Description

Technical Field

[0001] This disclosure relates to a modular heat pump system. Background Technology

[0002] A typical heat pump system usually includes a motor, a compressor, a condenser, and an evaporator. The motor drives the compressor to compress gaseous refrigerant and deliver the compressed high-pressure gaseous refrigerant to the condenser. The condenser cools the high-pressure gaseous refrigerant into a liquid state and delivers the liquid refrigerant to the evaporator. Then, the evaporator evaporates the liquid refrigerant into a gaseous state and delivers the remaining refrigerant back to the compressor.

[0003] However, conventional heat pump systems are typically factory-assembled monolithic structures, which are then transported to the installation site. This monolithic structure is primarily due to the generally large size of heat pump systems, the complex arrangement of components and piping, and the high integration requirements. Factory assembly allows for stringent quality control. These factory-assembled systems have fixed dimensions, thus imposing specific requirements on the installation space; the space must have sufficient volume to accommodate the monolithic heat pump system. For example, while the installation space may have a larger total footprint than the monolithic heat pump system, it cannot be installed if the space does not have a larger local footprint. Furthermore, the large size of such monolithic heat pump systems presents inconveniences in terms of transportation and operation. Utility Model Content

[0004] To overcome the aforementioned deficiencies in the prior art, this disclosure provides a modular heat pump system comprising a motor module, a compressor module, a condenser module, and an evaporator module. The motor module is detachably connected to the compressor module; the compressor module is detachably connected to the condenser module and located upstream of the condenser module relative to the refrigerant flow direction; the condenser module is detachably connected to the evaporator module and located upstream of the evaporator module relative to the refrigerant flow direction; and the evaporator module is detachably connected to the compressor module and located upstream of the compressor module relative to the refrigerant flow direction. Each of the motor module, compressor module, condenser module, and evaporator module is modularized such that they are independent of each other and can be assembled on-site to form the modular heat pump system. Accordingly, the modular heat pump system can be installed on-site, and the motor module, compressor module, condenser module, and evaporator module can be installed in appropriate locations according to the requirements or limitations of the installation site, thereby reducing the size requirements of the installation site.

[0005] Furthermore, the modular heat pump system also includes a high-pressure pipe connected between the compressor module and the condenser module. This enables the stable delivery of high-pressure gaseous refrigerant.

[0006] Furthermore, the modular heat pump system also includes an expansion valve connected between the condenser module and the evaporator module. This allows for precise control of the liquid refrigerant flow rate.

[0007] Furthermore, the modular heat pump system also includes a low-pressure pipe connected between the evaporator module and the compressor module. This enables the stable delivery of low-pressure gaseous refrigerant.

[0008] Furthermore, the motor module is provided with at least one connection interface for rigid connection with the compressor module, and the at least one connection interface is a flange. Furthermore, the compressor module is provided with at least three connection interfaces for rigid connection with the motor module, the condenser module, and the evaporator module respectively, and the at least three connection interfaces are flanges. Furthermore, the condenser module is provided with at least two connection interfaces for rigid connection with the compressor module and the evaporator module respectively, and the at least two connection interfaces are flanges. Furthermore, the evaporator module is provided with at least two connection interfaces for rigid connection with the compressor module and the condenser module respectively, and the at least two connection interfaces are flanges. Accordingly, convenient connections can be achieved through standardized interfaces.

[0009] Furthermore, the modular heat pump system also includes a main control system for monitoring and controlling the motor module, the compressor module, the condenser module, and the evaporator module. Each of these modules includes its own auxiliary control system, which is communicatively connected to the main control system. This reduces maintenance time, particularly by approximately 50%, and allows for independent updates and maintenance of each module.

[0010] In summary, this disclosure modularizes the motor, compressor, condenser, and evaporator of a heat pump system into independent motor modules, compressor modules, condenser modules, and evaporator modules, thereby adapting to a wider range of possible installation space conditions. For example, in situations where the installation space mentioned above does not have a larger local footprint than a monolithic heat pump system, the motor module, compressor module, condenser module, and evaporator module can be installed separately in smaller local footprints and connected by corresponding pipelines to form a modular heat pump system; alternatively, the motor module, compressor module, condenser module, and evaporator module can even be installed in multiple different installation spaces (e.g., rooms) and connected by corresponding pipelines to form a modular heat pump system. Therefore, the modular heat pump system of this disclosure, which can be installed on-site, significantly improves the adaptability to installation space. Attached Figure Description
