PRODUCT DESIGN 25 This section gives a basic description of cooling unit opera- tion, its various components and their basic operation. Ensure your system is properly sized for heat gain and loss according to methods of the Air Conditioning Contractors Association (ACCA) or equivalent. CONDENSING UNIT The condenser air is pulled through the condens[...]

PRODUCT DESIGN 26 The ASX [16 & 18], ASZ [16 & 18], DSX16 and DSZ16 series split system units use a two-stage scroll compressor. The two-step modulator has an internal unloading mechanism that opens a bypass port in the first compression pocket, effectively reducing the displacement of the scroll. The opening and closing of the bypass port [...]

PRODUCT DESIGN 27 CAPACITY CONTROL During the compression process, there are several pockets within the scroll that are compressing gas. Modulation is achieved by venting a portion of the gas in the first suction pocket back to the low side of the compressor thereby reducing the effective displacement of the compressor. See Figure A. Full capacity [...]

SYSTEM OPERA TION 28 COOLING The refrigerant used in the system is R-410A. It is a clear, colorless, non-toxic and non-irritating liquid. R-410A is a 50:50 blend of R-32 and R-125. The boiling point at atmo- spheric pressure is -62.9°F. A few of the important principles that make the refrigeration cycle possible are: heat always flows from a warme[...]

SYSTEM OPERA TION 29 DEFROST CYCLE The defrosting of the outdoor coil is jointly controlled by the defrost control board and the defrost thermostat. Solid State Defrost Control During operation the power to the circuit board is controlled by a temperature sensor, which is clamped to a feeder tube entering the outdoor coil.

SERVICING 66 S-106 OVERFEEDING Overfeeding by the expansion valve results in high suction pressure, cold suction line, and possible liquid slugging of the compressor. If these symptoms are observed: 1. Check for an overcharged unit by referring to the cooling performance charts in the servicing section. 2. Check the operation of the power element i[...]

SERVICING 67 4. Review the technical information manual or specification sheet for the model being serviced to obtain the design subcooling. 5. Compare the hi-pressure reading to the "Required Liquid Line Temperature" chart (page 43). Find the hi-pressure value on the left column. Follow that line right to the column under the design subc[...]

SERVICING 68 2. Remove the orifice or tube strainer assembly and re- place. 3. Replace liquid line drier, evacuate and recharge. CHECKING EQUALIZATION TIME During the "OFF" cycle, the high side pressure bleeds to the low side through the fixed orifice restriction device. Check equalization time as follows: 1. Attach a gauge manifold to th[...]

SERVICING 69 NOTE: At least twelve (12) inches of the suction line immediately out of the compressor stub must be discarded due to burned residue and contaminates. 1. Remove compressor discharge line strainer. 2. Remove the liquid line drier and expansion valve. 3 Purge all remaining components with dry nitrogen or carbon dioxide until clean. 4. In[...]

SERVICING 70 4. Two-Stage Condensing Unit: The maximum length of tubing must not exceed 80 feet where indoor coil is located above the outdoor unit. NOTE: When the outdoor unit is located above the indoor coil, the maximum vertical rise must not exceed 25 feet. If the maximum vertical rise exceeds 25 feet, premature compressor failure will occur du[...]
