Humidification System with Pressure Condensate Return and Method Therefor
Supplied humidification steam is dispersed through tubes and a header. Condensate is collected from the header into a tank. A controlled steam supply valve pumps condensate from the tank to a return line by application of sourced steam. A non-mechanical electronic level sensor (ELS, sensing temperature, resistance, capacitance, inductance, luminance or sonic condition of condensate) signals a controller using the ELS and/or a timed pumping/evacuation cycle to push condensate from the tank to the return. The method removes condensate by isolating the collection tank from the tubes and header and pumps condensate from the tank based upon a sensed conditions.

Water condenser
A water condenser includes a fan which draws a primary airflow through an upstream refrigerant evaporator, through an air-to-air heat exchanger and in one embodiment also an air-to-water heat exchanger uses cold water collected as condensate from the evaporator, the airflow to the evaporator being pre-cooled by passing through the air-to-air heat exchanger and the air-to-water heat exchanger prior to entry into the evaporator wherein the airflow is further cooled to below its dew point so as to condense moisture onto the evaporator far gravity collection. The evaporator is cooled by a closed refrigerant circuit. The refrigerant condenser for the closed refrigerant circuit may employ the fan drawing the airflow through the evaporator or a separate fan, both of which drawing an auxiliary airflow separate from the airflow through the evaporator through a manifold whereby bath the auxiliary airflow and the airflow through the evaporator, or just the auxiliary airflow are guided through the condenser and corresponding fan.

Vacuum system having condenser and root vacuum pump set
A vacuum system has a condenser and a root vacuum pump set, wherein the condenser is an independent inlet condenser set connected to a generator including an air cooling power generator condenser. A pressure sensor is installed on the independent inlet condenser set for detecting a first input pressure. Air outputted from the independent inlet condenser set is compressed by the root vacuum pump set. A backing pump receives an air outputted from the root vacuum pump set through an output pipe. A bypass pipe is connected between an output end of the root vacuum pump set and a vapor-liquid separator connected to the backing pump. A central controller serves to receive the first input pressure and determine to control the air from the root vacuum pump set to be outputted to the output pipe or the bypass pipe by a control valve.
