the current industry utmost point needs improved target.
Because the defective that the computational methods of above-mentioned existing central air-conditioning usage ratio exist, the inventor is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge, and the utilization of cooperation scientific principle, actively studied innovation, method in the hope of the central air-conditioning usage ratio of founding a kind of new each user of calculating, can improve the method for general existing each user's of calculating central air-conditioning usage ratio, make it have more practicality.Through constantly research, design, and after studying repeatedly and improving, create the present invention who has practical value finally.
