Technical Field

[0001] The invention relates to the field of heat pump heating systems, and in particular to an electricity fee sharing method for heat pump heating systems based on equivalent area temperature. Background Art

[0002] Traditional heat pump heating systems, whether water source heat pumps or air source heat pumps, whether fan coil heating, radiator heating or floor radiation heating, all have the problem of difficult heating metering. The method of directly measuring heating heat consumption by heat meter is theoretically feasible, but in actual work, it has the disadvantages of complex system, heat meter being greatly affected by water quality, and high cost. At the same time, due to the transfer characteristics of heat, for metering units on different floors and different locations, the same use area and maintaining the same indoor temperature, the heat consumed is different, which also causes the unfairness of heat meter measurement. For public buildings, due to the complex use functions and more changes in floor plan layout, unlike residential buildings with single functions and more regular floor plan layout, it is more difficult to measure heating heat by heat meter.

[0003] For heat pump heating systems, due to the above reasons, the heating heat cannot be accurately measured, resulting in the inability to measure the power consumption of the heating system. It is difficult for users to know their actual heating power consumption, and it is difficult to mobilize users' self-energy conservation awareness, resulting in some users' indoor temperature setting values ​​being too high, resulting in serious energy waste, while other disadvantageous users' indoor temperatures may not meet the requirements. In order to solve this problem, the present invention proposes a heat pump heating system electricity cost sharing method based on equivalent area temperature. Summary of the invention

[0004] The present invention provides a method for allocating electricity costs for a heat pump heating system based on equivalent area temperature. The method allocates the heating power consumption based on the equivalent area temperature, and takes the arithmetic mean of multiple indoor temperatures in a metering unit and the heating area as the basis for allocation.

[0014] Furthermore, in step S2, a real temperature range of a°C to b°C is set. If the indoor temperature collected at the hth moment is not within the real temperature range, the indoor temperature at the h-1th moment is used instead of the indoor temperature at the hth moment for calculation.

[0015] Furthermore, in step S2, the minimum allowable temperature is set to c°C. If the average indoor temperature of the i-th metering unit at the h-th moment is If the indoor average temperature of the i-th metering unit at the h-th moment is lower than the minimum allowable temperature, The indoor temperature accumulation value of the heating season of the i-th metering unit is not included. middle.

[0028] Step 1. Install a temperature sensor with network data remote transmission function on the air conditioning and heating terminal device;

[0029] Step 2. Divide the heating season into S time periods, record the initial collection time of the temperature sensor in the Hth time period as h, where H=1, 2, ..., S, divide the heating building into n metering units, divide each metering unit into m heating areas, install one temperature sensor in each heating area, and the temperature sensor regularly collects the indoor temperature of the jth heating area in the i-th metering unit at the hth moment , where i=1, 2, ..., n, j=1, 2, ..., m, n, m are positive integers, and the indoor temperature of the m heating areas in the i-th metering unit is arithmetic averaged to obtain the indoor average temperature of the i-th metering unit at the h-th moment , the average indoor temperature at the initial collection time of each time period in the heating season Perform cumulative calculation to obtain the cumulative value of indoor temperature in the heating season of the i-th metering unit ;

[0030] Step 3. Use the formula , the cumulative value of the indoor temperature of the i-th metering unit throughout the heating season and the heating area of ​​the ith metering unit Multiply them to get the equivalent area temperature of the i-th metering unit in the heating season , accumulate the equivalent area temperatures of all metering units during the heating season to obtain the sum of the equivalent area temperatures of all n metering units during the heating season;

[0031] Step 4. Measure the power consumption of the heat pump heating system during the entire heating season;

[0032] Step 5. Calculate the power consumption per unit equivalent area temperature , the formula is expressed as ,in, is the power consumption of the heat pump heating system during the entire heating season, The sum of the equivalent area temperatures of all n metering units during the heating season;

[0033] Step 6. Use the formula Calculate the power consumption of the heating season for the i-th metering unit ,in Represents a multiplication operation.

[0034] Specifically, the air conditioning and heating terminal device in step one includes a fan coil unit, a multi-split indoor unit and a floor heating temperature control panel.

[0035] Specifically, in step 2, the real temperature range a°C to b°C is set. If the indoor temperature collected at the hth moment is not within the real temperature range, the indoor temperature at the h-1th moment is used instead of the indoor temperature at the hth moment for calculation.

[0036] Specifically, in step 2, the minimum allowable temperature is set to c°C. If the average indoor temperature of the i-th metering unit at the h-th moment is If the indoor average temperature of the i-th metering unit at the h-th moment is lower than the minimum allowable temperature, The indoor temperature accumulation value of the heating season of the i-th metering unit is not included. middle.

[0037] Example 2

[0038] In this embodiment, an office drawing building has a heating construction area of ​​30,000 m2 and four floors above ground. According to the independent metering requirements of the building, it is divided into a maximum of 1,200 m2 and a minimum of 50 m2, with a total of 51 heating metering units. Each metering unit adopts one or two of the following heating methods: fan coil units, multi-split indoor units, and floor radiation heating, and an air source heat pump unit is used as the heating heat source.

[0039] In this embodiment, Figure 2 This is a heating plan for one of the floors of an office building. In the figure, 1 is a multi-split indoor unit with a temperature sensor that can transmit data remotely, and 2 is floor radiation heating. The floor plan consists of 4 metering units, and the heating areas are: 745㎡, 237㎡, 760㎡, and 790㎡ respectively. In summer, multi-split cooling is used, and each indoor unit has its own temperature sensor with data remote transmission function; in winter, floor radiation heating is used, and the heat source of floor radiation heating is an air source heat pump unit.

[0040] In this embodiment, the original heating fee collection method is to charge according to the heating area, and the charging standard is 39.8 yuan / ㎡. At the same time, affected by factors such as orientation and external obstruction, the indoor temperature of the western rooms of metering unit-1 and metering unit-3 is relatively low, and the severe cold weather in winter cannot reach the design requirement of 18°C, and the comfort of personnel is poor; while the indoor temperature of the south-facing room of metering unit-4 is relatively high. Since the fee is charged according to the area, the energy-saving awareness of the personnel is poor, and they do not actively adjust the temperature. Sometimes they even open the windows to dissipate heat, resulting in serious energy waste.

[0041] In this embodiment, the entire building is billed and transformed according to a heat pump system electricity cost sharing method based on equivalent area temperature of the present invention. First, each indoor unit (serial number 1 in the figure) is equipped with a temperature sensor that can transmit data remotely. Each indoor unit is responsible for a heating area. The upper computer collects the temperature of the area regularly through the network system, performs arithmetic average calculation on the collected temperatures of all heating areas in the metering unit, and accumulates the average indoor temperature collected in each time period of the heating season to obtain the cumulative value of the indoor temperature of the metering unit in the heating season, and then multiplies it by the corresponding heating area as the basis for the power consumption sharing of the heat pump host of the metering unit. According to the actual metering statistics of the 2023-2024 heating season, the heating cost of the entire building is 25 yuan / square meter, which saves 37.2% compared with the area-based charging. Among them, due to the low indoor temperature of metering unit 1 and metering unit 3, the heating cost is 22 yuan / ㎡, and the indoor temperature of metering unit 4 is high, which is 26 yuan / ㎡. The overheating condition of metering unit 4 is greatly reduced compared with the use of the present invention, and the purpose of energy saving is achieved.

[0042] Although the above describes the specific implementation mode of the invention in conjunction with the drawings, it is not intended to limit the scope of protection of the invention. Based on the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
