2 NOMENCLATURE Parameter Value Unit Parameter Value Unit η η of water Dimensionless Dimensionless Dimensionless 1 INTRODUCTION The thermal performances of solar collectors are mentioned by Kalogeria [1, 2]. The structure and operation of several types of the most common solar collectors are reported in this paper. These collectors including: Flat Plate Collectors (FPCs), Evacuated Tube Collectors (ETCs), Parabolic Trough Collectors (PTCs), dish and Heliostat fields collectors (HFC) and Fresnel lens. The heating systems such as: FPCs and ETCs are generally designed with forced circulation of fluids between their tubes. In these thermal systems due to the pumps, there is no severe limitation for fluid flow circulation [3, 4, 5 and 6]. The water-in-glass Evacuated Tube Collectors are widely used in the world. The instantaneous efficiency and outlet water temperature of the collector in these systems are generally more than the flat plate collectors, because the heat losses of ETCs are lower than flat plate collector types [7, 8]. In these papers the efficiency of these collectors are expressed as linear regression of instantaneous efficiency against heat loss in selected hours in during chosen days. The vacuum tube solar collector water heating systems with natural circulation of fluid between the tubes and the horizontal tank above it are expressed by [9, 10, 11, 12, 13 and 14]. The characteristics of the optical efficiency are presented by experimental work [15]. The exergy and energy analysis of solar assisted heat pumps also is carried out by [15, 16]. In a few cases performance and efficiency of the vacuum tubes Solar Domestic Hot Water Systems (SDHWS) are done by overall heat losses of these systems. An overall heat loss coefficient of these collectors includes the irradiative and convective heat losses coefficients [17]. The performance of these types of the SDHWS are ideal, when the overall heat loss coefficients are minimized. The operation of the ETCs also is performed by U-tubes shape that its function is different from normal and common types of the vacuum tubes [18]. The performance of the vacuum tubes SDHWS are explained in a few works based on configuration of the integrated storage tanks [9, 19]. Some nodes are embedded in order to measure the temperature at different heights from the vertical tank. Vertical tanks are at ETCs with forced circulation of fluids or are accompanied with horizontal tank which increases the water outlet temperature of the horizontal tank [9]. The Tilt and Azimuth angles are investigated Journal of Science and Engineering / ISSN:

3 in some papers [20, 21 and 22]. These papers have shown that the inclination of collector effects on performance of the ETCs. The effects of Tilt and Azimuth angles in heat pipe (two-phase) evacuated tube SDHWS is commonly more than the single-phase ETCs SDHWS [20, 21]. Two common forms of the ETCs are including: Tilted- arranged and Horizontally-arranged, which are for the commercial-industry and domestic scales respectively. In Fig. 1. (a) Schematic of ETCs water heating system is shown. The nodes are mounted at different height of the vertical tank to measure the water temperature. Also the view of top section of the tube opening is depicted in Fig. 1. (b). Fig. 1. (a) Schematic of vacuum tube solar water heating system with Tilted-Arranged (b) Section of the tube opening 2 DESCRIBING THE CIRCULATION SYSTEM AND MATHEMATICAL METHOD A view of the fluid flow inside the pipes is displayed in Fig. 2. (a). The urban water circulates naturally in the tube throughout the day. This type of the solar thermal system starts producing the hot water using the sun heat during the day. Due to the different density between the cold and hot water, when the solar radiation encounters the black surface in inner tube of each vacuum tube the hot water of the tubes reaches the storage tank and replaced with cold water from horizontal tank to vacuum tubes. Outlet hot water at the highest height of the tank is used to load. The position of the solar irradiation in connection with each vacuum tube is shown in Fig. 2. (b). Aperture of the area in midday is greater than the other times. In the midday about %33 of absorber tubes of the vacuum tubes is exposed to the sun. Aperture of the area for each vacuum tube is obtained: That and are diameter of inner tube, length of each tube and number of the tubes respectively. Rate of the heat gain that reaches to each vacuum tube is given by: Journal of Science and Engineering / ISSN:

Also outlet water temperature of the collector is: η ( ) and are and respectively. are dimensionless number of Grassof, Nusselt, Prandtl. With considering as tilted angle of the collector, the dimensionless number of for the two concentric tubes that space between them is vacuum, is given by Eq. 6. having and, mass flow rate is given by: Also Solar Fraction (SF) of the evacuated tubes SDHWS is extracted from Eq. 8. It should be noted that the from Eq. 9. will be found Journal of Science and Engineering / ISSN:

5 3 TRNSYS SIMULATION The TRNSYS software is the most common program for simulating the thermal solar systems including: FPCs, ETCs, PTCs, Heat Pipe collectors and etc. The solar water heating system with single-phase vacuum tube solar collector is designed with TRNSYS16 software. The most important components in this simulation are: vacuum tube collector (Type71), horizontal tank (Type60k), weather data and daily load. Fig. 2.

