Modern The refrigeration equipment market has ceased to be a monopoly of several Western giants, giving way to high-quality Asian manufacturers. One of the key players in this field has become a Chinese company, whose compressors can today be found in every third household refrigerator in the post-Soviet space. Many owners of household appliances do not even suspect that the “heart” of their unit is precisely this reliable unit, often mistakenly believing that a more well-known European or American analogue is installed inside. Understanding whether Jiaxipera, whose compressors today can be found in every third household refrigerator in the post-Soviet space. Many owners of household appliances do not even suspect that the “heart” of their unit is precisely this reliable unit, often mistakenly believing that a more well-known European or American analogue is installed inside. Understanding that which compressor is installed in your model is critically important when selecting spare parts for repair or replacement.
You can recognize the manufacturer of the motor not only by the markings on the nameplate, but also by the characteristic sound of operation, dimensions and even the country of assembly of the refrigerator itself. The units Jiaxipera are famous for their energy efficiency and adaptability to voltage fluctuations in the network, which makes them an ideal choice for regions with unstable energy. However, like any complex equipment, they require the right approach to fault diagnosis and competent operation. In this article, we will analyze in detail what brands of equipment these devices are hidden in, how to decipher their codes and whether it is worth changing a failed unit yourself.
Main partner brands of Jiaxipera
Chinese corporation Jiaxipera (full name Zhejiang Jiaxipera High Performance Motor Co., Ltd.) is one of the largest OEM suppliers in the world. This means that they produce components that are then installed on refrigerators under the names of other, more well-known brands. Most often, these compressors can be found in equipment assembled in factories in China, Turkey, India and Southeast Asian countries. Knowing the list of partners helps you quickly find a compatible analogue in the event of a breakdown.
Units Jiaxipera are especially common in the budget and mid-price segments. Large concerns order batches of motors under their own internal codes, so there may not be a refrigerator brand logo on the compressor housing. Instead, there will be a logo Jiaxipera or Embraco (after the merger of assets), which sometimes misleads inexperienced craftsmen.
- 🏭 Haier is one of the largest consumers, uses these compressors in many models of the Cool i Smart.
- ❄️ Beko and Arctic —the Turkish giant is actively integrating Chinese engines into its assemblies for the CIS and European markets.
- 🔧 Indesit and Ariston (assembly China/Russia)—in new models after 2015, units are often installed Jiaxipera.
- 🌏 Hisense, Midea, TCL —brands that often use their own or subsidiary production, closely related to Jiaxipera.
⚠️ Attention: Not all compressors in refrigerators of the listed brands are Jiaxipera. The manufacturer may change suppliers depending on the batch and the assembly plant. Always check the markings on the nameplate located on the black metal motor housing before ordering a replacement.
It is important to note that Jiaxipera absorbed some of the company's assets Embraco, which led to the emergence of hybrid markings. Now a compressor produced at factories Jiaxiperamay have the Embraco logo, but the model will correspond to the lines of the Chinese manufacturer. This global change in the supply chain simplifies logistics, but complicates identification for the end user. refrigeration equipment simplifies logistics, but complicates identification for the end user.
How to decipher the markings and model of a compressor
Identifying a specific engine type is the first step to successful repair. There is always a metal plate or sticker with technical information on the top of the black casing (crankcase). Compressors Jiaxipera are characterized by a certain coding system that informs the technician about the refrigerant, power and type of cooling. The ability to read these codes allows you to avoid purchasing the wrong spare part.
Usually the marking begins with letters indicating the series or type of refrigerant, followed by a digital power code. For example, in models based on R600a (isobutane) the letter "G" or "H" is often found at the beginning of the code. Models on R134a may be designated "F" or "T". It is important to pay attention not only to the model, but also to the electrical parameters: voltage (220-240V) and frequency (50/60Hz).
Let's consider the structure of a typical code using an example Jiaxipera:
- The first group of characters indicates a series (for example, QD - standard series, YZ —series for deep freezing).
- The following numbers indicate the cylinder volume or refrigeration capacity in BTU/h.
- The last letters may indicate the type of oil or modification of the housing.
For accurate decoding, it is best to use a cross-reference (correspondence table), since the visual similarity of different models can be deceptive. An error in selecting a compressor based on power will lead to the fact that the refrigerator will not freezing enough or, conversely, work non-stop, quickly wearing out.
Technical characteristics and series of compressors
Jiaxipera engineers have developed several lines of compressors, each of which is optimized for specific tasks. Understanding the differences between the series Jiaxipera have developed several lines of compressors, each of which is optimized for specific tasks. Understanding the differences between series G, H and F is necessary for the correct selection of an analogue. These devices differ not only in geometric dimensions, but also in starting characteristics, which directly affects the choice. start relay.
Series G (for example, GZH) is perhaps the most common line for medium-sized household refrigerators. They are distinguished by their compact size and low noise level. These units often operate on environmentally friendly refrigerant R600a. minimum filling (only 40-60 grams). A feature of the series is its high energy efficiency class A+ and higher.
