  • Hvac System Covid Procedures
    HVAC SYSTEM COVID PROCEDURES August 17, 2020 Prepared by: Johnson Roberts Associates 15 Properzi Way Somerville, MA 02143 Prepared for: City of Cambridge Executive Summary The HVAC COVID procedures are a compilation of Industry Standards and CDC recommendations. However, it should be noted that good PPE (personal protective equipment), social distancing, hand washing/hygiene, and surface cleaning and disinfection strategies should be performed with HVAC system measures, as studies have shown that diseases are easily transmitted via direct person to person contact, contact from inanimate objects (e.g. room furniture, door and door knob surfaces) and through hand to mucous membrane (e.g. those in nose, mouth and eyes) contact than through aerosol transmission via a building’s HVAC system. Prior to re-occupying buildings, it is recommended that existing building HVAC systems are evaluated to ensure the HVAC system is in proper working order and to determine if the existing system or its associated control operation can be modified as part of a HVAC system mitigation strategy. Any identified deficiencies should be repaired and corrected, and if the building HVAC system is a good candidate for modifications those measures should be implemented. In general HVAC system mitigation strategies should include the following recommendations: 1. Increase Outdoor Air. The OA increase must be within Unit's capacity in order to provide adequate heating or cooling so Thermal Comfort is not negatively impacted. Also use caution when increasing OA in polluted areas (e.g. High Traffic/City areas) and during times of high pollen counts. 2. Disable Demand Control Ventilation where present.

March 2006 ABSTRACT A review ofpast research reveals that while exergetic analysis has been performed on various building mechanical systems, there has not been extensive efforts in the areas of air distribution systems or cooling plants. Motivations for this new work include demonstrating the merits of exergetic analysis in association with retrocommissioning (RCX) an existing building air handling unit (AHU), as well as conducting an advanced analysis on an existing chiller.

  • Energy Savings and Collateral Impacts of a DHW Water-To-Water Heat Pump System with Subslab Earth Coupling
    Energy Savings and Collateral Impacts of a DHW Water-to-Water Heat Pump System with Subslab Earth Coupling William D. Rittelmann, PE Member ASHRAE ABSTRACT This paper presents research results from simulations and a field investigation of a domestic hot water (DHW) system incor- porating a water-to-water heat pump and a subslab earth-coupled loop. The research stems from a need for nonsolar, high-effi- ciency, DHW system alternatives to help reach the whole-house energy savings goals of 50% and higher. A schematic diagram of the system is used to explain the system concept, emphasizing daily average DHW loads and the resulting load density imposed on the slab. A comparison to air-to-water heat pumps summarizes the primary advantages and market barriers of this system type. A summary of the analysis using a transient system simulation model is reviewed, and sensitivity to key system parameters and user schedules is discussed. The relative importance of subhourly simulation time steps and hot water demand schedules is explained. Collateral energy impacts of individual system components are then presented on monthly and annual bases and compared to results from a base-case simulation incorporating a conventional electric resistance water heater. Additional or reduced heat flux through the slab and standby tank losses/gains are of particular interest, as are variations due to foundation type and climate. The calculation of the net whole-house coefficient of performance is explained and total annual energy consump- tion is presented. INTRODUCTION still has a source-energy factor of 0.83, and an HPWH drops Domestic hot water (DHW) energy use accounts for an to only 0.72.

Description Electro-mechanical, low-temperature limit/cut-out thermostat with a 20 ft, 10 ft or 6 ft capillary sensing element, auto- or manual reset, and 1-SPDT or 2-SPDT switched output. Applications The thermostat and its capillary sensing element provide an antifreeze function. It detects temperature drops below a fixed safety value (setpoint), i.e. heaters in A/C units, exchangers in cooling systems, etc. Operation Any 1-foot length of the sensing element subjected to temperatures below the low cut-out setpoint setting of the thermostat will actuate the thermostat switch mechanism regardless of the temperature being sensed by the remainder of the element. The low cut-out setpoint is factory set and can be adjusted by turning the slotted screw on top of the enclosure. NOTICE: The Freeze Thermostat is factory set at 39°F. This is the ideal setting that will provide the best protection while avoiding nuisance trips. Auto-reset types will automatically switch back to the normal position if the temperature returns to normal conditions. Manual-reset types will switch back only if both the temperature returns to normal conditions and the reset button (at the enclosure’s front) is manually pushed. Wiring All wiring should comply with National and Local Electrical Codes. A M20 watertight fitting is installed in the ½” conduit knockout.

  • British Engine Boiler Insurance Company Limited
    British Engine, Boiler and Electrical Insurance Company Limited, 1878- 1991 Location and extent of archival material: SS4/2-8, 57 boxes The listing has been completed in box number order and there has been no attempt to arrange material into series as the collection simply includes a large selection of miscellaneous company catalogues. Company history The Company was founded in Manchester on November 12 1878 under the title of ‘The Engine and Boiler Insurance Company’ with RB Longridge as Chairman and Micheal Longridge (his nephew) as Chief Engineer. The Longridge family were established engineers at the beginning of the 19th Century. They were originally iron masters of Bedlington, Northumberland who also supplied castings and forgings to the engineers of the day. They were involved in the early development of industrial steam engines and were business partners with both George and Robert Stephenson. Members of the Longridge family continued to serve the Insurance Company from the early days until the introduction of nuclear power. RB Longridge formed The Steam Boiler Assurance Company in 1859 but later resigned. Following his resignation he formed ‘The Engine and Boiler Insurance Company Limited’. Within two years the name changed to ‘The Engine, Boiler and Employers’ Liability Company Limited’. In 1903, the Silver Jubilee year the title ‘British Engine, Boiler and Electrical Insurance Company Limited’ was adopted, and in 1978 the title was abbreviated to ‘British Engine Insurance Limited’. The family association terminated in 1966 with the retirement of HM Longridge. The name of Longridge was perpetuated in the title of the Head Office building in Manchester- Longridge House, erected in 1959 on a site embracing that of the original Manchester Steam Users Association of which RB Longridge was Chief Inspector.
