container--no-margin\">\n<p class=\"wp-block-paragraph \">The condominium was served by a centralized system based on three old gas boilers and radiators for heating and domestic hot water production and two large chillers with cooling towers installed on the roof, combined with fan coils.<\/p>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<p class=\"wp-block-paragraph \">To meet the challenge, interventions were made both on the building envelope, providing the condo with thermal insulation and replacing the old window with low-transmission windows; and on the heating and air-conditioning system, replacing the existing system with a complete hybrid system made by Clivet. The existing radiators, fancoils, and internal regulation and metering system were maintained.<\/p>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<p class=\"wp-block-paragraph \">The new installed system consists of:<\/p>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<ul class=\"wp-block-list\">\n<li>6 ELFOEnergy Magnum WASN-XIN polyvalent heat pumps of 80kW, each capable of producing hot and chilled water simultaneously<\/li>\n\n\n\n<li>6 boilers of 200 kW<\/li>\n\n\n\n<li>2 ELFOEnergy Ground Medium WSHH-LEE1 100 kW high temperature water-to-water heat pumps<\/li>\n\n\n\n<li>3 x 2000l storage tanks for summer cooling<\/li>\n\n\n\n<li>2 x 2000l storage tanks for heating<\/li>\n\n\n\n<li>2 x 2500l storage tanks for DHW, each equipped with two exchangers, which exchange respectively with the high temperature water-water HPs and the boilers, which only intervene in the event of greater demand<\/li>\n\n\n\n<li>1 Clivet Intelliplant management system<\/li>\n<\/ul>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<p class=\"wp-block-paragraph \">The six multi-purpose HPs produce the hot water for the storage tanks, which act as a source to serve the high temperature HPs. During most of the year, when there is a similar demand for heating and cooling, hot and cool water can be produced simultaneously and hihgly efficiently.<\/p>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<p class=\"wp-block-paragraph \">DHW is produced by using the hot water of the mutlifuntional HPs, thus not using \u2018outside\u2019 water. Taking advantage of the multifunctional technology, combined with high temperature HPs, it is also possible to produce domestic hot water at temperatures above 65\u00b0C without using a boiler. The system is completed with six boilers which can work in integration in the case of high heating demands, or in total replacement in the case of heat pump maintenance.<\/p>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<p class=\"wp-block-paragraph \">The entire AC-system is managed by the Clivet Intelliplant supervision system, which coordinates the entire thermo-cooling plant, enabling the central resources according to the requests received from the individual flats and always activating the most efficient resource (while favoring the use of heat pumps). Due to this system it is possible to run heat pumps in combination with boilers, thus providing a perfectly reliable and efficient hybrid system for every eventuality. It allows the consumer to monitor thermal, cooling and electrival consumption. <\/p>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<p class=\"wp-block-paragraph \">Pictures: Via Cervignano (Milano-Italy) Clivet S.p.A.<\/p>\n<\/div>\n\n\n<div class=\"wp-block-group is-layout-constrained wp-block-group-is-layout-constrained\"><div class=\"container container--no-margin\">\n<div class=\"wp-block-buttons is-horizontal is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-b989473c wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button has-custom-width wp-block-button__width-50 has-custom-font-size is-style-outline has-medium-font-size is-style-outline--1\" style=\"text-transform:none\"><a class=\"wp-block-button__link has-vivid-cyan-blue-color has-white-background-color has-text-color has-background has-text-align-center wp-element-button\" href=\"https:\/\/heatpumpingtechnologies.org\/content\/uploads\/sites\/75\/2024\/04\/it005fact-sheet-milano-via-cervignano.pdf\" style=\"border-radius:5px\" target=\"_blank\" rel=\"noreferrer noopener\"><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"84\" class=\"wp-image-2196\" style=\"width: 300px;\" src=\"https:\/\/heatpumpingtechnologies.org\/content\/uploads\/sites\/75\/2024\/02\/fact-sheet-button-pic.png\" alt=\"\" srcset=\"https:\/\/heatpumpingtechnologies.org\/content\/uploads\/sites\/75\/2024\/02\/fact-sheet-button-pic.png 845w, https:\/\/heatpumpingtechnologies.org\/content\/uploads\/sites\/75\/2024\/02\/fact-sheet-button-pic-300x84.png 300w, https:\/\/heatpumpingtechnologies.org\/content\/uploads\/sites\/75\/2024\/02\/fact-sheet-button-pic-768x215.png 768w, https:\/\/heatpumpingtechnologies.org\/content\/uploads\/sites\/75\/2024\/02\/fact-sheet-button-pic-400x112.png 400w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/> <\/a><\/div>\n<\/div>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<p class=\"has-text-align-center wp-block-paragraph \">IT005 Via Cervignano&nbsp; <\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Via Cervignano, Milan Refurbishment of an existing building: This project oversaw the energy requalification of a 107-apartment condo &#8211; from&#8230;<\/p>\n","protected":false},"author":41,"featured_media":0,"menu_order":0,"template":"","filters":[],"markets":[25],"applications":[7,41],"class_list":["post-2564","case_studies","type-case_studies","status-publish","hentry","markets-italy","applications-buildings","applications-multi-family-buildings"],"acf":[],"_links":{"self":[{"href":"https:\/\/heatpumpingtechnologies.org\/project62\/wp-json\/wp\/v2\/case_studies\/2564","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/heatpumpingtechnologies.org\/project62\/wp-json\/wp\/v2\/case_studies"}],"about":[{"href":"https:\/\/heatpumpingtechnologies.org\/project62\/wp-json\/wp\/v2\/types\/case_studies"}],"author":[{"embeddable":true,"href":"https:\/\/heatpumpingtechnologies.org\/project62\/wp-json\/wp\/v2\/users\/41"}],"version-history":[{"count":5,"href":"https:\/\/heatpumpingtechnologies.org\/project62\/wp-json\/wp\/v2\/case_studies\/2564\/revisions"}],"predecessor-version":[{"id":2576,"href":"https:\/\/heatpumpingtechnologies.org\/project62\/wp-json\/wp\/v2\/case_studies\/2564\/revisions\/2576"}],"wp:attachment":[{"href":"https:\/\/heatpumpingtechnologies.org\/project62\/wp-json\/wp\/v2\/media?parent=2564"}],"wp:term":[{"taxonomy":"filters","embeddable":true,"href":"https:\/\/heatpumpingtechnologies.org\/project62\/wp-json\/wp\/v2\/filters?post=2564"},{"taxonomy":"markets","embeddable":true,"href":"https:\/\/heatpumpingtechnologies.org\/project62\/wp-json\/wp\/v2\/markets?post=2564"},{"taxonomy":"applications","embeddable":true,"href":"https:\/\/heatpumpingtechnologies.org\/project62\/wp-json\/wp\/v2\/applications?post=2564"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
