ABSTRACT

During the period July 2001 to March 2002, the performance of a water-jacketed high intensity discharge lamp of advanced design was evaluated within a lamp test stand at The University of Arizona (UA), Controlled Environment Agriculture Center (CEAC) in Tucson, Arizona. The lamps and test stand system were developed by Mr. Phil Sadler of Sadler Machine Company, Tempe, Arizona, and supported by a Space Act Agreement between NASA-Johnson Space Center (JSC) and UA. The purpose was for long term testing of the prototype lamp and demonstration of an improved procedure for use of water-jacketed lamps for plant production within the close confines of controlled environment facilities envisioned by NASA within Bioregenerative Life Support Systems. The lamp test stand consisted of six, 400 watt water-cooled, high pressure sodium HID lamps, mounted within a framework. A nutrient delivery system consisting of nutrient film technique re-circulation troughs and a storage tank was also included, but plants grown in the system were not evaluated in this time period. The performance of the lamps was quantified in terms of photosynthetic photon flux (PPF), and spectral irradiance during the 9-month testing period. In addition, an energy balance and a series of short term tests were completed on the lamp system. The lamps were operated on a 16 hour ‘on’ and 8 hour ‘off’ duty cycle each day. The total operation time for the lamps during the test period was 4208 hour. The following report describes a series of tests performed on the water-cooled high pressure sodium (HPS) lamp system.

INTRODUCTION

During the period July 2001 to March 2002, the performance of the Sadler water-jacketed high intensity discharge lamp was evaluated within a lamp test stand at

The University of Arizona (UA), Controlled Environment Agriculture Center (CEAC) in Tucson, Arizona. The lamps and test stand system were developed and constructed by Mr. Phil Sadler of Sadler Machine Company, Tempe, Arizona, and supported by a Space Act Agreement between NASA-Johnson Space Center (JSC) and UA. The lamp test stand and nutrient delivery system were utilized for demonstrating an improved procedure for use of water-jacketed lamps for plant production within the close confines of controlled environment facilities envisioned by NASA within Bioregenerative Life Support Systems. The lamp test stand consisted of six, 400 watt water-cooled, high pressure sodium HID lamps, mounted within a framework (Figure 1). A nutrient delivery system consisting of nutrient film technique re-circulation troughs and a storage tank was also included, but plants grown in the system were not evaluated in this time period. The unique physical and operational characteristics of the Sadler Water-Jacketed Lamp provided distinct advantages over other existing water-jacketed lamps. The quartz annulus has no seals that could degrade and potentially leak. The glass water jacket is not fused to the bulb, and it is not discarded when the commercially available HID bulb fails. In addition, the lamp is compact and has a horizontal orientation, allowing for a reduced vertical profile. Previous studies have illustrated alternative designs to remove heat with water jackets (Davis, 1994).

The following report describes a series of tests performed with the water-cooled high pressure sodium (HPS) lamp system. The primary purpose of these tests was to quantify and document the performance of the water-cooled lamps during long term operation.
