Method for providing positive pressure to an interior of a positive pressure facility

摘要

A method for providing positive pressure to an interior of a positive pressure facility can use an HVAC system. The method can include securing an enclosure to an exterior of the positive pressure facility, pulling fresh air from outside of the enclosure into an evaporator compartment to form conditioned air, transferring the conditioned air from the enclosure to an enclosure extension attached to the interior, and flowing the conditioned air into the interior. The method can include receiving air from the interior into the enclosure extension, determining a differential pressure between a pressure outside and a pressure of the interior, and maintaining positive pressure in the interior using the differential pressure, a process control unit, the conditioned air, and a human machine interface. The human machine interface can determine present various real-time values, control buttons, and screens for operating the HVAC system.

1. A method for providing positive pressure to an interior of a positive pressure facility using a modular heating, ventilation, and air conditioning system, wherein the method comprises:
a. securing an enclosure to an exterior of the positive pressure facility and connecting to a power supply, wherein the enclosure comprises:
(i) a base;(ii) a condenser compartment mounted to the base, wherein the condenser compartment comprises an air venturi for pulling air across a condenser coil in the condenser compartment;(iii) an evaporator motor compartment connected with the condenser compartment;(iv) an evaporator compartment connected with the evaporator motor compartment with an evaporator compartment drain;(v) a compressor compartment connected with the evaporator motor compartment; and(vi) a heater compartment adjacent the compressor compartment for heating fresh air from outside of the enclosure; b. pulling the fresh air from outside of the enclosure into the evaporator compartment to form conditioned air; c. transferring the conditioned air from the enclosure to an enclosure extension attached to an interior of the positive pressure facility; d. flowing the conditioned air into the interior of the positive pressure facility; e. receiving air from the interior of the positive pressure facility into the enclosure extension; f. determining a differential pressure between a pressure outside of the positive pressure facility and a pressure of the interior of the positive pressure facility; and g. maintaining positive pressure in the interior of the positive pressure facility using the determined differential pressure, a process control unit, the conditioned air, and a human machine interface connected with the process control unit, wherein the human machine interface and the process control unit perform the steps of:
(i) determining real-time temperature values and presenting the real-time temperature values on a display;(ii) determining real-time humidity values and presenting the real-time humidity values on the display;(iii) determining real-time building pressure and presenting the real-time building pressure on the display;(iv) presenting a home control button on the display;(v) presenting a control button on the display;(vi) presenting a health control button on the display;(vii) presenting a set points control button on the display;(viii) presenting a values control button on the display;(ix) presenting a heating, cooling, and dehumidifying indicator on the display;(x) presenting an operating indicator on the display;(xi) presenting a building pressure OK indicator on the display;(xii) presenting a system OK alarm on the display; and(xiii) presenting a time.
