Page 12: Chapter D - Layout And Components
D – Layout and Components Layout and Components The general layout and components location is the same for all dehumidifiers of current type, however some may vary, based on the dehumidifier’s specific options – refer to submittal documentation. Pic. D.1 below shows all/most available options, some of which may not be present on your dehumidifier. Dehumidifier Main Components Main Blower (1) is in the main blower compartment behind or next to the Compressor Compartment (3) with Main Electric Panel (2). Based on airflow requirements, number of main blowers may vary (up to four). Two blowers could be installed either side by side or stacked on a top of each other (Pic. D.1A); four blowers’ arrangement would have two stacks, shown on Pic. 1.DA, installed side by side. Min Outdoor Air (OA) Opening (4) has a motorized damper and filter(s). The Manual OA Damper (5) is usually used to set proper amount of outdoor air intake; in some cases, it could be equipped with modulating actuator for automatic adjustment of outdoor air intake. Outdoor‐installed dehumidifier would have louver(s) (76) installed at the OA opening. Min Exhaust Fan(s) (EF) Assembly (6) (fan and motorized damper) is located on the dehumidifier’s return air side; Exhaust Air opening in outdoor‐installed dehumidifier is equipped with louver(s) (76) also. Min Exhaust Fan Assembly is hinged and could be opened for better access to the fan electric box. Dehumidifier, equipped with Heat Recovery (HR) option, would have HR glycol coils (71), installed at the Min Exhaust (EF) and Min Outdoor Air (OA) openings, and HR pump (72), installed in return air compartment. If HR option is present, Min Exhaust Fan Assembly would normally be equipped with a filter rack. If dehumidifier is equipped with Purge option, additional Purge‐exhaust fan(s) (PF) (73) with motorized damper would be installed on dehumidifier’s return air side, as well as additional (“Purge”) Outdoor Air (POA) (74) opening(s), equipped with motorized dampers, would be located directly upstream of Main Filter Rack (9). Motorized Return Air (RA) damper (75) would be located between return air side and POA opening(s). Outdoor‐ installed dehumidifier would have louvers (76) installed at the Purge‐exhaust fan and Purge Outdoor Air openings. Refrigeration Evaporator coils (7) and water/glycol Reheat coils (8) are located directly downstream of the Main Filter Rack (9). Motorized Evaporator Bypass Damper (10) is located next to the evaporator coils; it by‐passes portion of air around evaporator, thus adjusting compressor circuit operation.

Page 16: Outdoor Air Fluid Cooler Layout And Components D
D – Layout and Components Outdoor Air Fluid Coolers Layout and Components . The general layout of AC options (air‐and water‐cooled) is shown on Pic.D.5 below with the outdoor fluid cooler NG‐V‐12, equipped with additional pump package (Fig.1) and NG‐V‐32 (Fig.2) as an example. While layout and main components are similar for all applicable AC options, there are some deviations (number of fans, composition, etc.). Refer to AC Options Basic View (Basic Information chapter) for additional information. 32 33 35 31 33 36 37 31 Pic. D.5 Cooling (AC) coils (31) (where heat from glycol mixture is rejected to the ambient air) is mounted onto metal frame, upstream (before) the fans (32), that pulls the air through the coils to absorb the heat. Normally, fluid cooler would have multiple coils and fans. Cooler NG‐V‐12 (Fig.1), comprised of two coils, mounted on the angle to each other, and two fans, presents a single block. Depending on the capacity, cooler could be comprised of up to six such single blocks, stacked side by side on the same frame and manifolded together – NG‐V‐32 is comprised of three such blocks. Cooler piping connections (33) are identified respectively (IN – OUT); In some cases, fluid cooler piping connection(s) may be located within pump package box (37), if fluid cooler is provided with one. Piping connection location may vary – refer to particular cooler labels, stickers, submittal and other documentation. Electric power is normally to be brought to disconnect (35) (if cooler is equipped with such), which feeds it to the electrical box (36), that contains cooler power and control apparatuses. Depending on fluid cooler specifics, location of electrical box may slightly differ; in some cases, electrical box may be incorporated into pump package or located on the opposite side of the fluid cooler. ... - Page 17 D – Layout and Components Fluid Coolers Pump Package.

