If you have an indoor pool you need to do three things; heat your pool water, dehumidify the air in the pool room and warm the air in the pool room.
This would normally mean three separate units for each job but with a Calorex Variheat you perform all three tasks with one unit!
The Calorex Variheat connects to a boiler to provide it with low pressure hot water (LPHW) which it uses to heat the pool water via a heat exchanger but it also sucks in the moist air from the pool room, drys it, then warms it and sends it back again.
A comprehensive system for controlling humidity and air and water heating in an indoor pool environment. It can be configured either horizontally or vertically and the control panel can be remotely positioned. They come complete with heater battery, heat exchanger and built in control panel. A fresh/exhaust air module is also available. An LPHW (Low pressure hot water) feed and ductwork is required for this unit.
These units are specified for heat recovery to air and water and air and pool heating. Units with heat recovery to air only (no heating option) and heat recovery to air and air heating are available upon request. This unique range of equipment maximises energy efficiency to ensure running costs are kept to an absolute minimum. This Variheat system provides an ideal solution for domestic and light-commercial projects incorporating air distribution ductwork.
Automated Package Design
All Calorex Variheat Series 3 units are fully automatic to ensure optimum comfort levels and minimum running costs at all times. The package design of this unique equipment means that extremely compact units can be installed, ready assembled, taking up minimal plant room space. Furthermore, with all sensors and controls integrated, choosing to fit a Variheat Series 3 will save valuable installation time on site.
All Calorex Variheat Series 3 Units Provide:
- Humidity Control
- Pool Hall Air Heating
- Pool Water Heating
- Ventilation
- Pool Hall Air Cooling
- Ultimate Build Flexibility
- Control Panels
- Pool Hall Air Distribution
Humidity Control
Humidity is controlled by an efficient compressor driven heat pump circuit. Moisture is extracted from the warm moist air as it condenses internally and then drained to waste. During this dehumidification process, energy is also stripped from the warm moist air, substantially upgraded and converted to recovered heat. This recovered heat is provided free of charge and distributed into the pool water and/or pool hall air.
Pool Hall Air Heating
The Variheat Series 3 offers much more than efficient humidity control. For optimum comfort levels within the pool hall, it is sensible to heat the internal air. For maximum effectiveness, the Variheat can be built with the inclusion of an air heating facility. This will ensure the heat losses via the pool hall building can be dealt with at all times. Two methods of air heating are available; either an electric element type or an internal Low Pressure Hot Water (LPHW) heat exchanger circuit. Choosing a Variheat with an air heating facility will save time, materials and space associated with alternative heating systems. By using the economy switch, the Air heating and dehumidification circuits can also be switched off to enable only pool water heating (if required).
Pool Water Heating
In addition to the Air Heating facility, a pool water heat exchanger can also be built in to the Variheat Series 3. The high capacity range of heat exchangers fitted to these Variheats ensure the pool water is brought up to temperature quickly. Simple connections are provided for plumbing to a source of primary hot water.
Ventilation
A correct balance of fresh air input and exhausted air from the pool hall will help maintain good internal air quality. If independent ventilation equipment is not proposed, the Variheat Series 3 is available with a Ventilation module option. This module is built on to the Variheat, which means that all pool air handling equipment is housed within the plant room. Small circular spigots are provided for ducting both ‘supply’ and ‘extract’ air flows to the outside atmosphere.
Pool Hall Air Cooling
An optional air cooling facility is available. This utilises external condensing module(s) in conjunction with the Variheat equipment. The Variheat can be factory built to incorporate a refrigerant cooling circuit. Details available upon request.
Ultimate Build Flexibility
Variheat Series 3 units are carefully designed, selected and built specifically to suit the individual requirements of each and every project. Whether a simple or complex plant room layout, this equipment offers complete flexibility across the whole range. Combining these factors with the vast number of air flow configurations available, the Variheat Series 3 clearly offers ultimate flexibility.
