It should be understood by those skilled in the art that the foregoing heat exchanger may be an evaporator or a condenser. In addition, it should be noted that the preset operating temperature range of the muffler is generally 30-90 ℃, and a large number of simulation tests show that the muffler on most air conditioner pipelines is less affected by the temperature of the refrigerant when the muffler is in the temperature range. It will be understood, of course, that the predetermined operating temperature range is related to the structure and material of the muffler itself, and the actual application is in general, and the corresponding predetermined operating temperature range may be selected according to the specific muffler material and model, which is not limited in any way.
In order to better understand the technical scheme of the invention for the person skilled in the art, the main principle of solving the problem of unsatisfactory silencing effect of the technical scheme of the invention is briefly described as follows:
speed of sound of refrigerant medium:
wherein, c 0 For medium sonic velocity, κ is the adiabatic index, R is the gas constant, and T is the temperature.
For a single expansion chamber muffler, the muffling frequency is satisfied,
wherein f is the muffling frequency, c 0 For medium sonic velocity, l is the expansion chamber length.
In practical engineering applications, it is desirable to reduce a certain frequency (i.e. the frequency of the ideal state) f 0 The muffler designed by noise under the condition of different working conditions has different refrigerant temperatures, and the temperature difference between the suction state and the exhaust state can reach more than 60 ℃.
Sound damping frequency f of actual sound damper 1 Frequency f from ideal state 0 There is a certain deviation, resulting in a weakening of the sound damping performance of the muffler.
In order to make the sound elimination frequency f of the actual sound eliminator 1 Frequency f from ideal state 0 More closely, the invention adds a temperature control module at the front section of the muffler to ensure the temperature T of the refrigerant flowing out of the temperature control module 1 Ideal refrigerant temperature T when designing muffler 0 The device is close to the muffler, so that the influence of the temperature of the refrigerant received by the muffler can be eliminated, and the problem of unsatisfactory noise elimination effect of the muffler can be avoided.
In some specific embodiments, the temperature control module 5 may specifically include: a first temperature sensor, a heater, a refrigerator, and a controller; the first temperature sensor is used for detecting the temperature of the outlet of the temperature control module 5 corresponding to the refrigerant circulating pipeline; a heater for heating the pipe section upstream of the muffler 4; a refrigerator for refrigerating a pipe section upstream of the muffler 4; and a controller for controlling the heater and the refrigerator to be opened and closed according to the temperature value detected by the first temperature sensor. The specific control process of the controller is as follows:
when the temperature value detected by the first temperature sensor is lower than or close to the lower limit temperature value of the preset working temperature range, the controller controls the heater to be started; when the temperature value detected by the first temperature sensor reaches a first preset intermediate temperature value in a preset working temperature range, the controller controls the heater to be turned off;

In a further embodiment, the first preset intermediate temperature value and the second preset intermediate temperature value may be specifically designed to be the same temperature value. It is of course understood that different temperature values can also be provided, for example, the first predetermined intermediate temperature value being smaller than the second predetermined intermediate temperature value.
In a further embodiment, when the first preset intermediate temperature value and the second preset intermediate temperature value are designed to be the same temperature value, the temperature control module 5 may be further loaded with a temperature compensation system, and the temperature compensation system may specifically include a second temperature sensor and a temperature compensation unit; the second temperature sensor is used for detecting the temperature of the refrigerant circulation pipeline 3 corresponding to the inlet of the muffler; when the absolute value of the difference value between the temperature value detected by the second temperature sensor and the first preset intermediate temperature value exceeds the preset temperature difference value, the temperature compensation unit sends a temperature compensation signal to the controller, and the controller can readjust the temperature in the refrigerant circulation pipeline according to the compensation signal so as to keep the absolute value of the difference value within the preset temperature difference value. Through designing temperature compensation system, can make the refrigerant temperature of inflow silencer import department remain a certain temperature value near first default intermediate temperature value all the time, be favorable to guaranteeing the noise elimination effect of silencer.
