Description

 TECHNICAL FIELD [0001] The present invention relates to a bidirectional calorimeter, a heat energy supply system having the same, and a method of operating the same. [0002] Duplex calorimeter,

The present invention relates to a bidirectional calorimeter, a thermal energy supply system having the same, and a method of operating the same. More specifically, the present invention relates to a bidirectional calorimeter, And a heat energy supply system having the same.

The hot water factor required in a building or apartment house can be divided into district heating, central heating, and individual heating to provide heating and hot water supply. District heating means that a company with a large scale heat-generating or heat-only facility in a high-density region supplies hot water or steam to a machine room of a building or apartment building using a heat-transporting pipe represented by the primary, It refers to the heat supply method that is distributed to consumers. Central heating is a small-scale heat supply system in which a machine room of a building or a multi-family house owns a heat production facility and directly generates heat and distributes the heat to each heat consumer. In the case of this type of heat supply system, it is essential to have an integrated calorimeter for measuring the amount of thermal energy used in each customer.

Conventional district heating or central heating system is a type of this thermal energy network system. One or more heat energy supply side is defined as a system that supplies heat energy by connecting one or more heat energy demand side and piping for transporting heat medium. Can be,

The conventional concept of heat energy network system is a unidirectional heat supply system that supplies heat energy to the demand side on the supply side. Specifically, when a high-temperature heat medium is supplied from the supply side to the demand side, heat energy is obtained from the high-temperature heat medium on the demand side. The heat energy is supplied to the demand side, and the low-temperature heat medium is returned to the supply side.

On the other hand, in recent years, a bidirectional heat-exchange based heat energy network system has been developed in addition to a unidirectional heat supply system that supplies heat energy to the demand side on the supply side.

In the bidirectional heat trading system, the thermal energy supply side supplies thermal energy to the demand side and the supply side supplies and sells thermal energy to the supply side when the surplus thermal energy is generated from the demand side.

This bidirectional heat transaction can be made between the supply side and the demand side as well as between different demand side.

Therefore, it is necessary to accurately measure the amount of heat generated between the supply side and the demand side during the heat transaction. Conventionally, an integrated calorimeter optimized for unidirectional calorimetry from the supply side to the demand side has been used.

The integrated calorimeter is divided into a flow meter system for integrating only the flow rate or a calorimeter system for integrating the flow rate with the heat difference by adding a temperature difference. More specifically, the flow meter system is composed of two parts, a flow measurement unit and an operation unit, and the calorimetric system consists of three parts: a flow measurement unit, a temperature measurement unit, and a calculation unit. Generally, the integrated calorimeter is installed on the return side of the heat transfer pipe to measure the flow rate and the return temperature, and the supply temperature is measured by connecting a separate temperature sensor to the supply side.

In both methods, there are various methods of measuring the flow rate. However, a method in which the impeller is rotated in one direction by impinging the impeller through the nozzle, and the flow rate of the permanent magnet attached to the impeller is measured while the flow rate is being measured. In the past, the rotational force of the permanent magnet attached to the impeller of the flow chamber rotates the permanent magnet of the mechanical gear of the computing unit, and the number of rotations of the intermediate gear with the permanent magnet attached thereto, In recent years, however, this type of method has been escaped. In order to measure the electronic flow rate, electric power is generated by the pickup coil of the permanent magnet attached to the impeller, and the flow rate is converted Or when the permanent magnet attached to the impeller rotates, the flow rate is measured by detecting the change in the magnetic line of force between the N pole and the S pole. Here, the calorimetric method further includes a temperature measuring unit, and the measured value of the difference between the heating medium supply temperature and the heating medium return temperature is further multiplied by the flow rate to accurately measure the heating calorie.

In order to optimize the integrated calorimeter up to now, the inlet nozzle position and the flow structure of the flow measuring part have been designed and manufactured to be optimized for unidirectional heat supply. However, the present invention proposes a flow chamber structure of a bidirectional calorimeter which can be optimized for bidirectional heat supply.

In the prior art, a thermal energy network system capable of providing the supply side or the other demand side with the thermal energy produced on the supply side or the surplus thermal energy produced on the demand side is still in a state of insufficient development of the technology. In addition, the heat energy network system according to the related art has a problem that it can measure the flow rate of heat energy generated in the heat transaction only with respect to the one-directional flow, and can not be measured with respect to both directions. This is because of the flow measurement structure of the impeller calorimeter.

Therefore, when a conventional calorimeter is used in order to solve the above problems, the correction values for the two directions must be set differently, so that there are many portions to be calibrated for each calorimeter, and a difference in correction values And the increase in the error of the measurement by direction is considered. In order to prevent such problems, a separate calorimeter must be installed for each direction. However, in addition to the problem that the number of calorimeters or the number of calibrations and the amount of data in the remote meter reading increase, There is another problem such as an increase in the number.

Referring to these drawings, the operating method (S100) according to the present embodiment is characterized in that the temperature measuring unit S1 is mounted on the supply pipe SL1 of the individual generation 210 and the supply pipe (S110) in which the temperature measuring unit (S2) is mounted on the bidirectional calorimeter (SL2) and the temperature measuring unit (R3) is mounted on the bidirectional calorimeter (100).

The operating method S100 according to the present embodiment may include a temperature data detecting step S120 for detecting temperature data from the temperature measuring units S1, S2, and R3. At this time, the temperature data detection step (S120) may be executed every predetermined time.

The operating method S100 according to the present embodiment is a method in which the temperature data value of each of the temperature measuring units S1, S2 and R3 is expressed by the expression (T _{S1 -} T _R3 )> (T _{S2 -} T _R3 ) If it is determined that the individual generation 210 determines that the individual generation 210 sells thermal energy to the central thermal power supply 220 and the temperature data value satisfies the expression of (T _{S1 -} T _R3 ) <(T _{S2 -} T _R3 ) (S 130) in which it is determined that the central heating unit 220 sells the thermal energy to the individual generation 210.

The above-mentioned T _S1 value means the temperature value detected from the temperature measuring part mounted on the supply pipe of the individual generation and the T _S2 value means the temperature value detected from the temperature measuring part mounted on the supply pipe of the central heat supplying part . Further, the value of T _R3 means the temperature value detected from the temperature measuring unit mounted on the bidirectional calorimeter.

15, when the individual generation 210 sells the thermal energy to the central thermal supply unit 220, the temperature data values of the temperature measurement units S1, S2 and R3 become '( T _{S1 -} T _R3 )> (T _{S2 -} T _R3 ) '.

In this case, after determining that the individual generation 210 sells thermal energy to the central thermal supply unit 220, the heat quantity can be calculated based on the resultant value of the temperature data value T _S1 -T _R3 . At this time, the calorie calculation step S140 may calculate the calorie based on the predetermined time value.

On the other hand, as shown in FIG. 16, when the thermal energy is sold to the central heat radiating part 220, the temperature data value satisfies the expression (T _{S1 -} T _R3 ) <(T _{S2 -} T _R3 ) .

In this case, after determining that the central heat exchanger 220 sells thermal energy to the individual generation 210, the calorie can be calculated based on the resultant value of the temperature data value (T _{S2 -} T _R3 ). At this time, the calorie calculation step S140 may calculate the calorie based on the predetermined time value.
