Abstract: A ventilation system for an air conditioning system includes dampers, a heat exchange unit, and a control unit. One damper controls the flow of ambient air into the system. The other damper controls the flow of relief/exhaust air that is utilized to scavenge energy from return air from a room or space being cooled (or heated) by the air conditioning system. The ventilation system utilizes a control algorithm in the control unit to calculate, at stepped spaced apart increasing room ventilation rates, increasing CO2 concentrations in the air in the room that are below a maximum desired CO2 concentration in a room. The control algorithm permits a control unit in the ventilation system to open and close the dampers to maintain a CO2 concentration in the room that is below the desired CO2 concentration level.

Abstract: The present disclosure belongs to the technical field of farm irrigation, and particularly relates to a novel pressureless irrigation device. The novel pressureless irrigation device of the present disclosure uniformly conveys irrigation water to crop plant root systems on the basis of a “connector” principle; and the size of a flow cross-section necessarily satisfies the extremely-low flowing speed requirement of “lossless conveyance” for the “connector” in a static pressure dominant operating state, thereby eliminating a problem of irrigator blockage which accompanies energy dissipation. Water enters the atmosphere via transpiration of crop plants, and a water supply water level control pool at a head portion is triggered to replenish the water. The water consumption and water replenishment are adaptive, and human intervention and additional energy are not required, thereby realizing low-cost and “fool-proof” automatic irrigation and true sense of uniform irrigation.

Abstract: A valve-closing pressure chamber and a valve-opening pressure chamber are arranged on both sides of a main diaphragm inside an outlet shutoff valve. An upper supply/discharge tube and a lower supply/discharge tube are connected to a housing forming the outlet shutoff valve.