Series H i F is often aimed at more powerful refrigeration cabinets or working with refrigerant R134a. They have a large cylinder displacement and are capable of providing intensive cooling in No Frost chambers. It is important to consider that compressors on R134a require the use of synthetic POE oil, while R600a operate on mineral or semi-synthetic oil.
| Series | Refrigerant type | Cooling capacity | Application |
|---|---|---|---|
| GZH / G | R600a | 80 - 120 W | Small and medium refrigerators |
| H | R134a / R600a | 100 - 160 W | No Frost refrigerators, large chambers |
| QD | R134a | 90 - 140 W | Standard household models |
| YZ | R600a | 60 - 90 W | Chest freezers, minibars |
The parameter COP (Coefficient of Performance) deserves special attention - the efficiency coefficient in modern models Jiaxipera it can reach values of 1.6-1.8, which is an excellent indicator for piston engines. compressors. A high COP means that for every watt of electricity expended, the unit produces more cold, which directly reduces electricity bills.
Failure symptoms and unit diagnostics
Compressor diagnostics Jiaxipera is not much different from checking other brands, but has its own nuances First. a sign of trouble is often a change in the sound background. A working motor runs smoothly, with a slight hum and a periodic click of the thermal relay. If you hear a metallic clanging sound, or the hum becomes intermittent, this is an alarm signal.
A common problem - thermal protection. The compressor heats up, the internal relay is activated, and after a while it turns off. time cools down and tries to start again. This cycle can be repeated endlessly. The reasons can be different: from simple contamination of the capacitor (radiator behind the refrigerator) to an interturn short circuit in the motor windings.
- 🔥 Overheating: The compressor housing is so hot that it is impossible to touch it (normal - 70-90°C, critical - above 110°C).
- 🔌 No starting: A relay click is heard, the hum lasts 2-3 seconds, then the shutdown click. This often indicates that the piston group is jammed.
- ❄️ Poor cooling: The motor runs continuously, but the temperature in the chamber does not drop below +10°C. There may be a loss of valve performance.
For accurate diagnosis, you must use a multimeter. Check the resistance between the winding contacts (starting, operating and common). A scatter of values or a “break” reading (one on the screen) indicates a burnt-out winding. It is also important to check insulation resistance between the housing and the contacts - it should be infinitely large.
⚠️ Attention: Never check the operation of the compressor by connecting it directly to the network without a starting relay and a capacitor (if it is in the circuit). This may result in immediate burnout of the windings or electric shock. Use only a standard or proven connection diagram.
Instructions for replacing the compressor with your own hands
Replacing a compressor Jiaxipera is a task for an experienced technician, requiring special equipment: a burner, a vacuum pump, a pressure gauge station and a refrigerant bottle. However, if you have soldering skills and understand the principles of operation of the refrigeration circuit, a theoretical algorithm of actions will help you control the process or perform it yourself.
The process begins with completely defrosting the refrigerator and accessing the back wall. It is necessary to carefully bite off the copper tubes suitable for the compressor (filling, discharge and suction) with pliers. The old motor is dismantled by unscrewing the bolts securing it to the frame. At this stage, it is important not to damage the remaining elements of the system.
☑️ Checklist for preparation for replacement
Installing a new unit Jiaxipera requires compliance with several rules. Firstly, the plugs from the pipes of the new compressor are removed only at the time of soldering, so that moisture from the air does not get inside. Secondly, it necessarily changes filter-drier on the capacitor. Thirdly, soldering must be done quickly, using solder with silver, so as not to overheat the thin-walled tubes.
Soldering order:1. Solder the discharge pipe (thin tube).
2. Solder the suction pipe (thick tube).
3. Install and solder the filter drier.
4. Check the tightness with nitrogen under a pressure of 10-15 bar.
After mechanical installation and checking for tightness, the system is evacuated for 15-20 minutes. This is a critical step for removing moisture and air. Only after creating a vacuum is filling done refrigerant strictly according to the weight indicated on the refrigerator nameplate.
Frequently asked questions and operating nuances (FAQ)
Owners of equipment with compressors Jiaxipera often faced with the same questions. Below are answers that will help dispel popular myths and clarify maintenance details.
Is it possible to replace a Jiaxipera compressor with Embraco or Danfoss?
Yes, replacement is possible, but only if the cooling capacity (in Watts or BTU), type of refrigerant and overall dimensions match. Often compressors Jiaxipera are complete analogues of Embraco series models NT or NL, but may differ in body height or tube arrangement.
Why is the new Jiaxipera compressor buzzing loudly?
Humming can be caused by improper installation (vibration is transmitted to the refrigerator body), lack of rubber damper washers, or a defect in the unit itself. It can also make noise if scale gets inside during soldering and clogs the valves.
How long does a Jiaxipera compressor last on average?
The average service life is 7-10 years, subject to operating conditions. However, practice shows that with a stable voltage in the network and a clean heat exchange system, they can operate for 12-15 years without intervention.
Where is the serial number to check the warranty?
The serial number is stamped on a metal nameplate attached to the compressor housing. Also, a duplicate number is often on a sticker inside the refrigerator compartment or on the back wall of the cabinet.
To summarize, we can say that compressors Jiaxipera have established themselves as the “workhorses” of the modern refrigeration market. They are not without the disadvantages inherent in the mass market, but with proper selection and installation they provide reliable refrigeration supply. The main thing is not to skimp on the quality of spare parts and the qualifications of the technician during repairs.
