20140260381 | USER CONTROL INTERFACE FOR HEAT TRANSFER SYSTEM - A controller can be connected to a heat transfer system including pressure and temperature sensors, an electrically controlled valve, and a compressor. The controller can be configured to control the heat transfer system according to compressor suction superheat, compressor discharge superheat, compressor suction pressure, compressor discharge pressure, and temperature of water received at a condenser to be heated by waste-heat bearing fluid in an evaporator. The controller can include a touchscreen configured to display a user control interface configured to display views based on a permissions database defining different types of users. The views can include different views having different input fields, output fields, and output graphs. The permissions database can permit input of control loop parameters by one of the different types of users and prevent input of control loop parameters by another of the different types of users. | 09-18-2014 |
20140260380 | COMPRESSOR CONTROL FOR HEAT TRANSFER SYSTEM - A compressor is connected with an evaporator, a condenser, and an electrically controlled valve for circulating a working fluid in a system for recovering waste heat to provide heated water. A controller can be configured to adjust an operating capacity of the compressor to maintain output of a condenser temperature sensor at a condenser temperature set point, except when output of a compressor discharge pressure sensor indicates that a maximum operating pressure of the compressor has been exceeded. In such case the controller reduces the operating capacity of the compressor. The controller may further be configured to shut down the compressor when the discharge pressure sensor indicates that a shutdown pressure has been exceeded. | 09-18-2014 |
20140026608 | RETRO-FIT ENERGY EXCHANGE SYSTEM FOR TRANSPARENT INCORPORATION INTO A PLURALITY OF EXISTING ENERGY TRANSFER SYSTEMS - A condenser with subcooling is provided. The condenser comprises apparatus for collecting liquid refrigerant and increasing a velocity of the liquid refrigerant as the liquid refrigerant interfaces with at least one wall of a first pass liquid medium compartment, thereby removing heat from the liquid refrigerant, subcooling the liquid refrigerant and heating a liquid medium. | 01-30-2014 |
20130037249 | RETRO-FIT ENERGY EXCHANGE SYSTEM FOR TRANSPARENT INCORPORATION INTO A PLURALITY OF EXISTING ENERGY TRANSFER SYSTEMS - A controller connectable to a plurality of energy sources, energy demands and energy transfer units is contemplated. The controller is configurable to dynamically route excess energy from different sources to different demands via the energy transfer unit(s). | 02-14-2013 |
20130031933 | RETRO-FIT ENERGY EXCHANGE SYSTEM FOR TRANSPARENT INCORPORATION INTO A PLURALITY OF EXISTING ENERGY TRANSFER SYSTEMS - A controller connectable to a plurality of energy sources, energy demands and energy transfer units is contemplated. The controller is configurable to dynamically route excess energy from different sources to different demands via the energy transfer unit(s). | 02-07-2013 |
