Description

The energy consumption household cost allocation system of multi-joint machine central air conditioner system

Technical field

The utility model relates to the air conditioning charging field, specifically is a kind of energy consumption household cost allocation system of multi-joint machine central air conditioner system.

Background technology

The Central Air Conditioner Used in Buildings charging problem is the difficult problem of numerous infrastructure management companies always, how reasonably to measure and to collect the cost of use of centralized air-conditioning, has been the problem that numerous infrastructure management companies can not be ignored.As area methodology, water measurement Law, electric measurement Law, time measurement etc., all there are relative merits separately in the charge method that exists at present, causes the rate dispute between user and the owner easily.Now be described below with regard to current various charge methods:

1) area methodology

Bear central air conditioner operation total expenses according to user's usable floor area ratio, the instrument that needs is minimum, but can form " with many with few samples, use with need not a sample " using on the idea, cause the rate dispute between user and the owner easily, also can cause very big energy dissipation.

2) water metering

The water metering is charged as air-conditioning consumption foundation by water meter measurement user air conditioning terminal water consumption.Water meter is installed on the return pipe, and the discharge of recording user air-conditioning is chargeed according to meter reading.This method only relies on circulating water flow as expenses standard simply, does not consider the variation of recirculated water out temperature, so there is error in this method.

3) electricity metering

The ammeter charging is to charge as air-conditioning consumption foundation by the power consumption of ammeter metering user air conditioning terminal.Even do not move and will begin to charge yet as long as indoor set is opened outdoor main frame.This method has only been measured the power consumption of indoor set, and the power consumption of outdoor main frame can not measure.

4) time type metering system

Collector is connected with three speed switch on the fan coil temperature controller, obtains electric two-way valve and open signal, obtain the low-medium-high level information that the user uses simultaneously, and can add up the working time of each gear automatically.By communicator signal is reached the air conditioning charging instrument, data base administration is carried out in air conditioning charging instrument and central workstation communication.The equivalent time that uses with the user is foundation, charges.

5) energy type metering system

Native system is made up of equipment such as energy integral instrument, flowmeter, temperature sensor, communicator, air conditioning charging instrument, central workstation.The energy type household metering system the user for each one of mounting temperature sensor on the return pipe, one of flow sensor is installed on water supply line, three road signals are inserted the energy integral instrument.Measure in real time by supply water temperature, return water temperature and instantaneous delivery, and obtain the energy value that the user consumes to using cold or heat to accumulate according to thermodynamics energy computing formula to the user.Data base administration is carried out in energy integral instrument and central workstation communication.The energy value that uses with the user serves as according to charging.

More than several metering methods be applicable to that mainly the household metering and the measuring cost of water machine system are higher, and the metering of multi-joint machine system is still only limited to electricity metering and area methodology, because the defective that these two kinds of methods self exist, make multi-joint machine system household metering data have error, cause the dispute between user and owner easily.
