The earth is now going through a period of rapid climate change and the global temperature is increasing. According to experts, due to climate change, the whole world will face floods and droughts. Somewhere there will be heavy rains. Due to the melting of glaciers, rivers will flood and regions will suffer from drought. Rains and floods in Pakistan, while some regions of Africa and Latin America are suffering from drought. Rapid changes in temperature indicate that life will become unbearable in many regions of the world eight years from now.
Undoubtedly, Karachi is the largest city of Pakistan, but as a big city, its condition is quite alarming. One third of the total population of Sindh lives in Karachi. Extreme heat wave is continuing in the city of Karachi of Sindh province, the temperature in the city of Quaid is likely to go up to 38 degrees, while the intensity of heat will be felt up to 42 degrees. The Department of Meteorology has said that the sun is at its full strength in the city of Lights, the intensity of heat has increased due to the humid weather. They said that the current temperature of Karachi is 29 degrees Celsius, the humidity ratio in the air is 77%. Is. According to the Meteorological Department, winds are blowing from the western direction at a speed of 7 kilometers per hour across the city, the weather will remain hot and humid during the next 24 hours.
Today’s weather is telling that there is no scientist or alarmist, but instead we are complacent and fearless and are suffering the consequences of mismanagement. There is a gradual increase and scientists have warned that urgent steps are needed to save the earth from the destruction caused by climate change. Is it? Anthropogenic warming has increased carbon dioxide emissions, which increase temperatures. What is climate change? The climate of an area is the average over many years. Climate change is the change in this average. Earth is now going through a period of rapid climate change and the global temperature is rising. What does climate change mean? Climate change will change the way we live. This will create water scarcity and make it difficult to produce food. Some regions may become dangerously hot and others may become uninhabitable due to sea level rise. Extreme weather events such as heat waves, rains and storms will become more frequent and intensify, threatening people’s lives and livelihoods. Citizens of poorer countries are less likely to adapt and will suffer the most.
Forest fires are increasing air pollution, which is also affecting wildlife, reducing the number of wild to wild animals and leading to the extinction of many species of wild animals. Apart from this, it is causing lack of oxygen and excess of carbon dioxide. Deforestation causes floods because trees are like nails to the ground. Pakistan is one of the least forested countries in the region, with only 4% of its area covered by forests. The ozone layer is the most affected by air pollution. Which is the biggest threat to human life on earth.
Global temperatures are on an upward trajectory, fueled by greenhouse gas emissions as reported by the Environmental Protection Agency (EPA). The National Oceanic and Atmospheric Administration (NOAA) predicts a sobering future, with global temperatures projected to rise by a staggering 2.6 to 4.8 degrees Celsius by the end of the century.
In this context, energy-efficient heat pumps emerge as a beacon of hope. These innovative systems offer a sustainable solution for heating and cooling homes, potentially mitigating the impact of climate change. However, a new report by the Eneref Institute throws a bucket of cold water on this potential lifesaver. The report exposes a hidden danger lurking within the burgeoning market for budget-friendly heat pumps – their propensity for failure, posing a significant health risk to a vulnerable population in a warming world.
The report meticulously dissects the issue, painting a chilling picture of how cost-cutting measures in these budget heat pumps translate into potential failure points. Imagine a scenario where a searing heat wave engulfs a neighborhood. Inside a home equipped with a budget heat pump, the air grows thick and heavy. The evaporator coil, typically crafted from inferior materials in these models according to Eneref Institute’s analysis, succumbs to the extreme heat, freezing over and rendering the unit incapable of extracting heat from the stifling air. Panic sets in as the once-promised cool refuge transforms into a furnace. This scenario, far from being a dystopian nightmare, is a very real possibility with budget heat pumps.
When a heat wave hits, a malfunctioning budget heat pump becomes more than an inconvenience; it can be a matter of life and death, especially for vulnerable populations. The U.S. Center for Disease Control (CDC) identifies heat waves as a leading cause of weather-related deaths in the United States. With a warming climate, these events are expected to become more frequent and intense. The elderly and those with obesity (which the CDC reports has risen from 30.5% to 41.9% in the US between 2000 and 2020) are particularly susceptible to heatstroke, a condition that can be fatal without proper cooling. A malfunctioning budget heat pump during a heatwave can leave these vulnerable populations exposed to life-threatening conditions.
Eneref Institute’s report delves deeper, unveiling a multitude of vulnerabilities embedded within these cheap units:
- Frigid Flaws: Budget heat pumps often utilize subpar evaporator coils that struggle to perform effectively in scorching temperatures. These coils can freeze over, compromising the unit’s ability to cool the home precisely when it’s needed most.
- Leaky Links: Cost-cutting measures sometimes lead to the use of weakly brazed connections for copper tubing within the heat pump. These connections can develop leaks, allowing refrigerant to escape and rendering the entire system ineffective.
- Durability Deficits: In a race to the bottom on price, manufacturers of budget heat pumps may opt for flimsy plastic shells. These shells are prone to cracking under stress and sun damage, unlike the sturdier steel shells found in higher-quality models. This lack of durability translates to a shorter lifespan for the unit and leaves homes vulnerable during extreme weather events.
- Insulation Inertia: Cutting corners often extends to the insulation materials used in budget heat pumps. These units may utilize less effective insulation materials, leading to decreased efficiency and increased energy consumption. This not only negates the environmental benefits of heat pumps but also translates to higher electricity bills for homeowners.
- Fan Frenzy: In a bid to reduce costs, manufacturers of budget heat pumps may install smaller, less powerful blower fans. These fans struggle to circulate air effectively, compromising airflow and efficiency. Additionally, the high-speed operation of these smaller fans shortens their lifespan, leading to potential breakdowns during critical periods.
- Circuitry Conundrums: The report raises concerns about the quality of circuit boards used in budget heat pumps. These boards may lack crucial features like hardening techniques, making them more susceptible to damage and increasing the risk of complete system failure. Such failures often necessitate expensive repairs, further burdening homeowners during a time of crisis.
These vulnerabilities paint a chilling picture. When a heat wave hits, a malfunctioning budget heat pump becomes more than an inconvenience; it can be a matter of life and death, especially for vulnerable populations.
The report by Eneref Institute further raises a critical question: are these cheap heat pumps deliberately designed for short lifespans (planned obsolescence) to keep the replacement cycle churning? This strategy not only burdens consumers financially by forcing them to replace units more frequently but also undermines the environmental benefits of heat pumps by generating additional electronic waste.
