Product Uses

The Daikin JT300D-Y1L is a 10HP high-efficiency scroll compressor from Daikin's D series, utilizing R22 refrigerant. It features a displacement of 163 cm³/rev and delivers a cooling capacity of 29.6 kW (102,000 BTU/h). This model is widely used in air conditioning units, air dryers, drying equipment, and other industrial refrigeration systems powered by 3-phase 380V/50Hz. Daikin compressors have been proven through long-term application across different regions and climatic conditions worldwide, delivering stable and reliable performance.

The JT300D-Y1L adopts Daikin's proprietary asymmetric scroll technology. Compared to symmetric scrolls, the asymmetric design optimizes the refrigerant distribution path, reduces secondary expansion losses, and significantly enhances compression efficiency. Combined with axial compliance sealing technology, it achieves efficient sealing between the orbiting and fixed scrolls through an oil film effect, effectively minimizing gas leakage.

FAQ

Q1: Can you provide some specific application cases to illustrate the advantages of this compressor?

I. Hotel and Catering Industry

Case: Central Air Conditioning System in a 5-Star Hotel

A five-star hotel selected the Daikin JT300D-Y1L compressor as the core power for its guest room central air conditioning system. The large cooling capacity of 10HP (29.6 kW) easily meets the cooling demands of both guest rooms and public areas. Adopting Daikin's proprietary asymmetric scroll technology, the compressor operates at a noise level as low as 65 dB(A), ensuring a quiet and comfortable guest room environment that meets library-level silence standards. In heating mode, it operates stably even in low-temperature environments of -15°C, satisfying the winter heating needs of hotels in cold regions. The compressor's high-reliability design has enabled the hotel's air conditioning system to achieve over 10 years of trouble-free operation on average, significantly reducing maintenance costs.

II. Industrial Refrigeration and Cold Storage Equipment

Case: Refrigeration Unit for Food Cold Chain Cold Storage

In the food cold chain sector, the Daikin JT300D-Y1L compressor is widely used in medium-sized cold storage refrigeration systems (evaporating temperature -5°C to +10°C). With a displacement of 163 cm³/rev and a cooling capacity of 29.6 kW, it achieves a COP of up to 3.31 W/W. The system maintains stable operation even under frequent start-stop conditions. The built-in motor protection device effectively prevents overload and locked-rotor faults, ensuring temperature control accuracy within ±1°C, providing reliable assurance for the long-term storage of fresh food.

Selection Tip: For R407C eco-friendly refrigerant applications, please select the JT300DA-Y1L model from the same series.

III. Medical Cleanroom Engineering

Case: Cleanroom Air Conditioning System in a Hospital Operating Room

The cleanroom air conditioning system of a Grade III Class A hospital selected the Daikin JT300D-Y1L compressor. The large 10HP cooling capacity ensures a constant temperature and humidity environment even when large operating rooms are running at full load. The hermetic structure effectively eliminates the risk of refrigerant leakage, meeting the stringent air cleanliness requirements of medical environments. The wide voltage adaptability range (340-440V) ensures stable operation even during power grid fluctuations. The compressor's high-precision temperature control capability achieves an accuracy of ±0.5°C in the operating room, providing a safe and reliable air environment for various surgical procedures. The 10HP large cooling capacity configuration ensures stable cleanroom air conditioning performance even in situations with high personnel density and significant heat generation from equipment.