Page 18: Chapter E - Sequence Of Operation
E – Sequence of Operation Sequence of Operation The dehumidifier’s ventilation system establishes the required airflow through the dehumidifier. The control system compares air temperature and humidity to their desired values (set points) and proceeds to dehumidify, cool or heat the recirculating air. If the dehumidifier is equipped with the pool water heating option, the pool water temperature is compared to its set point and pool heating is provided if required. Set Points The control system is constantly adjusting unit operation to achieve and maintain said parameters within couple degrees/percent of the set point. Refer to the dehumidifier’s main label for the design value of control parameters, as well as the following note. Note: To ensure the dehumidifier’s most economical operation, we recommend maintaining the following relationship between pool water and room air temperatures: Room Air T = Pool Water T + 2˚F Ventilation. The main blower runs continuously, establishing required. The main blower speed is pre‐set via adjustable variable signal. Minimum Exhaust Fan (EF), if dehumidifier is equipped with such option, directs portion of return air outdoors. Like main blower, exhaust fan(s) speed is also controlled via adjustable (pre‐set) variable signal, that varies based on scheduled ventilation mode (Occupied, Non‐Occupied and Spectator) or call for Economiser Mode (as part of Air Conditioning and/or Dehumidification operation). Minimum Outdoor Air (OA) damper, if dehumidifier is equipped with such option, opens to introduce fresh outdoor air into the premise. OA damper could be equipped with ON/OFF (simple fully open – fully closed) or modulating‐controlled actuator; latter one would be controlled same way as minimum exhaust fan. Purge (Additional Exhaust) Option. Along with Min Exhaust Fan and Min Outdoor Air damper, dehumidifier could have additional set of exhaust (purge) fan(s) (PF) and purge outdoor air damper (POA), commonly referred as Purge. Purge fan(s) and OA damper(s) function is to allow for higher exhaust and fresh air amount, up to complete (100%) air changeover (when all exhaust fans and OA dampers are at their max capacities). Purge Fan(s) and Purge Outdoor Air damper(s) are controlled in the same fashion as min exhaust fans and min outdoor air. Some dehumidifiers may be equipped with additional Return Air damper: it closes in event of complete air changeover, separating return air side of dehumidifier from supply side (refer to Layout and Components chapter, as needed, for respective devices’ location). Complete air changeover, triggered manually, is known as Purge Mode. Note. Externally installed Exhaust Fan(s) and Outdoor Air damper(s) could be also controlled by the ... -
Page 19: Heat Recovery Option E
E – Sequence of Operation Heat Recovery Option. Dehumidifiers, packaged with Minimum Exhaust Fan and Minimum Outdoor Air damper, could also have additional Heat Recovery (HR) closed‐loop glycol system. Heat Recovery loop (see Pic. E.1 below) consists of two coils (air‐to‐glycol heat exchangers) and a pump, establishing glycol circulation between them. One coil, installed at exhaust air opening, recovers portion of exhausted air energy, another coil, installed at outdoor air intake, transfers this captured energy to entering outdoor air. Pic. E.1 Space Heating When premise air temperature drops below the set point, the dehumidifier control system issues a call for Space Heating Mode and engages space heater (electric heater, hot water coil with valve, gas boiler etc.) by sending space heating signal, respective to space heater control type ‐ on/off, variable (0‐10VDC), etc. Air Conditioning, Dehumidification and Pool Heating. When premise air temperature goes over (exceeds) its set point, the dehumidifier control system issues a call for Air Conditioning Mode. Respectively, when premise air humidity goes over (exceeds) its set point, the dehumidifier control system issues a call for Dehumidification Mode. In some instances, these calls may co‐exist. To execute Dehumidification or Air Conditioning (Cooling) mode, control system, depending on current conditions, would resort to available means of cooling or dehumidification. Economiser Mode Option. Note. Economiser Mode requires dehumidifier to be equipped with full (min and additional) exhaust and outdoor air options! If outdoor air is dry and/or cool, it could be used to dehumidify and/or cool the premise. In this case, on call for Dehumidification or Air Conditioning mode(s), control system would simply increase exhaust fan(s) speed signal to direct more stale return air outside and bring in more outdoor (dry/cool) air in, thus reducing supply air humidity and/or temperature (as needed). E‐ ... - Page 20 E – Sequence of Operation Compressor(s) Whenever the compressor operates, the evaporator is always dehumidifying and cooling the return air. The heat removed from the air at the evaporator, as well as the heat from the compressor's action, must be rejected to one of three heat sinks: room (premise) air, pool water (if applicable) or outdoors. The control system will direct the heat to where it is needed based on room (air and pool water temperature) conditions: If room air is needed to be warmed up – more heat is diverted towards reheat coil; If pool water is needed to be warmed up – more heat is diverted towards pool heating coaxial heat exchanger (if dehumidifier is equipped with this option). Rest of the heat (if any) is diverted towards outdoors (outdoor fluid cooler, external heat sinks etc.) Compressor Circuit Operation Piping schematic for compressor circuit is shown on Pic. E.2. Schematic shows single compressor circuit (second compressor circuit schematic is the same) and common to both compressor circuits’ glycol cooling circuit. Circuit operation below applies to both compressors; compressors are staged – if first compressor’s capacity is not enough to satisfy the call, second compressor will be engaged after certain time delay. When a demand requires the compressor to operate, the following sequence occurs: Once blower operation, related safeties and timers are confirmed by the control system, following occurs: Compressor glycol pump starts, establishing cooling glycol/water flow through the compressor fluid circuit ‐ plate heat exchanger(s) and fluid cooling coils (reheat and/or fluid cooler or external cooling source). Pump down solenoid valve opens and once pressure stabilizes, the compressor starts. Based on the premise air temperature, the Reheat and AC valves would adjust their opening position (open more/close more), reducing or increasing fluid flow to and through the respective fluid coils: Reheat and AC valves are controlled in the same manner with opposite effect: for example, when AC valve opens 10% more, Reheat valve closes 10% more etc. if more heat is required by the room air, the Reheat valve opens more, and AC valve closes more, thus diverting more fluid to the reheat coils (heat is rejected to the premise); if more cooling is required by the room air, the AC valve opens more, and Reheat valve closes more, ...
