A connection structure of an enthalpy-increasing pipeline for a hot air blower

Abstract

The invention discloses a connection structure of an enthalpy-increasing pipeline for a hot air blower, which belongs to the technical field of hot air blowers. The invention includes an enthalpy booster and an electronic expansion valve, the enthalpy booster and the electronic expansion valve are connected through a pipeline, and the pipeline includes a plurality of vertical tubes connected by U-shaped tubes, and the U-shaped tubes are wrapped with anti-vibration glue, and the anti-shock glue includes The fastening shock-absorbing layer, sound-absorbing layer and protective layer are arranged sequentially from the inside to the outside. The main purpose of the present invention is to effectively reduce the noise caused by the vibration of the enthalpy-increasing pipeline, and to meet the required shock and noise reduction effects on the enthalpy-increasing pipeline. At the same time, it can be tightly wrapped on the enthalpy-increasing pipeline to avoid falling off. Easy to install and operate.

Description

technical field [0001] The invention belongs to the technical field of hot air blowers, and more specifically relates to a connection structure of an enthalpy-increasing pipeline for a hot air blower. Background technique [0002] The enthalpy-increasing pipeline usually includes pipeline parts, mufflers, electronic expansion valves and stop valves. Under low ambient temperature, it can effectively increase the temperature and pressure of the suction inlet of the compressor, so that the hot air unit can operate efficiently in harsh environments. With the requirement of strong heating at low ambient temperature, at the same time, it mainly relies on the heat of outdoor air to heat the indoor air, saving a lot of power resources. However, the internal pressure of the supplementary gas enthalpy increasing compressor shows periodic high and low changes during operation, and the refrigerant pressure in the enthalpy increasing pipeline is not constant, which causes the refrigerant...

AI Technical Summary

Problems solved by technology

However, the internal pressure of the supplementary gas enthalpy increasing compressor shows periodic high and low changes during operation, and the refrigerant pressure in the enthalpy increasing pipeline is not constant, which causes the refrigerant to flow through the increasing enthalpy in the form of turbulent fluid pulses. The enthalpy pipeline is affected by the turbulent fluid pulse. The vibration of the enthalpy pipeline is very violent and the amplitude and period of the vibration are irregular. However, the enthalpy pipeline is bound to break when it is in this vibration for a long time. Affect the normal and reliable operation of the hot air blower

[0003] In view of the above problems, in the prior art, a noise reduction and shock absorption device is added to the enthalpy-increasing pipeline to achieve a certain effect of noise reduction and shock absorption. There are still deficiencies in the problem, and it is difficult to fasten and wrap it on the enthalpy-increasing pipeline, and there is a problem that it is easy to fall off, thereby further reducing the effect of noise reduction and shock absorption. At the same time, the noise reduction and shock absorption device used in the prior art also has problems such as inconvenient installation and operation
