Hava kaynaklı ısı pompalarının soğuk iklim bölgelerinde kullanımı için önerilen tasarım ve modifikasyonlar
Dış sıcaklıkların düşük olduğu zamanlarda elde edilen ısının ve COP'un düşük olması, hava kaynaklı ısı pompalarının soğuk iklim bölgelerinde kullanılmasını sınırlamaktadır. Soğuk İklimlerde soğutma dizayn yüklerinin ısıtma dizayn yüklerinden küçük olması sonucu ısı pompaları, ya ısıtma için küçük boyutlandırılmış (ilave ısıtma gerekli) veya soğutma için büyük boyutlandırılmış olur. Ayrıca, dış hava sıcaklığı azaldığında, kompresörde olan sıcaklık artışının yükselmesi nedeniyle ısıtma çevrimi verimi azalır. Bu güçlükleri ortadan kaldırmak amacıyla ısı pompaları için çeşitli dizayn modifikasyonları ve teknolojileri önerilmiş ve uygulanmıştır. Bu makalede, hava kaynaklı ısı pompalarının soğuk iklim bölgelerinde kullanımı için önerilen tasarım ve modifikasyonlar incelenmiştir.
Use of air source heat pumps is limited in cold climates due to lower heating capacity and COP at lower ambient temperature conditions. Since cooling design loads are smaller than the heating design loads in cold climates, heat pumps are small sized for heating (backup heating required) or oversized for cooling. In addition, as ambient temperature decreases, heating cycle efficieny decreases due to higher temperature lift. To overcome such difficulties various design modifications and technologies have been suggested and applied. Design and modification suggestions for air source heat pumps in cold climates are studied in this paper.
