    摘要： An evaporative HVAC apparatus is disclosed. In at least one embodiment, the apparatus provides an at least one absorbent wicking layer having a first surface and an opposing second surface, and an at least one thermal layer also having a first surface and an opposing second surface. The second surface of the at least one thermal layer is formed immediately adjacent to the first surface of the at least one wicking layer. An at least one fluid line is in fluid communication with the at least one wicking layer. Thus, a fluid is selectively delivered to the wicking layer through the at least one fluid line which, in turn, permeates the at least one thermal layer and evaporates into the air located immediately adjacent the exposed first surface of the at least one thermal layer, thereby affecting the temperature of the air.

    摘要： Heat transfer pipes 26b1 and 26b2 extend from the other end section 21B to one end section 21A in an intermediate row L2 and combine in the one end section 21A to be heat transfer pipes 26c1 and 26c2. The heat transfer pipes 26c1 and 26c2 are configured to extend back and force once between the one end section 21A and the other end section 21B in a upstream row L1. Heat transfer pipes 26b3 and 26b4 extend from the other end section 21B to the one end section 21A in the intermediate row L2 and combine in the one end section 21A to be heat transfer pipes 26c3 and 26c4. The heat transfer pipes 26c3 and 26c4 are configured to extend back and force once between the one end section 21A and the other end section 21B in the upstream row L1. The heat transfer pipe 26c2 extending from the other end section 21B to the one end section 21A and the heat transfer pipe 26c4 from the other end section 21B to the one end section 21A are arranged to be adjacent to each other.

    摘要： A computer room air conditioner (CRAC) unit includes a housing having an inlet configured to receive IT air and an outlet configured to exhaust treated air. The CRAC unit further includes a heat exchanger supported by the housing and disposed between the inlet and the outlet of the housing and at least one fan module supported by the housing. The at least one fan module is configured to draw IT air into the housing through the inlet, direct IT air through the heat exchanger, and exhaust treated air through the outlet. The CRAC unit further includes an airfoil frame secured to the housing at the inlet of the housing.

    摘要： Methods for providing heating or cooling to a plurality of zones in a conditioned space, include adjusting a temperature of a primary airflow using a heating, ventilation, air conditioning, and refrigeration (HVACR) system including a heat pump circuit and distributing the primary airflow to a plurality of terminals in the zones. The methods further include directing heat from the heat pump circuit to at least one of the plurality of terminals and heating air at the at least one of the plurality of terminals using the heat directed from the heat pump circuit. The methods can further include utilizing sources and sinks of the heat pump circuit to efficiently provide the heating or cooling. Systems include the heat pump circuit, terminals, heat distribution, and can include a controller to operate those components.
