Water-Loop Heat Pump Systems: Latvian Experience

Today most modern buildings in the world widely use the systems of heating, ventilation and air conditioning (HVAC) in order to create and maintain a microclimate in the rooms corresponding to the required norms. One of the most update HVAC systems is the water loop heat pump (WLHP-system). The engineering systems of the complex „Riga Plaza”, including the systems of heating, conditioning and air preparation are divided into several independent parts each of which corresponds by its characteristics to a particular functional area of the complex. The source of the heat supply of the complex is a gas boiler house. The sources of cold are twelve chillers and twelve dry cooling towers installed in the utility rooms on the roof of the building as well as on a special site next to the building of the complex
