50VQ Vertical Standard & Low-Temperature Water Source Heat Pump Unit Features
- Available in 17 sizes for application flexibility
- Designed for high-efficiency year-round cooling and heating
- Ideal for schools, offices, apartments, hotels/motels, and condominiums
- Utilizes decentralized concept, which allows individual tenant
metering, low initial cost, and control flexibility
- Choices of heat exchangers allow use in closed-loop or open-loop
applications
- Standard operating temperatures with a minimum entering water
temperature of 60-degrees (F) and a minimum entering air temperature of 50-degrees
(F) in the heating mode
- Low temperature model offers operating temperatures with a minimum
entering water temperature of 40-degrees (F) and a minimum entering air temperature
of 40-degrees (F) in the heating mode
- Carrier water source heat pumps (WSHP) are designed for quality
and performance excellence over their life-time. Capacities range from 3/4-ton to
25-tons. Models offer cooling EERs (Energy Efficiency Ratio) to 12.2, and heating
COPs (Coefficient of Performance) to 4.5, which are among the highest in the industry.
- Fan motors and compressors are sound isolated, and the insulated
cabinet makes unit operation even quieter. Standard safety features include: high-pressure
switch, freeze protection switches, and loss-of-charge protection which consists
of either a low pressure switch or a high discharge temperature switch. Each unit
is tested and run at the factory to assure proper operation of all components and
safety switches. All components are carefully de-signed and selected for endurance,
durability, and carefree day-to-day operation. The water-to-refrigerant heat exchanger
has copper inner and steel outer tubing to provide corrosion resistance protection.
Cupronickel heat exchangers are available for open tower applications. The unit is
shipped on a protective wooden skid with rigid corner posts held in place by plastic
stretch wrap. Units are ARI (Air Conditioning & Refrigeration Institute) Standard
320-93 certified and UL (Underwriters' Laboratories) and CSA (Canadian Standards
Association) listed (575 v CSA only).
- The electromechanical (Weather-Source) control system provides
control of the unit's compressor, reversing valve, fan, safety lockout, and re-mote
LED (light-emitting diode) fault indication from a conventional wall-mounted thermostat.
Program/night setback relay accepts a 24-v signal from a centrally located time clock
which establishes occupied/unoccupied time periods for added energy savings.
