47 Gas Powered Valves valves are uniquely constructed to use discharge pressure to close. These valves are typically used for low temperature applications in wet return lines on liquid recirculation systems or on the liquid open construction, pressure drop is minimal in suction or wet return drum. Being pressure powered to close, this valve can overcome position in the event that power to the pilot solenoid is inadvertently interrupted (i.e. a power failure), during hot gas defrost. This prevents The S9A, normally closed, gas powered suction stop valve is a pilot operated valve but uses an external source of higher pressure gas to operate the valve, and, therefore requires no minimum pressure drop to open. The external gas pressure for the Type S9A must be at least bar ( psi) above valve internal upstream pressure for positive opening. This valve is normally closed. The S9A valve is designed to promptly and fully open or close under or unsuitable, such as viscous oil conditions, location in a vertical pipeline, or where very low valve pressure drop is required. This valve is a two-position valve using condenser gas pressure acting upon a piston for opening, and a strong spring for closing. A twin pilot solenoid valve assembly (S9) serves to admit condenser gas pressure to the piston for opening and to bleed this gas pressure to the suction line for valve closing.

74 Defrost Controller user friendly, device for controlling the sequence of events that occur during system defrost cycles. The controller may be applied to both industrial and commercial refrigeration systems, and is suitable for use on hot gas, electric, or water defrost applications. Features Basic Operating Modes three basic modes below. Normal Operation: Defrost cycles occur according to any of the initiation and termination modes. Initiation modes: constant remote, or exact remote. Termination modes: Weekend Operation: Allows the user to specify a special schedule Equalization Cycle: The equalization phase can reduce or eliminate system disruptions and sudden compressor loading caused by warm reduction of vapor propelled liquid. The length of this equalization Fan Delay Cycle: This allows any remaining droplets of water on the evaporator coil to freeze, so they are not blown into the refrigerated and can vary from to minutes. Holiday Operation: Allows the user to specify a holiday schedule that occurs one-time only for a period of one to six days. At the end of the Within each of these operating modes, the controller will initiate or terminate defrost cycles based on a variety of criteria. Hot Gas Defrost Defrost Cycle following sequence when initiating a defrost cycle. Pump Out Cycle: This prepares the evaporator for defrost by allowing the liquid refrigerant in the evaporator to be pumped or drained out through the suction line. The length of this pump out cycle is user Soft Gas Cycle (optional): Hot Gas Cycle: can vary from to 4 minutes. This cycle may also be terminated before the time expires by an analog temperature measurement that has reached its pre-set limit, or a closed remote contact. 74

140 Thermostatic Expansion Valves (TXV) Ammonia Applications Only Thermostatic expansion valves for ammonia applications require special design considerations due to the erosive effects of ammonia other components of ammonia systems, the types D and A valves are made from steel and steel alloys. valve port causes valve seat erosion or wire drawing to occur. This effect is further aggravated by high velocity ammonia mixed with dirt or scale passing through the port of the expansion valve. Fortunately, seat erosion can be minimized and valve life extended if the following reducing the pressure drop across the port line vapor is prevented by adequately sizing liquid lines and providing TXVs ammonia systems. For further information on the use of this dryer with ammonia systems, refer to page of this catalog. Step : can be accomplished with the use of a removable discharge tube or the nozzle of a refrigerant distributor. These components reduce the velocity and pressure drop at the expansion valve port by introducing a restriction or added pressure drop in the valve outlet passage. The removable discharge tube is threaded into the outlet of the type type A valves. The discharge tube is the principle difference between The discharge tube in the outlet passage must be removed when the discharge tube is not removed from the valve, the combination of the discharge tube and distributor nozzle may create an excessive pressure 47-0 for further information on ammonia distributors. employ a discharge tube since their valve outlets are designed to serve Cold storage plants often have large centralized ammonia systems consisting of many evaporators connected to one or more large space temperature.

146 Thermostatic Expansion Valves Selection Procedure. Determine the pressure drop across the valve Subtract the evaporating pressure from the condensing pressure. The condensing pressure used in this calculation should be the minimum operating condensing pressure of the system. From this value, subtract all other pressure losses to obtain the net pressure drop across the valve. Be sure to consider all of the following possible sources of pressure drop: () friction losses through refrigeration lines including the evaporator and condenser; () pressure drop across liquid line pressure loss (gain) due to the vertical lift (drop) of the liquid line, see Table. Table Table the valve ratings shown in the tables. Once the desired valve rating has been located, determine the nominal capacity of the valve from the second column of the table. On multiple evaporator systems, select each valve on the basis of individual evaporator capacity. 4. Determine if an external equalizer is required The amount of pressure drop between the valve outlet and bulb location will determine if an external equalizer is required. The systems. Use an externally equalized valve when pressure drop between the valve outlet and bulb location exceeds values shown in Table.

As with the steel distributors, the dispersion cone is Satellite, and the nozzle is stainless steel. Distributor tube connections are available for 6, 4, and 6 OD aluminum tubing. Aluminum brazing techniques require more space between circuits than copper to brass brazing. As a result, the maximum number of circuits is less than for comparable brass models. Applying Distributors to Thermostatic Expansion Valves employ a discharge tube. The discharge tube reduces refrigerant velocity across the valve port, preventing premature pin and seat erosion. When a distributor is used with these valves, the distributor nozzle performs the discharge tube s function. The discharge tube must then be removed from the valve to avoid excessive pressure drop. Distributor performance is best obtained if the distributor is bolted to the distributor, or if a shut off valve is installed between them, use a short, straight piece of pipe to connect the two. The pipe recommended since they hinder proper distribution.

The bulb of the of bulb that incorporates a low wattage heater. A -watt heater is supplied as standard. The insert bulb is installed in the accumulator or surge drum at the point of the desired liquid level. As the level at the insert bulb drops, the electrically added heat increases the pressure within the thermostatic element and opens the valve. As the liquid level at the bulb rises, the electrical input is balanced by the heat transfer from eventually shuts off. The evaporator pressure and spring assist in providing a positive closure.

The insert bulb assembly is provided Installation Electrical Connections The heater is provided with a two-wire neoprene covered cord two Figure. The heater circuit must be interrupted when refrigeration is not required and the compressor is cycled off. This will prevent shortening the life of the heater thermostat. To accomplish this, the heater is wired in parallel (on the compressor side) with the control or power relay, the holding coil of the compressor magnetic starter, or the liquid line solenoid valve.

This design criterion also prevents the return of any oil from the low side in the normal manner. with a surge drum, the liquid leg is extended downward below the point where the liquid is fed off to the evaporator and a drain valve is provided to allow periodic manual draining as shown in Figure. valve is usually provided at the bottom of the chiller shell.

The tendency to overfeed is due to the fact that the oil does not convey the heat from the low wattage heater element away from the bulb as rapidly as does pure liquid refrigerant. The bulb pressure is higher than normal and the valve remains in the open or partially open position.
