System and method to maintain evaporator superheat during pumped refrigerant economizer operation

The present disclosure relates to a method for controlling a level of superheat during a pump mode of operation of a refrigeration system, wherein the refrigeration system can operate in either the pump mode or a compressor mode, and has an electronically controlled expansion valve (EEV). A controller obtains a... Liebert Corporation

Fin and tube-evaporator with mini-slab circuit extenders

An evaporator for a cooling system has a slab coil having a plurality of refrigerant circuits with each refrigerant circuit being a fin-and-tube assembly that extends across the slab coil. At least one of the refrigerant circuits has a mini-slab circuit extender that has a fin-and-tube assembly that extends across... Liebert Corporation

Method to reduce inrush currents in a transformer-less rectifier uninterruptible power supply system

A method reduces inrush currents in a transformer-less rectifier UPS system when an input circuit breaker of the UPS system is closed from an open position. The circuit breaker is coupled between an AC power input and an AC input of a rectifier of the UPS system and a DC... Liebert Corporation

Systems and methods for detecting degradation of a component in an air conditioning system

A method including: determining whether a cooling system is operating in a cooling mode, such that the cooling system is not operating in a reheat mode, a humidification mode or a dehumidification mode; determining whether the cooling system is operating in a compressor mode, such that the cooling system is... Liebert Corporation

Hybrid air handler cooling unit with bi-modal heat exchanger

A hybrid air handler cooling unit has a bi-modal heat exchanger. In a direct expansion mode or a pumped refrigerant economization mode, the bi-modal heat exchanger is in a refrigerant path in parallel with first and second condenser coils and functions as a condenser coil. In a mixed direct expansion/pumped... Liebert Corporation

Cooling system for high density heat loads

A pumped refrigerant cooling system having multiple pumping units for providing working fluid to a load to enable cooling of a space via the load. The pumped refrigerant cooling system operates the pumping units at less than capacity. When a pumping unit is deactivated, the output of the remaining pumping... Liebert Corporation

System and rapid input and configuration of sensors for a hvac monitoring system

The present disclosure relates to a processor based system for using temperature information being reported by a plurality of sensors present within a predetermined environment and controlling how various ones of the sensors are grouped together into a plurality of groups for monitoring purposes. The system includes a software subsystem... Liebert Corporation

Cooling systems for small equipment rooms and methods of cooling small equipment rooms

A cooling system for an equipment closet in a building has a direct expansion cooling circuit. The cooling system has two basic modes of operation. A first mode where the direct expansion cooling circuit is off and transfer air from an area of the building outside the equipment closet is... Liebert Corporation

Pumped refrigerant cooling system with 1+1 to n+1 and built-in redundancy

A pumped refrigerant cooling system having cooling units with associated pumping units for providing working fluid to the cooling unit to enable cooling of a space. The pumped refrigerant cooling system also includes a redundant pumping unit which is activated when a primary pumping unit associated with a cooling unit... Liebert Corporation

System and modular data center

The present disclosure relates to a unit structure for use in forming a modular data center. The unit structure may have an elongated frame structure forming a rectangular-like subsystem, and may be adapted to be supported above a floor surface. At least one conduit may be integrated into the elongated... Liebert Corporation
