Description
Technical field
The present invention relates to a kind of charge system, is specifically that a kind of low cost one drags machine Split Charging system in more central air-conditioning
System.
Background technology
With economic development, central air-conditioning, particularly water system central air-conditioning is widely used in office building, commercial center
Etc. large-scale place.
Central air conditioning water system has the advantages that humiture is comfortable, the temperature difference is small, suitable for people of all ages.
Central air conditioning water system is by outdoor host computer, pipeline, circulating pump, fan coil and common group of other control devices
Into, host is the core of whole system, and cooling and warming is realized using refrigerant Transformation Principle, the hot and cold water of generation by pipeline,
Under the action of circulating pump, into each fan coil end and room air carry out it is cold and hot exchange, realize air adjustment.
With the development of Large Central Air Conditioning System, there is small-sized residential central air- water system, it is small compared to Large-scale machine set
Type residential central air- is also to drag more structures using one, and simply cooling area is opposite diminishes, simple in structure.
It is to drag more structures using one, a host can be more according to the system structure feature of central air conditioning water system
Platform indoor unit cold and heat supply, can effectively improve the utilization rate of equipment, reduce the installation cost of unit area, therefore central air-conditioning
Water system has the features such as usable floor area is big, and refrigerating capacity is big, and unit power consumption is big with respect to split-type air conditioner.Therefore, in large scale business
The non-same public place using main body such as the heart, office building, will produce the charging problem of central air-conditioning cost of use.
At present, there are the charging method of many central air-conditioning on the market.
Electricity metering type Charging System of Central Air Conditioning method：
Charging principle：Electricity metering type is exactly the power consumption by measuring air conditioning terminal, is scaled further according to power consumption cold
Amount, counts the general refrigeration ability of each user in central air conditioner system, carrys out share the expenses further according to the cold ratio of each user.
Advantage：Electrical parameter easily measures, and management accounting is easy.
Shortcoming：Chilled-water flow is not accounted for, cold, the change of temperature, does not account for fan coil type, departs from " whose
Paid using whom, with it is how many hand over how much " principle, make client there is no energy saving wish.
Time type Charging System of Central Air Conditioning method：
Charging principle：The power supply of the three speed switch of fan coil, electric two-way valve is all accessed into collector, collector is being examined
Measure two-port valve and wind velocity signal data and upload computer supervisory control system and analyzed and processed, by each range state time cumulation,
Fiducial time is converted into by given time type coefficient, according to the price appraised and decided, carries out charging.
Advantage：Time parameter easily measures, and management accounting is easy, periodically or in real time can carry out various operations to terminal.
Shortcoming：Chilled-water flow is not accounted for, cold, the change of temperature, " who is paid using whom, more with how many friendships for disengaging
It is few " principle, make client there is no energy saving wish.
Area-type Charging System of Central Air Conditioning method：
Charging principle：Central air conditioner system charging is less paid attention to energy saving, in design of air conditioning with not examined in construction
Consider practical service environment, when charge uses " lhare by area ", simply shares central air conditioner main machine with usable floor area（Including
Water pump, huyashi-chuuka (cold chinese-style noodles) product divide type but tower etc.）Expense.
Advantage：Area parameters are easily measured, and management accounting is easy.
Shortcoming：The difference of the unit area cold of different operating time is not accounted for.The unit plane in different operating place
The difference of product cold, indirect charging method depart from " who is paid using whom, with how many friendships how much " principle, make client not energy saving
Wish.
Chilled-water flow type Charging System of Central Air Conditioning method：
Charging principle：Meter flow table transmits a signal to acquisition terminal by sensor, and system is counted after receiving signal
Number and processing, and result is stored.
Advantage：The change of metering water flow overcomes time type charging deficiency again.Can timing or the terminal to having under its command in real time
Carry out various operations.
Shortcoming：Ignore the change of water temperature.Cold cannot accurately be calculated." who is paid using whom, more with how many friendships for disengaging
It is few " principle, make client there is no energy saving wish.
Precision energy type Charging System of Central Air Conditioning method：
Charging principle：The temperature sensors of high precision of one pairing is respectively being installed into water return pipeline, and on water return pipeline
One electromagnetic flowmeter is installed.The size of the chilled-water flow flowed through with flowmeter metering, is calculated with the temperature difference of water inlet, backwater
The loss of energy, while temperature signal and flow signal are accessed into energy integrating instrument.Monitoring system is carried out according to energy integrating instrument
Accurate directly charging method precision energy type charging.
Advantage：Calculated precisely by the instantaneous variation of flow, temperature, mode is transparent, it is easier to received by user, realized
" who is paid using whom, with it is how many hand over how much " principle.
Shortcoming：But system complex equipment cost is high, the anti-tampering technique of sensor is left to be desired.
Central Air Conditioning Billing System occurs a variety of different charging methods with the extensive use of central air-conditioning, respectively
Kind method can solve charging problem to a certain extent but there is each unreasonable place.The charging system of central air-conditioning
System needs to meet that charging scientific in principle is reasonable, and precision is high, and system structure is uncomplicated, and whole system cost is low, and charging effect can obtain
To customer satisfaction system necessary condition.
Electricity metering type：It is converted into cold size according to power consumption size, is then allocated further according to cold ratio
Electricity, process complexity precision are low.
Time measurement type：Changed according to the size of user's usage time, charging is carried out using the time, although method is simple
Single but precision is low, not science.
Area metering type：Calculating charge is carried out according to the usable floor area of user, is a kind of relatively backward metering method, is used
Multi-purpose to lack all, unrelated with system service condition, user does not approve.
Chilled-water flow type：Calculated according to the uninterrupted of the chilled water into access customer, similar water meter is the same, does not have
COMPREHENSIVE CALCULATING is carried out with reference to the temperature validity of chilled water, it is unreasonable.
Precision energy type：According to COMPREHENSIVE CALCULATINGs such as temperature and flows, precision is high, but whole system is complicated, of high cost, surely
Qualitative difference.
In conclusion there are various unreasonable, unscientific situations for existing Central Air Conditioning Billing System.
