Description

A water module structure with electric heating tank

technical field

The utility model relates to a heating control device, in particular to an improved structure of a water module in which a high-efficiency tank heat exchanger is matched with an electric heating tank.

Background technique

With the enhancement of the society and the government's awareness of environmental protection, the disadvantages of the traditional boiler central heating in the north are becoming more and more obvious, and the waste of energy consumption is relatively large, so it is urgent to replace it with an environmentally friendly heating method. In recent years, heat pump heaters have also become one of the most important members, and condenser heat exchangers and auxiliary electric heating tanks are important links in heat exchange. However, in terms of structure, they all fail to meet the predetermined requirements more ideally.

From related technologies and applications, it can be found that the current water module is large in size and occupies a large area; the internal structure is disorderly distributed and the pipeline is complicated, resulting in high production quality requirements and large hidden dangers. When the unit is commissioned or maintained, due to the lack of optimization in the structural design, it is difficult to disassemble the panels during the installation and commissioning of many units. The above problems require redesigning the structure of the water module, so as to solve the various inconveniences of installation, commissioning and after-sales maintenance.

The Chinese patent number of the prior art: CN201620454355.2 The utility model application provides a water module, including: a shell, a chassis, a heat exchange system and an electric control box. The top of the shell has a maintenance port; The bottom; the heat exchange system is set on the chassis. The heat exchange system includes an expansion tank, a liquid pump, a heat exchanger and a liquid tank. The expansion tank and the liquid pump are arranged on one side of the chassis at intervals along the length of the chassis. The heater and the expansion tank are arranged on the chassis at intervals along the width direction of the chassis; the electric control box is movably arranged at the maintenance port, and the electric control box is connected with the heat exchange system. According to the water module of the utility model, the difficulty of connecting various components between the heat exchange systems is reduced, the connecting pipelines are neat and orderly, and the total length of the connecting pipelines is reduced, thereby reducing the cost and occupancy of the connecting pipelines space, reducing the overall volume and cost of the water module. In addition, the maintenance and detection difficulty of the water module is effectively reduced, and the maintainability of the water module is improved.

Although the above patents solve the problem of inconvenient installation and debugging caused by the electric control box on the other side of the unit, they also have the following disadvantages: there is no electric heating tank in the unit, and auxiliary heating is not possible; there is no additional electric heating tank inside the unit, and the unit is in the The risk of freezing and cracking of the heat exchanger increases at low ambient temperature; the heat exchangers and water tanks of the unit are placed in sequence, and the compactness is not high.

There is also a similar technical solution in the prior art, as shown in FIG. 1 , a common water module structure. The electric heating tank 101 and the high-efficiency tank heat exchanger 102 are separately arranged in the water module housing 100 . The high-efficiency tank heat exchanger refers to a heat exchanger structure commonly referred to by those skilled in the art on the market. It usually adopts the form of a tank body, and coiled heat exchange tubes are used inside the tank. Refrigerant tubes for efficient heat exchange. When in a low temperature environment, the water temperature in the high-efficiency tank heat exchanger 102 is too low and the heat pump system fails to start the heat pump system due to failure or other reasons, the water pump 105 and the water module waterway system 106 are at risk of being damaged by freezing. Moreover, the connection structure is relatively complicated, which is inconvenient for processing, manufacturing and maintenance.

Common water modules are generally installed vertically on the wall, and the electric heating tank is usually used for auxiliary heating, so as to keep the inside of the water module structure from being damaged by freezing. For the electric heating tank of the prior art, the flow direction of water is generally bottom-in and top-out, and when the water system of the unit fails to operate due to a fault, because the outlet pipe 107 of the electric heating tank 101 is not at the lowest end, it will cause The accumulated water at the bottom of the electric heating tank cannot be drained. When the ambient temperature is very low in winter, it is easy to cause the risk of freezing and cracking of the electric heating tank 101 tank body or electric heating wire due to freezing. As shown in FIG. 1 , the prior art does not take into account the problem of emptying the bottom of the electric heating tank 101 itself, so as to prevent the electric heating tank 101 itself from freezing and cracking in winter.

Therefore, the prior art still needs to be improved and developed.
