Vapour Absorption Refrigeration Systems Based on Ammonia- Water Pair
Lesson 17 Vapour Absorption Refrigeration Systems Based On Ammonia- Water Pair Version 1 ME, IIT Kharagpur 1 The specific objectives of this lesson are to: 1. Introduce ammonia-water systems (Section 17.1) 2. Explain the working principle of vapour absorption refrigeration systems based on ammonia-water (Section 17.2) 3. Explain the principle of rectification column and dephlegmator (Section 17.3) 4. Present the steady flow analysis of ammonia-water systems (Section 17.4) 5. Discuss the working principle of pumpless absorption refrigeration systems (Section 17.5) 6. Discuss briefly solar energy based sorption refrigeration systems (Section 17.6) 7. Compare compression systems with absorption systems (Section 17.7) At the end of the lecture, the student should be able to: 1. Draw the schematic of a ammonia-water based vapour absorption refrigeration system and explain its working principle 2. Explain the principle of rectification column and dephlegmator using temperature-concentration diagrams 3. Carry out steady flow analysis of absorption systems based on ammonia- water 4. Explain the working principle of Platen-Munter’s system 5. List solar energy driven sorption refrigeration systems 6. Compare vapour compression systems with vapour absorption systems 17.1. Introduction Vapour absorption refrigeration system based on ammonia-water is one of the oldest refrigeration systems. As mentioned earlier, in this system ammonia is used as refrigerant and water is used as absorbent. Since the boiling point temperature difference between ammonia and water is not very high, both ammonia and water are generated from the solution in the generator. Since presence of large amount of water in refrigerant circuit is detrimental to system performance, rectification of the generated vapour is carried out using a rectification column and a dephlegmator. -
Chapter 8 and 9 – Energy Balances
CBE2124, Levicky Chapter 8 and 9 – Energy Balances Reference States . Recall that enthalpy and internal energy are always defined relative to a reference state (Chapter 7). When solving energy balance problems, it is therefore necessary to define a reference state for each chemical species in the energy balance (the reference state may be predefined if a tabulated set of data is used such as the steam tables). Example . Suppose water vapor at 300 oC and 5 bar is chosen as a reference state at which Hˆ is defined to be zero. Relative to this state, what is the specific enthalpy of liquid water at 75 oC and 1 bar? What is the specific internal energy of liquid water at 75 oC and 1 bar? (Use Table B. 7). Calculating changes in enthalpy and internal energy. Hˆ and Uˆ are state functions , meaning that their values only depend on the state of the system, and not on the path taken to arrive at that state. IMPORTANT : Given a state A (as characterized by a set of variables such as pressure, temperature, composition) and a state B, the change in enthalpy of the system as it passes from A to B can be calculated along any path that leads from A to B, whether or not the path is the one actually followed. Example . 18 g of liquid water freezes to 18 g of ice while the temperature is held constant at 0 oC and the pressure is held constant at 1 atm. The enthalpy change for the process is measured to be ∆ Hˆ = - 6.01 kJ. -

sustainability Review A Comprehensive Review of Thermal Energy Storage Ioan Sarbu * ID and Calin Sebarchievici Department of Building Services Engineering, Polytechnic University of Timisoara, Piata Victoriei, No. 2A, 300006 Timisoara, Romania; [email protected] * Correspondence: [email protected]; Tel.: +40-256-403-991; Fax: +40-256-403-987 Received: 7 December 2017; Accepted: 10 January 2018; Published: 14 January 2018 Abstract: Thermal energy storage (TES) is a technology that stocks thermal energy by heating or cooling a storage medium so that the stored energy can be used at a later time for heating and cooling applications and power generation. TES systems are used particularly in buildings and in industrial processes. This paper is focused on TES technologies that provide a way of valorizing solar heat and reducing the energy demand of buildings. The principles of several energy storage methods and calculation of storage capacities are described. Sensible heat storage technologies, including water tank, underground, and packed-bed storage methods, are briefly reviewed. Additionally, latent-heat storage systems associated with phase-change materials for use in solar heating/cooling of buildings, solar water heating, heat-pump systems, and concentrating solar power plants as well as thermo-chemical storage are discussed. Finally, cool thermal energy storage is also briefly reviewed and outstanding information on the performance and costs of TES systems are included. Keywords: storage system; phase-change materials; chemical storage; cold storage; performance 1. Introduction Recent projections predict that the primary energy consumption will rise by 48% in 2040 [1]. On the other hand, the depletion of fossil resources in addition to their negative impact on the environment has accelerated the shift toward sustainable energy sources. -

Minimum energy buildings (MEBs) demand as little energy as possible, with an optimized architectural design, which includes passive solutions. In addition, these buildings consume as low energy as possible introducing efficient facilities. Finally, they produce renewable energy on-site to become zero energy buildings (ZEBs) or even plus zero energy buildings (+ZEB). In this paper, a deep analysis of the energy use and renewable energy production of a social dwelling was carried out based on data measurements. Unfortunately, in residential buildings, most renewable energy production occurs at a different time than energy demand. Furthermore, energy storage batteries for these facilities are expensive and require significant maintenance. The present research proposes a strategy, which involves rescheduling energy demand by changing the habits of the occupants in terms of domestic hot water (DHW) consumption, cooking, and washing. -

SOLAR HEATING CONTROLS by Radiantec Company
SOLAR HEATING CONTROLS by Radiantec Company THE SOLAR CONTROL LOOP Solar Loop Control Sensors Solar Control (cover off) OPERATION- The solar loop control turns on the solar loop pump whenever solar energy is available and turns the pump off when sufficient solar energy is no longer available. (See the appendix for a detailed dis- cussion of control operation) CONTROLLER LOGIC- The solar loop control is a “differential temperature control”. It senses temperature at two locations and operates according to the difference between the temperatures at these two locations. When the temperature of the “collector” sensor is 8° F warmer, or more, than the “storage/tank” sensor, the output switch is closed. (that action turns the pump on) When the temperature of the “collector” sensor is only 4° F, or less, warmer than the “storage/tank” sensor, the output switch is opened.(That action turns the pump off ) SENSOR PLACEMENT - Place the “collector” sensor on the outlet pipe of the solar collector array and insulate well. Place the “storage” sensor on the pipe at the point where the flow from the heat exchangers come together in one pipe for return to the solar collectors. Insulate well. See page 16 of the installation manual for sensor placement details. Typical Control Setting Turn on = 8° Hi limit = 200° Optional Temperature Display SOLAR HEATING CONTROLS by Radiantec Company HEAT DUMP CONTROL Heat Dump Valve Place the heat dump valve in any hot water line and plumb to a suitable drain. Laundry room placement can be convenient. Setpoint Control Setpoint Control (cover off) OPERATION - The heat dump control lowers system temperature by automatically consuming some domestic hot water whenever excessive temperatures are detected.
