Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a pipeline connection structure of an environmental protection heat pump unit. Background Technique

[0002] A heat pump unit is a circulating system composed of devices such as a compressor - heat exchanger - throttler - heat absorber - compressor, etc. The refrigerant circulates in the system under the action of the compressor. It completes the process of boosting pressure and temperature in the gaseous state in the compressor (the temperature reaches up to 100 °C). After entering the heat exchanger, it exchanges heat with the air and is cooled and transformed into a liquid state. When it runs to the heat absorber, the liquid quickly absorbs heat and evaporates to be transformed into a gaseous state again, and at the same time the temperature drops to -20 °C - 30 °C. At this time, the air around the heat absorber will continuously transfer low-temperature heat to the refrigerant. The continuous circulation of the refrigerant realizes the process of converting low-temperature heat in the air into high-temperature heat and heating cold water. There is often a complex pipeline design in the heat pump unit, and the span of some pipelines is relatively large. If such pipelines with a large span are only fixed at both ends, huge shaking often occurs during the operation of the equipment, which is likely to cause pipeline fracture or connection failure at both ends of the pipeline.

[0003] During the pipeline connection process, due to the need for a parallel design of two pipelines, a corresponding pipeline connection structure needs to be used. Referring to the "pipeline connection device" with the authorized patent number "CN207093943U", it can be known that this patent can be used to fix pipelines and adjust the distance between pipelines according to requirements. However, this device can only fix two pipelines arranged in parallel and still cannot be used for pipelines arranged in a cross manner, with poor practicability.

[0004] Therefore, we propose a pipeline connection structure of an environmental protection heat pump unit. Content of the Utility Model

[0005] The purpose of the utility model is to provide a pipeline connection structure of an environmental protection heat pump unit to solve the problems raised in the above background technique.
