Also, the interest in low GWP chiller is increasing, due to the important environmental problem. We have developed refrigeration and heat pump systems using an eco-friendly refrigerant, water. Considering the large specific volume and surface tension of the water, we designed heat exchangers and the compressors. We first performed lab scale experiments of the components and decided the design parameters for the final prototype. We manufactured the prototype and tested the performance. Here, we show the performance with the manufacturing process. Moreover, we introduce several other ongoing projects related to eco-friendly heat pump systems.<span style="border: 0px; font: inherit; margin: 0px; padding: 0px; vertical-align: baseline; color: rgb(31, 73, 125);"></span></span></p><p class="x_MsoNormal" style="margin: 0cm 0cm 0.0001pt; font-size: 10pt; font-family: &quot;맑은 고딕&quot;; text-align: justify; color: rgb(36, 36, 36); background-color: rgb(255, 255, 255);"><span lang="EN-US" style="border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; font-size: inherit; font-family: 나눔고딕, serif, EmojiFont; font-optical-sizing: inherit; font-kerning: inherit; font-feature-settings: inherit; font-variation-settings: inherit; margin: 0px; padding: 0px; vertical-align: baseline; color: rgb(31, 73, 125);">&nbsp;</span></p>