Tabriz city has cold and dry weather Type71 and Type60k in TRNSYS16 For the simulation single-phase and two-phase vacuum tubes SDHWS we must use Type71 and Type538 as collectors respectively. As water is the fluid between the tubes and tank with different of colds and hot streams, then Type71 is used for this simulation. Type60k is stratified with some nodes in different temperature levels to measured water temperature at different heights of the horizontal tank. Characteristics of the vacuum tube collector and horizontal tank is presented in Table System simulation diagram in TRNSYS16 Simulation of single-phase vacuum tube SDHWS with natural circulation is performed under the different climatic conditions.

9 4.2. Performances of the nodes in Type60k Some nodes are stratified at different heights in horizontal tank. These nodes will cause water with different temperatures trend to values mentioned in Fig. 6. Performances of the water temperatures in the Type60k tank considering their sensors are shown in Fig. 6. T top is value of the hot water in highest height of the tank. The maximum and minimum values of the T top and T bottom in their best positions in Type60k are 72 C and 35 C respectively. The values of the T 2, T 3, T 4 and T 5 are different in the beginning. These nodes at different heights of the Type60k converge together and create the final value. The final value of the T top enters to water port in order to load and use for consumers. Fig. 6. Performances of the water temperatures nodes in Type60k 4.3. Daily curves of the outlet water temperatures and useful energy gains The performances of the ambient and outlet water temperatures in two-different climatic conditions are demonstrated in Fig. 7. These Figs including: curves of the outlet water temperatures of single-phase evacuated tubes SDHWS with natural circulation of the water between the tubes in Aug. 15 th and Feb. 14 th. The peak values of the outlet water temperatures in midday Aug. 15 th are 80 C (Fig. 7 (a)), whereas maximum of these values in midday Feb. 14 th are 70 C and 60 C in Zahedan and Tabriz city respectively (Fig. 7 (b)). The distance between two curves of the outlet water temperature of the collector in Aug. 15 th is lower than them distance in Feb. 14 th due to the low solar radiation intensity in Tabriz city in Feb. 14 th. Also performances of the useful energy gains and useful energy gains per aperture areas are drawn in two cities noted above. The values of the heat gains and useful energy gains per aperture areas in selected days in Aug. 15 th are slightly more than those values in Feb.14 th (Fig. 7 (c)). The values of these parameters in night are negative, because the hot water in horizontal tank consume by consumers. The difference between curves of the collectible heat gain in two cities in Feb.14 th is more than the difference in Aug. 15 th due to little solar radiation in days of the winter in Tabriz city (Fig. 7 (d)).

13 performances of the single-phase vacuum tube SDHWS that simulated using TRNSYS16 software can be seen in Table.2. These parameters are extracted in climatic conditions of Tehran city. Since the instantaneous efficiency of the single-phase water-in-glass vacuum tubes SDHWS is between 50%-60% [3, 9 and 10], the values of the heat losses in vacuum tubes solar collectors must be lower than If the values of instantaneous heat losses in these systems are higher than 0.025, values of the instantaneous efficiencies of these systems in the linear regression curves of the efficiency against heat loss will be lower than 0.5, that is not acceptable [9].

Optimization of vacuum tube solar collector performance in Tehran city In order to improve the efficiency of the single-phase solar water heating system in Tehran city, performance of this system is optimized using Genetic Algorithm (GA) Toolbox in MATLAB software. Since objective function in GA must be minimum, reverse efficiency is considered as objective function in this paper. So the optimum value of the efficiency will became maximum.

15 In equations, instead of phrases d, l, u and t we used x 1, x 2, x 3 and x 4 respectively. Considering the thermal conductivity of the genus tube is 50 W/m K, the Eq. 1. can be written bellowing: Also mass flow rate of the water from Eq. 7. can be modified as Eq. 11.

Since the water flow between tubes and horizontal tank is laminar flow, the dimensionless parameter in this system is second constraint and those values must be lower than Two constraints of this optimization can be written following Eq. 14. and Eq. 15.

Also the generation number which in the objective function is optimized should be mentioned. Whilst the average distance between individuals that produced in each generation become close to the previous generation, objective function desires to reach the optimum value. In fourth generation, the average distance between individuals is gets close to zero number, so the objective function is minimized and it s value becomes Fig. 10(a). So the efficiency value of the optimum is The convergence curve of the Journal of Science and Engineering / ISSN:

The most important simulated components in this paper are: Typey71 for ETC and Type 60k for horizontal tank with five nodes within. The daily curves for the G coll, G tilt and useful energy gains in hot and cold days of the year in three cities are shown. Also the yearly performances trends of the useful energy gains, efficiencies and solar fractions are validated and these values are similar together. The inlet, mean, ambient and outlet water temperatures of the collector, instantaneous efficiencies and daily heat losses in six selected days in spring and summer seasons are measured. The values of the daily and monthly heat losses in single-phase vacuum tube SDHWS must be lower than 0.025, which makes the daily and monthly efficiencies in these systems become at least 0.5. Optimization of the thermal efficiency of this collector with objective function as reverse efficiency is carried out with Genetic Algorithm Toolbox in MATLAB. Design variables in this optimization including: inner tube, length of tube, velocity of natural circulation of the water between the tubes and tilt-angle of the collector that are optimized. Optimal efficiency is , and this value is compared to average yearly efficiency. Improvement percent of the efficiency in climatic condition of Tehran city became 12.4%. REFERENCES [1] Kalogirou A.
