When the control system calls for higher or lower temperature on the air outlet, the PICV opens or closes to increase or decrease the flow through the coil. The power output from the coil follows a parabolic curve where often an EQ% valve\/actuator characteristic is chosen to have a direct relation between the input control signal and power output.<\/p>\n<h3><strong>Benefits<\/strong><\/h3>\n<ul>\n<li>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0The PICV ensures balancing of the primary flow and eliminates the use of both static balancing valves and differential pressure control valves.<\/li>\n<li>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0Simple application as only a PICV is required to control flow, temperature and differential pressure.<\/li>\n<li>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0At part load, the flow through the coil can be low leading to laminar flow and reducing the power output.<\/li>\n<li>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0Larger coils can have different temperatures in different areas of the coil making precise temperature control difficult.<\/li>\n<li>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0A metering station can be installed if additional flow verification is required.<\/li>\n<\/ul>\n<h3><strong>Considerations<\/strong><\/h3>\n<p>[\/vc_column_text][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column width=&#8221;7\/12&#8243;][vc_column_text woodmart_inline=&#8221;no&#8221; text_larger=&#8221;no&#8221;][\/vc_column_text][\/vc_column][vc_column width=&#8221;5\/12&#8243;][vc_column_text woodmart_inline=&#8221;no&#8221; text_larger=&#8221;no&#8221;]Air Handling Unit with PICV direct control Function The air temperature of the Air<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[81],"tags":[],"class_list":["post-1316","post","type-post","status-publish","format-standard","hentry","category-applications"],"_links":{"self":[{"href":"https:\/\/yektatadbirco.ir\/en\/wp-json\/wp\/v2\/posts\/1316","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/yektatadbirco.ir\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/yektatadbirco.ir\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/yektatadbirco.ir\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/yektatadbirco.ir\/en\/wp-json\/wp\/v2\/comments?post=1316"}],"version-history":[{"count":4,"href":"https:\/\/yektatadbirco.ir\/en\/wp-json\/wp\/v2\/posts\/1316\/revisions"}],"predecessor-version":[{"id":1334,"href":"https:\/\/yektatadbirco.ir\/en\/wp-json\/wp\/v2\/posts\/1316\/revisions\/1334"}],"wp:attachment":[{"href":"https:\/\/yektatadbirco.ir\/en\/wp-json\/wp\/v2\/media?parent=1316"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/yektatadbirco.ir\/en\/wp-json\/wp\/v2\/categories?post=1316"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/yektatadbirco.ir\/en\/wp-json\/wp\/v2\/tags?post=1316"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
