Description

TECHNICAL FIELD

[0001] The utility model relates to industrial energy saving technical field, concretely relates to air conditioning box energy saving quantity calculating device. BACKGROUND

[0002] In the air conditioning process, the entering air needs to be cooled and dehumidified in the air conditioning unit, and due to the low temperature of the dehumidified air, the process or comfort requirement cannot be met, so heating is needed through electricity, steam and other ways to achieve the required supply air temperature requirement.

[0003] This process of overcooling and then heating leads to a large amount of energy waste. In order to reduce energy consumption, various forms of heat pipes (such as US patent US5845702) are used to precool and reheat the air, and the refrigeration capacity and heating capacity are saved respectively through this precooling and reheating.

[0004] In actual use, the refrigeration capacity corresponds to the power consumption of the refrigeration unit, and the heating capacity corresponds to the steam heating, or electric heating, or hot water heating and other forms. In an enterprise, usually one refrigeration unit supplies cooling to multiple air conditioning units, so if part of the air conditioning units are energy-savingly modified, it is difficult to quantitatively evaluate the power consumption of the refrigeration unit. If a calorimeter is added to the refrigeration water pipeline of each modified air conditioner, the cost of measurement will be high. Similarly, if the heating capacity is measured by adding a steam meter, an electric meter, or a hot water calorimeter, the cost will also increase, and in many cases, the cost will not be worth it. In addition, these measurement methods need to be in two states of heat pipe operation and non-operation to compare the energy-saving effect. In fact, on the one hand, the cut-off of the heat pipe energy-saving device itself has technical difficulties; on the other hand, since the air inlet temperature and humidity of the air conditioner are often related to the weather conditions at the time, even if the heat pipe can be turned off, due to the inconsistency of the air inlet state, only a rough comparison can be made.

[0005] Based on this, the utility model designs an air conditioning box energy saving quantity calculating device to solve the above problems. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical scheme in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0028] The present application will be further described below in combination with the embodiments.

[0029] In the following description, "left", "right", "front", "back", "up", "down" are oriented in the perspective view direction.

[0030] In some embodiments, as Figures 1-4As shown, an energy-saving calculation device for an air conditioning unit includes a bracket 2, a temperature sensor 3, a first sensor 4, and an anemometer 5.

[0031] The bracket 2 is fixedly installed inside the air conditioning unit 1, and the bracket 2 is located on the right side of the reheat heat exchanger 13; a temperature sensor 3 is fixedly installed on the left side of the reheat heat exchanger 13, and a first sensor 4 and an anemometer 5 are fixedly installed on the inner wall of the air outlet duct 16.

[0032] A mixed air sampling component 6 is fixedly installed on the bracket 2; the mixed air sampling component 6 includes a mixed air sampling pipe 61 and a sampling component 62. The mixed air sampling pipe 61 is installed on the bracket 2, and the sampling component 62 is installed on the bracket 2 and the mixed air sampling pipe 61; a temperature sensor 3 is fixedly installed on the sampling component 62.

[0033] In this embodiment, when the energy-saving calculation device of the air conditioning unit is working normally, fresh air enters the interior of the air conditioning unit 1. After being cooled by the pre-cooling heat exchanger 11, the fresh air passes through the surface cooler 12 for further cooling and dehumidification. Then, after being preheated by the reheat heat exchanger 13, it is heated to the required temperature by the heater 14. During this process, heat is transferred from the pre-cooling heat exchanger 11 to the reheat heat exchanger 13 through heat pipes, increasing the air temperature passing through the reheat heat exchanger 13 and decreasing the air temperature passing through the pre-cooling heat exchanger 11, thereby achieving energy saving. During this process, condensation may occur during the air pre-cooling process. Therefore, both sides of the pre-cooling heat exchanger 11 contain both sensible heat from temperature changes and latent heat from moisture content changes. The reheating process, however, is only a heating process, and the sides of the reheat heat exchanger 13 only contain sensible heat from temperature changes and latent heat from moisture content changes. The sensible heat of temperature change is used to start the sampling component. The air on the right side of the reheat heat exchanger 13 enters the mixing air sampling pipe 61 through the sampling component 62 and flows out in a concentrated manner. The temperature sensor 3 detects the temperature of the air flowing out of the mixing air sampling pipe 61 and the temperature on the left side of the reheat heat exchanger 13. The overall air volume flow rate and density are calculated by the first sensor 4 and the anemometer 5, respectively. The mass flow rate of the air is obtained by multiplying the air volume flow rate and the air density. The energy saved can be calculated by multiplying the temperature difference between the two sides of the reheat heat exchanger 13 by the temperature sensor 3, the temperature difference between the two sides of the reheat heat exchanger 13 by the temperature sensor 3, and the mass flow rate and specific heat of the air. Thus, the energy saving can be calculated in real time without shutting down the heat pipe system.

[0034] In some embodiments, such as Figures 1-4 As shown, the mixed air sampling pipe 61 includes a sampling pipe 611, branch pipes 612 and a connecting component 613. The sampling pipe 611 is fixedly installed on the bracket 2, and multiple sampling pipes 611 are fixedly connected through the connecting component 613; multiple branch pipes 612 are fixedly installed on the sampling pipe 611; the multiple sampling pipes 611 and the multiple branch pipes 612 are all connected.

[0035] The plurality of branch pipes 612 are symmetrically and uniformly distributed on the upper and lower sides of the sampling pipe 611.

[0036] The mixed air sampling pipe 61 further comprises a plug 614, and the two ends of the connected sampling pipe 611 are fixedly installed with the plug 614.

[0037] The sampling assembly 62 comprises an air inlet 621, a sampling fan 622 and an air outlet pipe two 623, a plurality of air inlets 621 are arranged on the branch pipe 612, and the air outlet pipe two 623 is fixedly installed on the middle sampling pipe 611; the sampling fan 622 is fixedly installed on the bracket 2; and the temperature sensor 3 is fixedly installed on the air outlet pipe two 623.

[0038] The air inlet of the sampling fan 622 is communicated with the sampling pipe 611 through the air outlet pipe two 623.

[0039] The plurality of air inlets 621 are equidistantly distributed on the branch pipe 612.

[0040] The first sensor 4 is a temperature and humidity sensor.

[0041] The communication assembly 613 is composed of a mounting block and a slot, one end of the sampling pipe 611 is fixedly installed with the mounting block, the mounting block is provided with a through slot, the other end of the adjacent sampling pipe 611 is inserted into the slot, and the end of the adjacent sampling pipe 611 and the slot are fixedly connected together by glue.

[0042] In the embodiment, when the mixed air sampling assembly 6 normally works, the plurality of sampling pipes 611 can be spliced through the communication assembly 613 according to the size of the windward surface of the two sides of the reheating heat exchanger 13, so that the sampling pipes 611 can be assembled according to the size of the windward surface, the collection range is increased, the collection range of the windward surface is improved, and the detection accuracy is improved; the sampling fan 622 drives air circulation, air enters through the plurality of air inlets 621 on the branch pipe 612, mixes in the sampling pipe 611, and then passes through the air outlet pipe two 623, and the temperature sensor 3 detects the temperature at the air outlet 623, so as to realize that the average temperature of a large area is calculated by one temperature sensor.
