WLHP Water Loop Heat Pump System

Clivet's WLHP (Water Loop Heat Pump) is widely used in shopping centers, office buildings, hotels and in the most different climatic conditions. Clivet has developed and improved these solutions over the years, even acquiring the English VERSATEMP brand.

The system is based on a hydraulic circuit (ring/loop).The water flows pushed by pumps and in typically "neutral" conditions with refernce to the environment (20-30°C), which acts as a source for energy producers formed by water-air or water-water heat pumps The loop circuit allows efficient transfer of energy between zones with opposite needs (heating/cooling) and activates the dispertion or integration systems only when the temperature of the water tends to stray from the optimal operational interval.

The WSHP system (Water Source Heat Pump), system variation of WLHP, is based on heat pumps which use sea/river or lake water as a renewable energy source. The heat pumps are connected to one another by one or more closed loop circuits with energy transfer and provide the cooling or heating capacity needed to maintain the desired comfort conditions


 


Why to choose WLHP Solution

DECENTRALIZATION WITH ENERGY TRANSFER

The heating or cooling energy required for air conditioning is produced locally in each served area by a free flow between areas with different climatic needs, using only two pipes with water at neutral temperature as exchange fluid. The overall reliability of the system is also increased because a passive failure of one unit does not affect the other ones.

REDUCED INITIAL INVESTMENT

The investor can transfer much of the initial plant cost to individual consumers, enabling the individual regulation of a single system by the owners. Even the energy metering is immediate and charged to the individual user. The packaged units of the system do not require any complex on-site operations and therefore the time spent on assembly and testing is reduced, simplifying the organization of the construction site.

ENLARGEABLE IN TIME

The number of units connected to the system is virtually unlimited, and the system can be easily expanded in the future. Even the pipes do not have length limits, do not require insulation, can be plastic and above all contain water at a neutral instead of chilled temperature. This lowers the cost for the mandatory inspections required by the European F-Gas regulations that limit the leakage of refrigerant fluids, already applied everywhere in Northern Europe. The high efficiency of the system also reduces its environmental impact and greenhouse effect.

A RANGE OF EFFICIENT AND COMPLETE PRODUCTS

A range from 1 to 350 kW specialized for application, assures high energy efficiency, with COP up to 5,9. Over 300 applications in commercial galleries, office buildings, hotels, public buildings shows the WLHP reduction of seasonal consumptions up to 50%.

The system's elements

Packaged Versatemp units for small and medium surfaces

Packaged Versatemp CHV-X, CRH-XHE2, EVH-X, EVH-S, EVH Space, EQV-X units generate locally and in a highly efficient way the thermal and cooled energy required to satisfy the requirements of small and large environments. They purify the air therein through continuous filtration.


Roof Top units for large surfaces

Rooftop packaged units CRH-XHE2 are also suitable for supplying the necessary change of air, with the possibility of carrying out energy recovery.


Fresh air: ZEPHIR3

ZEPHIR3 supplies the necessary air renewal, filters the air through H10 equivalent efficiency electronic filters, and actively contributes to air conditioning the served area.
