Abstract:

Efficient energy and its conservation is a great challenge for engineers. All the refrigeration and air conditioning machines consume large amount of electrical energy. To minimize its consumption various technologies are working day and night. As far as government of India is concern, it already started special norms which are standardized by BEE (Bureau of Energy Efficiency). Energy Standards are becoming more stringent and to meet up with them it is necessary to make refrigerators more energy efficient. Energy saving can be done either by optimizing subsystem related to cooling or Defrostin

Abstract:

The paper presents a literature review regarding defrosting methods for household refrigeration and heat pumps. The literature review covers the period between 2008 and 2020. A number of 61 papers have been studied. The literature review was conducted by dividing the defrost methods into passive and active. Passive methods involve surface coating and off-cycle. The active defrost methods involve reverse cycle, ultrasonic vibration, hot–gas defrost, electric heating and hot fluid. Surface coating and ultrasonic vibration are recent defrost methods proposed in the literature. Also, recently, pha

Abstract:

Wind evaporators are alternative evaporators for air source heat pumps which rely on wind-driven or natural convection to move air across the heat transfer surfaces. It is believed that, in certain climates, wind evaporators can operate satisfactorily with frost on their surfaces for extended periods of time and defrost passively during switch-off periods. If so, an active defrost cycle would be unnecessary in these climates. Wind evaporators present an opportunity for heat pumps to be less expensive, more reliable, and more energy-efficient. However, the heat transfer performance of wind evap

It is shown that for heating rooms and objects large in length and volume, the use of extended emitting pipes is most appropriate. A method for heating extended objects is described, in which the principle of radiation from radiating pipes with a length of more than 30 m is used in a garage-defroster of railway cars. The heating system of the garage-defroster includes a firebox-heat generator, long pipes of 90 m along the wagons, the control and instrumentation system A. The firebox and the control and instrumentation cabinets are installed in a separate room. The defrost system circuit is ess

Abstract:

This article presents the development of a resistive frost-detection sensor fabricated using Fused Filament Fabrication (FFF) with a conductive filament. This sensor was designed to enhance demand-defrost control in industrial refrigeration systems. Frost accumulation on evaporator surfaces blocks airflow and creates a thermal insulating barrier that reduces heat exchange efficiency, increasing energy consumption and operational costs. Traditional timed defrosting control methods can mitigate these effects but often lead to inefficiencies due to their inability to align with actual frost accum

Abstract:

It is widely known that the defrosting operation of evaporators of commercial refrigeration equipment is one of the main causes of inefficiency on these systems. Several defrosting methods are used nowadays, but the most commonly used are still time-controlled defrosting systems, usually by either electric resistive heating or reverse cycle. This happens because most demand defrost methods are still considered complex, expensive, or unreliable. Demand defrost can work by either predicting frost formation by processing measured conditions (fin surface temperature, air humidity, and air velocity

Abstract:

Proper control and performance of evaporators in food refrigeration facilities are vital to provide a suitable temperature regime, safety, quality and wholesomeness of refrigerated products at minimum electricity costs. When humid air passes along the surfaces of a low-temperature evaporator, frost is usually formed, which decreases the heat transfer efficiency. Frosting and defrosting phenomena have been extensively investigated for different industrial scenarios and extensive literature exists in the matter. However, no studies have been published so far to address in a comprehensive way the

We present results from sensory panels on fried burbot meat that had been frozen and stored for 5 months with three methods: (1) dipping meat in liquid nitrogen, followed by storage at –80°C; (2) direct storage at –80°C; and (3) direct storage at –18°C.

Abstract:

Researchers in the past have reported various methods to either retard frost formation or minimize energy expenditure during defrosting, but the methods reported in this paper is novel. Use of air flow during heating and defrosting cycles has not been studied and reported so far. The effect of using air flow during heating and defrosting cycles of heat pump were investigated experimentally. In the heating cycle, it is found that at higher air flow velocities, it is possible to retard the rate at which frost grows on the evaporator coils of the heat pump. Changing the air velocity from 0.8 m/s

Abstract This paper investigates the effects of frost formation on performance for an air-to-air heat pump. A transient model is used for evaluating frost formation on a parallel-plate heat pump evaporator. The frost formation model is derived by applying the equations of conservation of mass, momentum and energy, as well as some empirical correlations, to calculate the growth and densification of the frost layer. The model has been validated in a previous work by comparison with experimental results. In this paper, the frost formation model is incorporated into the evaporator subroutine of an
