Description

Technical Field

[0001] The utility model relates to the technical field of steam heat pumps, in particular to a modular assembled steam heat pump host. Background Art

[0002] Heat pump technology is a new energy technology that has attracted much attention worldwide in recent years. A heat pump is a device that can obtain heat from a low-temperature object, transfer heat to a high-temperature object with high potential energy as compensation. Through a heat pump, people can obtain a large amount of low-grade heat energy from nature or industrial waste heat, and convert it into high-grade heat energy that can be used. The most commonly used and most mature technologies are mechanical compression heat pumps and absorption heat pumps. According to the different external heating temperatures of the heat pump system, the heat pump system can be divided into normal temperature hot springs and high temperature hot springs. A high-temperature heat pump generally refers to a heat pump with a heating water temperature higher than 60°C (i.e., high-temperature hot water) or an air outlet temperature of more than 80°C (i.e., a high-temperature drying heat pump). If the heating temperature exceeds 100°C, steam can theoretically be generated under normal pressure, and this heat pump can be used as a steam generator to meet the needs of industry and daily life. Currently, the available steam is mainly generated by heating water in a boiler. Regardless of the fuel used (oil, gas, coal, etc.), the energy utilization efficiency is relatively low and there is also the problem of air pollution. Therefore, compared with steam boilers, high-temperature heat pump steam engines are a new type of heat pump product that is energy-saving, environmentally friendly, and has market prospects.

[0003] Existing steam heat pumps need to design steam heat pump hosts of different sizes according to different steam volume requirements, which has a long development cycle and high labor costs. The present invention adopts a unified single-module host and uses multiple single modules for assembly according to different steam volume requirements, which can greatly save development time and labor costs. At the same time, a single module can also be installed and used as an independent host by adding some appearance and electronic control structure.

[0004] Usually, the types of parts required for steam heat pump hosts of different sizes will vary greatly, and the structural consistency is poor. Single-module hosts are assembled using the same modules, with high parts uniformity and skilled production and installation, and the required debugging time can be greatly reduced.

[0005] Conventional steam heat pump mainframes have limited installation space and are difficult to maintain after sales. In the present invention, a single module can be assembled offline, and the overall installation can be carried out by hoisting or fork mounting. The special fixing method is simple and convenient to install, and after-sales maintenance can be performed by removing the single module.

[0006] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the utility model, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art known to ordinary technicians in this field.
